Like I said in your last video: Get a roll of plastic liner and use a hot wire to make long tubes/bags (like vacuum bagging). Push them over your anfo blow pipe and blow the anfo into the plastic tubes to keep it dry. You will never have a problem with wet anfo. You also need to get a mini skid loader. They are o cheap and would save you 2 days of mucking per round. It will pay for itself in a week.
You have to stay on top of clearing debris from the bit. Once the debris becomes compacted it is extremely difficult to clear. The longer the drill stem, the worse it gets. Don't spare the water.
Almost like a giant condom. It sounds good on paper. But I am no miner. Never even been underground. But the logic of it is sound. Getting a mini skid up there and in the mine would have it's own unique struggles. But it would help. If nothing else... It would save their backs.
@@vinnieg.6746 You should try underground, even if it's just in a tourist-trap cave somewhere. It's a very different experience from anything you're used to.
@@danmerillat Not really a fan of tons of rock over my head. It's an unrational fear l know. A friend of mine went cave spelunking (l think it's called). One of his group got stuck heading down headfirst. Authorities tried to get him out. They were never able to rescue him. It's closed off now. But l won't jump out of a perfectly good airplane either.
Next time you encounter a 'slip', don't drill further. This is now you 'new' drill depth and the rest of your drilling should go no further. Stem the 'slip' end, pack with explosives and stem the outer end. This method should reduce the time spent dealing with stuck drills. Really enjoying your programming.
If you have a jumbo, no problem unsticking, usually. If you need a 10 ft. round, and say the mud seam is 5', load the primer cartridge/booster at the back, but also leave a tracer of 25-50 grain cord attached to primer. Stem 6" or so both sides of the seam. The det cord will detonate the powder without causing the mud seam to cut off the other holes. Only works with stick powder with 25 grain sensitivity .
Well darn, that went well until it didn't. This seventy year old fart, got sore and tired, just watching you muck out that first blast. Fascinating process. Were I a younger lad I might ship out west to help and learn. Now, I'll sit in my big comfy chair, and cheer you boys on. Thanks for showing us how its done, including the fails.
So when we were shooting shots in similar conditions we would guage our stemming pack against the path of least resistance. In your particular circumstances there, I wouldn't have stemmed the burn and used less stemming pressure accordingly in your diamond, square and perimeter loads. It's going to travel the path of least resistance so just load your stemming with that in mind. All I've ever worked with was fractured granite and you just develop a feel for it eventually. You typically don't need as hot of a shot and you're definitely going to have radical fly rock when you're shooting a slip/fault or fractured rock. We typically wouldn't try to shoot past a difficult fault. We would get it dealt with, then move forward. Otherwise, you're just going to fight it and it's typically slow and frustrating. Loving what you guys are doing and the content you're putting out. I spent three weeks vacationing there last fall. Would have enjoyed running into you and looking over your operation. I plan on coming back next September. Maybe we can arrange to meet. Good luck guys!
I was wondering if filling the holes to the slip with waste so that you just take the section in front of the slip would have helped. As you point out, you'll just fight it if you don't.
I can't remember if your site has a step up.trying to think if you could get small power barrow. Or can you anchor a truck winch at the drop down that can pull more than one trolley and stop at waste piles and side dump Just see the volumes you are trying to move putting ideas out there. Fully aware you have a shite tonne more experience
Thanks for showing the mishaps, it is the best teacher. Keeps your channel real!. A couple of comments from my armchair. Stop at the slip, like others have said. Loading all stick powder will help, un less the slip cuts off the column, and your powder doesn't blast across the gap. On lifters, you don't always have to tamp the sticks, especially on a tight spacing. Add 3/8" stemming. By not tamping the sticks and the 3/8", you have a French drain to allow water to drain, and not back up the slip. Load ANFO into a plastic sleeve. For an 1 3/8" hole, a lay flat sleeve of 2 1/2" is best, I use the 6 mil poly. Don't hammer on drill steels! It will break them on the next round. I use a handy man jack with a couple pieces of 3/8" steel bolted to the side of the lifting tongue. I always wish I had a special drill chuck with a water/air valve I could slip over the shank, to assist with unsticking the steel.Turning with blow air helps a lot. Of course when the bit is plugged that much, you are surely screwed. Extra water and slow to hand rotation of the steel with a wrench, will sometimes keep the bit from plugging. You are at the mercy of the drill gods though. A bore hole camera would be a good addition to your arsenal of video toys. They aren't too much $. I can't wait to see you start hitting some large vugs for another interesting video. Let the cursing begin.
In 1965, my dad was widening Hyw 88 and training an apprentice. The apprentice loaded 3 holes wrong. Dad had to drill next to those holes. He hit unexploded dynamite that threw him 15 feet backward, the jackhammer forward 10 feet, and the 6-foot drill steel corkscrewed landed 10 feet to the left. His face was potmarked with rock shards, it blew his goggles off and respirator off. His torso was peppered with rock shards. Dislocated his collar bones and shoulders. An 80-pound rock landed a foot from his head.
OMG! That blast was over in a split second! It is amazing - yet terrifying - what happens with the use of controlled explosives. In 1965, that was all still 'hands on' I'm guessing. The knowledge, experiences and safety around this field has come a long way for the better. I'm sure his trainee never will forget unless he left that job alone. As a nurse, I've got to ask if this killed him or made him disabled?
hey Jason, it’s Denis again, I’ve watched every single episode and at first I commented on every show but I stopped because I didn’t want you to think I was feign critical of you guys. For greenhorns, you guys are doing a good job. May I suggest a few tips to make your lives easier. I’ve been a hardrock miner for 27 years contract mining fir the best contractors in the world. When you encounter water, it’s best to use stick powder but if you have to use andi you can get plastic sleeves to keep the anfo dry. You should stick prime in faces that are giving water and if you encounter a slip prime at the toe of the hole and after the slip with the same cap number. that way the whole hole goes. When you are using stick powder slice the powder down the middle length wise about 2/3 the length in the middle of the stick and tamp, and tamp it hard. Don’t worry about setting it off, you won’t. Stick powder nowadays isn’t usually nitroglycerin based so it won’t blow when ya tamp it. i’ve blasted thousands and thousands of rounds and never ever stemmed the holes and never had a oroblem with blowouts. If the holes are blowing out you aren’t ramping it hard enough or the powder is cold and hard. split it and that will make it tamp and compact the powder and it will stay in the hole whe blasted. Trust me my brother, you guys work way too hard to have to do it twice. I’m not writing this to brag, i’m writing this to save you time energy and for safety. Misholes are one of the most dangerous things in mining and i’d sure hate for one of you to drill into a mishole. Judging by your ground I’d drill your lines 18” apart and put a row of bullshit holes between your breast and back holes. that will lessen the amount of force pushing on the ground on the back and will make for nice solid ground on the back. Hats off to you gents and I truly wish you gents the best. Once you guys get good the two of you can drill an 8’ round 8’x8’ load, blast and muck out if you had a slasher or scoop so as you guys get better you have a chance to increase your production greatly and i’m sure you will. BTW help each other collar take 15 mins and drill each hole 2 inches then go to the next, that way you guys aren’t fighting to collar the holes in the right place you can just go from hole to hoke without having to fight to collar the hole. This will all come in time my friend. when you get into muddy ground move your leg more up and down so you aren’t putting do much pressure on the drill and cause your steel to mud. These are just things you willl learn with time. drink plenty of water, when you are dry, it takes away all your power, stay hydrated. happy drilling. I wish Zi could be there for a couple rounds to show ya guys. I sure miss mining. as sick as it sounds, I didn’t think i’d ever miss drilling on a jackleg but I do. kk be safe and God bless ya!!!
As much as it sucks, in muddy slips where gasses are going to shoot the slip and cause anfo gaps, it might save time in the long run to just stop drilling at the slip, do a shorter blast to expose the slip, then work from a clean face.
That's what I was thinking. Another commenter mentioned washing out as much clay as possible and filling with concrete. I would think you'd have to re-drill but a guaranteed blast is better than gambling and losing.
Jason and Harry, I want to thank you both for always showing everything. I think that a person who is willing to share, explain, accept, plan and ask for advice, is someone to be respected. That is why I watch only a few people on here closely. I want to see the reality; both highs, lows, problems, solutions and everything else. Trying to sugar coat an error, or cutting out real life events, makes me distrust you. Thank you for sharing with us! Blessings from Alabama ❤️
Your still my favorite miners, blasters and mucker truckers... thanks for staying humble enough to video and talk about thing's when they don't go so well. Take care and stay safe, may every pan smile back at you with a golden smile. Till the Next. ... going to watch the S&J drop now... bye, see meeee. ⛏⚒⛏
On blasting across slips, I know the cast blasters in Wyo would try to put more than one cap/booster in each hole, timed to the same timing, but located on either side of the soft slip plane, to make sure each side would start/keep going.
I spent a couple ore seasons back in the 1970’s working in an open pit iron mine. I was a blasters helper from time to time dropping 4-5 50 pound Monsanto charges down each hole and tamping them when they were loaded. We’d blow about 30 holes at a time and moved a quite a bit of material. It was a great time and a wonderful job that paid very well. But, as I said, that was open pit. If I would have had to put in time in the same conditions you guys are working in, I’m pretty sure I would have begged to do some other job.
I use a mould-able damp clay to pack off/ stem the drill holes after the holes loaded with ampho , works a treat in my mine , but I don't have water problems or slip problem. The clay really supercharges the blasts breaking power , this was a trick my father taught me that they used in the old coal& opal mines, might help you , but your local geology is way different to my gold mine here in Australia, keep punching men . Thanks for sharing 👍
Yes, clay is way better for stemming, offers the most resistance. Slicing the sausages open and tamping in wet holes helps greatly. Minimum 2 sticks, when the water stops, load the rest of the hole with ANFO.
You put plastic first into the hole, then you put sharp gravel 3-8mm that makes a plug in the bottom, after than you put stick. You should also try to drill downwards to make it easier when you have to plug the bottom. A self loading micro dumper would be great for removing the pile.
@@GodsBattleAx don’t drill downwards! If your ground is giving water your hole will fill up with water. drill on a very slight uphill angle and the water will drain out and it’s easier to pull out the steel after you blow your hole.
@@denisrowlett9829 You didn't understand. Only drill downwards when you have to plug the bottom of the hole.. Water is not a problem, just blow it out with pressured air before loading it. Have you done any blasting?
Love all the constructive comments for your viewers Jason! Outstanding community of viewers. Learning a lot and I will never put it into practice that I know of. Jason keep up the outstanding work and effort. Long time viewer and subscriber.
Thanks for showing this, Jason! It looks like you have alot of experienced hard rock miners who are following your channel! I see lots of what sound like good advice and years of experience in the comments. No other channel on RUclips has anything, even remotely like yours.. Well except Jeff's channel, too! You are a good man because many people wouldn't be willing to put their mistakes on video for all to see, much less appeal for advice.
Wow! Now I get it. To be a successful miner, it is most necessary to enlist the assistance of an absolutely top-notch Mine Operator. Any ol’ body can muck all day. What counts is how ya deal with the never-ending variety of challenges and problems that mining surely provides.
I like how your blast hole density has shattered to the rock to an ideal size for your mini milling system. The slips and rolling of the vein is classic saddle reef, I'd expect the vein to roll into a steep fold limb, become much thinner. The grade of the steep vein ore zones was traditionally the richest ore. I suspect you have an asymmetric fold system, the crest/hinge zone has the nearly flat thick vein emplaced in the zone of maximum dilation which is what you have been drifting through. You're now entering the zone of rolling over into the steep limb. One of the nice things about these types of ore bodies is that the vein system can repeat several times as a stacked set within the fold.
Work fascinates me, I can sit and watch it for hours. AND I'm glad it's me sitting here watching you blokes instead of the other way around. Can't wait til you reach the raise and make life easier for yourselves.
When you have a consistent slip back in there, once you recognize it, you want to focus on the burn. You can stem the back of the holes that went through the slip so the explosives are forward of the slip, and stem the front of the holes too. Don't drill any more holes than you need to for a good burn, and don't any more than you need through the slip. You can sometimes measure the depth to it. Load it with the most powerful explosives you have on hand. The goal is just to get a good burn. Basically what you did to fix the problem, but with foresight not to trust a bad slip to behave well. What starts badly usually ends badly. You forgot the "making big ones into little ones" program.
While what I am about to say is not seen by all miners as a realistic way of approaching this situation, the way that some professionals approach cracks in a face like that is to wash the holes out until mud stops running and then fill them with rapid setting cement. The cement need not be super strong, because it is only there to act as sideways stemming. Its job is to reduce the amount of cross flash between holes. Other than that, one should actually get a whole lot of high shock stick and put in there. When dealing with slips, especially where there is a very wide area of exposure, low brisance charges are less prone to clean detonations. I realize that higher brisances also equals increased hazard, but it is one of the more popular ways to break past such gaps. While I am sure there are other ways [I can actually think of a few], those are the most common, and most effective ones.
Upfront: I know nothing about blasting or mining, but how about placing stemming in the drilled holes when you know you have a slip in the back first, then place the explosives and finish off with stemming. That way, I think the gasses of the explosives won't shoot up the slip, but should stay contained between the stemming in the back and the front. I'm sorry if I'm being stupid or ignorant because I know nothing about mining whatsoever, just thought I'd share my simpleton idea. And I'd like to use this moment to show my appreciation for you guys bringing this content online for me to enjoy! I could only wish to live in a place where I would be able to do something similar. THANKS!
What about putting bentonite in the hole to cement a solid hole before blasting. You might be able to turn the water off.. I also thought maybe drilling a hole just to let the water flow.
that was my thought as well - a slip like that is just another open end, except with the added "bonus" of being able to disrupt your other holes. Drybagging the anfo would mean you don't need to use stick powder for wet holes anymore.
Back when I was a coal miner, we had a similar problem, so the old man came up with a solution. We put dummies in and tamped them tight, then we set the powder and put the dummies in and tamped them too. Dummies were made out red clay. Worked pretty breaking the rock in those rolls. 4:08
There’s not ver many honorable people on RUclips. You sir are one of them. Showing mistakes is more important than successes. Making mistakes is how humans learn. 98% of content creators would have left this out and pretended they were awesome.
Hi Jason, Looking forward to the next video to see what the slip looks like. When I ran into water at our Nevada mine, we used florists putty - easy to use and it worked 90% of the time. Someone else commented about using plastic bags for the anfo - an excellent idea. Hopefully no more slips! Thumbs up! You and Harry stay safe!! Jim
Someone needs to do a montage going back over several videos of Jason's face just after he hears the boom when igniting the explosives'. Every time Jason "booms" the mine he can not hold back his grin. A montage of the different grins would be priceless!
Some good comments below, some not so much, the best one is cut off drilling at the mud and load with stick powder when wet. I know you were limited by supply but that was in your control. Keep it safe and simple. cheers
This is real world stuff, best TV in a hundred years. The good bad and the ugly.!!! Love this! We know Jason is so honest.!!! Reality!!!!!!! Thank you for this.
Jason, buy a button bit grinder! A hand held from Rockmore, Wilsonville, Ore. $1,000 plus a couple right size and shape pins.Grind the gauge angle back on a bench grinder. Don't hit the carbide though. You won't get stuck as much. Get ballistic pins and your drill will fly through that rock. Less rebound to the drill and your hands with a sharp bit.
Thanks for explaining all the details. It is entertaining and informative. Adding the video recording on top of the actual mining I'm sure is a pain in the backside.
Always show the problems too. A lot of us will be interested in them and in how you deal with them, and you'll get a lot of advice (some of it even from people who know what they are talking about haha) I agree with what other people said about not trying to blast through slips, and in the future if you're in this situation put perhaps stem rock in the back of the hole so the blast doesn't get to the slip much.
Great video even if it all didn't go according to plan...watched every minute very interesting. Sorry I have no mining experience so I can't offer any words of wisdom but I'm rooting for you two. You both have a great work ethic and make a great team hope it all works out for you and you strike it big time! Thanks again.
Jason thank you for always showing the entire process both good and bad. Its paints a true picture of the labors of mining and what it takes to get the job done.
Excellent vid, really appreciate the honesty. I am a prospector with a couple of placer claims. It is great to see the other side of the fun. You two are real diehards. hope that shot went well. Looking forward to part 7.
Can you roll up some stemming deep to block the slip side? Double stemming perhaps? Add some expanding dry grout they use for breaking rocks to your stemming mix. The expanding grout might plug off your water. Pack it with wads like black powder gun and let the grout do its magic. On second thought expanding grout might make heat and Ka-pow you :(
I agree on using the expanding grout or roof bolt epoxy, otherwise if in mud, then drill/shoot the pattern shallow just to clear out. I wouldn't worry about the heat from the grout though.
I appreciate you’re sharing this also, because those "production interruptions" sometimes happen, and we blasters must be able to fix and handle that in a safe and controllable way. -Do you not use a booster charge for the ANFO? Hope you get it sorted out, be careful. -My advice is to pack approx. 50g of blasting dough/NG-base + blasting cap at the end of each hole to detonate the anfo that is visibly left. Good luck 🤞🏻
My great grandfather repeated over and over, to his deathbed, if you're drowning, make a bigger hole. I think he was trying to say, when you have a bunch of water. Drill a bigger hole so you can load it heavier. Not sure if it will help, but he never steered me wrong. And after watching this vid, I think this is exactly what he was talking about. And it makes sence. Risking resources that never pan out. Bro, load a larger charge or 3.
I don't think you made a mistake. I know you drilled into an obstacle. Now you are dealing with that obstacle, bummer for sure. Great entertainment, though!!! Thank you both!!
glad to see my dumb traffic cone suggestion awhile back has worked out for you. for wet holes and anfo i'd do a thin slick plastic wrap ( like what i put over the windows in winter ) over the blow in tube that's sealed at the end. blow in your anfo and give it a twist to seal and then pack it in with the stemming. when the steel gets stuck in the mud of the slip, try blasting around the outside with your water hose. since the hole is bigger than the steel it might save you some beating on it to get it free. i've never been a miner, but sometimes guesses from an outside perspective help.
In slips use a good backer like sand, cardboard ect pack it all the way in the back closest to the slips right next to that use ammonia (fertilizer) packecked in at least 3/4” per foot, then the next should be pretty routine you ampho, tnt or nitro ect whatever your main charge is when finishing up pack every hole with more packer material like fertilizer wadding ect and pack it tight carefully so you don’t damage your caps, wires, or det cord then fire in the hole
usually with small hole blasting if you get to a slip with water and mud you drill less deep than the slip - if you get into the slip you first put stemming then explosives to not blow out into the slip make a weaker shot to remove rock up to the slip - then use compressed air lance and pressurized water or clay spades to get to the other side of the slip - if necessary add some wall shaving charges to the next blast to expand the tunnel infront of the slip if you got open pit mining conditions and have a drill bigger than 4 inches and drill vertically you just go a bit deeper and add more stemming - some load two blasting caps on either side of the slip without any delay or lay deth cord into the hole along the charge to bridge the slip if you drill into a face / vertical cheapest is to just do a short blast, muck out clay and shave the walls
To me it seems simple when you have a slip pack stemming first then your anfo and then stemming to seal. You guys are doing great keep up the exercise and you will be half the men you used to be! :)
Genuinly enjoy watching, You two make a great team. would love to meet you both. Need to buy another bag, bought two from last season has been fun going through them, not done though. Thanks.
That fail is exactly what I warned you about in a previous comment. Your fixation on stemming did not help you when you ignored all the other problems. Centre prime. Collar prime. Drill all your non burn holes first to find the best ground and move your burn around accordingly. Would have been best to pull your cut up but honestly, hindsight’s a curse sometimes and I think almost everyone needs to learn the hard way or the lesson won’t stick. Take it as a lesson learned. Could have been worse. ANFO + water + voids + mud + shears/joints … if it had worked it would have been a minor miracle. I’ve seen fired faces with the paint still on them. What you had wasn’t pretty but isn’t all that bad since it seemed to have allowed the water to drain for the next firing. Good luck. For all I spend most of my time viewing your content cringing I have the utmost respect for you and your persistence, and I feel I would very much enjoy working with you. You are a true champion. Best of luck. I would just say that where I am in Western Australia we use entirely different explosives, initiating and detonating systems so it’s an eye opener to see how you guys do it. ANFO is about the only common factor. So strange.
Pre-stem a lighter charge at the mud seam, then stem as usual. It should expose the seam to tell you more info about what's next. I've drilled and blasted rock with mud seams before and it seems to work the best.
"excitedbox" has a great idea! I was thinking about pre making rounds using thin walled 3/4" pvc pipe. Seal the end, send in the wire and primer, fill it with ANFO, seal this end and viola. Make them ahead of time, and stop messing with the ANFO blower altogether.
Really enjoy your videos! Hope your paying Harry good; I enjoy watching you guys work. Always ready for more smelting experiments too! Thanks for sharing.
I don’t know anything about mining but I’m pretty observant to things that are happening…I’ve been watching you for a while. I think it’s cool that you did post this. It get a lot of eyes and ears on the situation. So on this particular blast I noticed that there was not a pause between the two different sounds of blasts like in your previous blastings… fingers crossed for a better out come on this round
I wish I could work with you guys for a year but I'm in a spot in life where I cant unfortunately. I hope you find someone who enjoys it just as much as you do.
Been there and done that. Stuck drill steels and plugged air tubes. Dad often drilled 16 foot holes on his load claims. None of the new stuff you have in blasting. Just 40% TNT with electric caps. Deep holes, he layered the charges and mud. My job was cleaning the plugged air tubes and changing the bits.
if you have a problem with the slip, you can stem the slip up, and use a lot less stemming on the face. once the face is within a foot of the face, just drill right past it, and stem the slip on the other side of the blast.
You can make your own caps pretty easily. Also you cen increase the power of the anfo and sensitivity to a cap by adding a small amount of super fine aluminum dust to it, about a teaspoon full for every 5kg and roll it in a 5 gallon bucket till the grains are all silvery gray. Adding a thin plastic liner will stop the wet powder misfire issue. Also do be careful about wet slip fault areas as they might have lots of ground water behind them.😮
You guys are studs 500 plus buckets of mucking. Don't beat yourself up about the last blast. Things happen especially in slips with dumb clay blocking your drill holes. Look forward to see how this last blast went.
you are dealing with best guess behind the face. as they say shit can and will happen. Mr. Murphy always makes a visit no matter what.. Still doing a great job
The easiest and most efficient is stop at the slip stem in a little bit and blast to that depth Concrete in grouting, etc. etc. just takes more time and money lesson learned. That’s how you become a pro so I’d say you’re there now 16:09 you load 16 tons whadda ya get another day older and deeper in debt saint peter don’t you call me cause I can’t go I owe my soul to the company store…that’s a coal mining song but I think it fits lol back to the vid…. I have a sneaking suspicion you will lose your vein at the slip. Hopefully it will reappear at some point great video even though it was a bummer thanks for sharing. See you on the next one.👍🏼👊🏼
Thank you for sharing your failures with us, it's super important to improve the knowledge of everyone. The mucking is really a pain, so you should invest in an old pneumatic mucking machine, like you say the most expensive is the labor so it is a small investment with a big benefit. good luck for the next.
The mucking will continue until morale improves
Yes the monotone sad can be a cancer to a crew. Always be positive
@@Spawn303 Perfect Comment!!
@seldoon_nemar that would make a great slogan on a Mount Baker mining T-Shirt!
That and a I ❤️ Stemming slogan on a T-Shirt.
Bahahahahahahahha
For those who have seen the movie Holes, “ I’m tired of this Grampa !” “That’s too Damn Bad! You keep digging!” 🤣
Like I said in your last video: Get a roll of plastic liner and use a hot wire to make long tubes/bags (like vacuum bagging). Push them over your anfo blow pipe and blow the anfo into the plastic tubes to keep it dry. You will never have a problem with wet anfo.
You also need to get a mini skid loader. They are o cheap and would save you 2 days of mucking per round. It will pay for itself in a week.
You have to stay on top of clearing debris from the bit. Once the debris becomes compacted it is extremely difficult to clear. The longer the drill stem, the worse it gets. Don't spare the water.
Almost like a giant condom. It sounds good on paper. But I am no miner. Never even been underground. But the logic of it is sound. Getting a mini skid up there and in the mine would have it's own unique struggles. But it would help. If nothing else... It would save their backs.
@@vinnieg.6746 You should try underground, even if it's just in a tourist-trap cave somewhere. It's a very different experience from anything you're used to.

Next time you encounter a 'slip', don't drill further. This is now you 'new' drill depth and the rest of your drilling should go no further. Stem the 'slip' end, pack with explosives and stem the outer end. This method should reduce the time spent dealing with stuck drills. Really enjoying your programming.
I was about to write the same thing. Drilling and blasting just short of the slip should leave the flat face of the slip.
100% agree, I can feel their pain, I'm saying to myself, stop there guys.
Came to comment the same thing, stemming first, then gel/anfo and then stem the outer. Make a sandwich with it.
Nailed it. Worked with explosives for 45 years.
If you have a jumbo, no problem unsticking, usually. If you need a 10 ft. round, and say the mud seam is 5', load the primer cartridge/booster at the back, but also leave a tracer of 25-50 grain cord attached to primer. Stem 6" or so both sides of the seam. The det cord will detonate the powder without causing the mud seam to cut off the other holes. Only works with stick powder with 25 grain sensitivity .
Well darn, that went well until it didn't. This seventy year old fart, got sore and tired, just watching you muck out that first blast. Fascinating process. Were I a younger lad I might ship out west to help and learn. Now, I'll sit in my big comfy chair, and cheer you boys on. Thanks for showing us how its done, including the fails.
I am right there with you. My mind is willing but my body says sit back down in my recliner.
So when we were shooting shots in similar conditions we would guage our stemming pack against the path of least resistance. In your particular circumstances there, I wouldn't have stemmed the burn and used less stemming pressure accordingly in your diamond, square and perimeter loads. It's going to travel the path of least resistance so just load your stemming with that in mind. All I've ever worked with was fractured granite and you just develop a feel for it eventually. You typically don't need as hot of a shot and you're definitely going to have radical fly rock when you're shooting a slip/fault or fractured rock. We typically wouldn't try to shoot past a difficult fault. We would get it dealt with, then move forward. Otherwise, you're just going to fight it and it's typically slow and frustrating. Loving what you guys are doing and the content you're putting out. I spent three weeks vacationing there last fall. Would have enjoyed running into you and looking over your operation. I plan on coming back next September. Maybe we can arrange to meet. Good luck guys!
I was wondering if filling the holes to the slip with waste so that you just take the section in front of the slip would have helped. As you point out, you'll just fight it if you don't.
Am sure he will be happy to have an extra hand with experience
I can't remember if your site has a step up.trying to think if you could get small power barrow.
Or can you anchor a truck winch at the drop down that can pull more than one trolley and stop at waste piles and side dump
Just see the volumes you are trying to move putting ideas out there.
Fully aware you have a shite tonne more experience
I'm absolutely stunned at the number of people who are experienced in blowing stuff up. Seriously, the comments are a demolitionist class. Nice 👍
Thanks for showing the mishaps, it is the best teacher. Keeps your channel real!. A couple of comments from my armchair. Stop at the slip, like others have said. Loading all stick powder will help, un less the slip cuts off the column, and your powder doesn't blast across the gap. On lifters, you don't always have to tamp the sticks, especially on a tight spacing. Add 3/8" stemming. By not tamping the sticks and the 3/8", you have a French drain to allow water to drain, and not back up the slip. Load ANFO into a plastic sleeve. For an 1 3/8" hole, a lay flat sleeve of 2 1/2" is best, I use the 6 mil poly. Don't hammer on drill steels! It will break them on the next round. I use a handy man jack with a couple pieces of 3/8" steel bolted to the side of the lifting tongue. I always wish I had a special drill chuck with a water/air valve I could slip over the shank, to assist with unsticking the steel.Turning with blow air helps a lot. Of course when the bit is plugged that much, you are surely screwed. Extra water and slow to hand rotation of the steel with a wrench, will sometimes keep the bit from plugging. You are at the mercy of the drill gods though. A bore hole camera would be a good addition to your arsenal of video toys. They aren't too much $. I can't wait to see you start hitting some large vugs for another interesting video. Let the cursing begin.
In 1965, my dad was widening Hyw 88 and training an apprentice. The apprentice loaded 3 holes wrong. Dad had to drill next to those holes. He hit unexploded dynamite that threw him 15 feet backward, the jackhammer forward 10 feet, and the 6-foot drill steel corkscrewed landed 10 feet to the left. His face was potmarked with rock shards, it blew his goggles off and respirator off. His torso was peppered with rock shards. Dislocated his collar bones and shoulders. An 80-pound rock landed a foot from his head.
OMG! That blast was over in a split second! It is amazing - yet terrifying - what happens with the use of controlled explosives. In 1965, that was all still 'hands on' I'm guessing. The knowledge, experiences and safety around this field has come a long way for the better. I'm sure his trainee never will forget unless he left that job alone. As a nurse, I've got to ask if this killed him or made him disabled?
@@susanturcotte3176 It fucked him up, pardon my French.
hey Jason, it’s Denis again, I’ve watched every single episode and at first I commented on every show but I stopped because I didn’t want you to think I was feign critical of you guys. For greenhorns, you guys are doing a good job. May I suggest a few tips to make your lives easier. I’ve been a hardrock miner for 27 years contract mining fir the best contractors in the world. When you encounter water, it’s best to use stick powder but if you have to use andi you can get plastic sleeves to keep the anfo dry. You should stick prime in faces that are giving water and if you encounter a slip prime at the toe of the hole and after the slip with the same cap number. that way the whole hole goes. When you are using stick powder slice the powder down the middle length wise about 2/3 the length in the middle of the stick and tamp, and tamp it hard. Don’t worry about setting it off, you won’t. Stick powder nowadays isn’t usually nitroglycerin based so it won’t blow when ya tamp it. i’ve blasted thousands and thousands of rounds and never ever stemmed the holes and never had a oroblem with blowouts. If the holes are blowing out you aren’t ramping it hard enough or the powder is cold and hard. split it and that will make it tamp and compact the powder and it will stay in the hole whe blasted. Trust me my brother, you guys work way too hard to have to do it twice. I’m not writing this to brag, i’m writing this to save you time energy and for safety. Misholes are one of the most dangerous things in mining and i’d sure hate for one of you to drill into a mishole. Judging by your ground I’d drill your lines 18” apart and put a row of bullshit holes between your breast and back holes. that will lessen the amount of force pushing on the ground on the back and will make for nice solid ground on the back. Hats off to you gents and I truly wish you gents the best. Once you guys get good the two of you can drill an 8’ round 8’x8’ load, blast and muck out if you had a slasher or scoop so as you guys get better you have a chance to increase your production greatly and i’m sure you will. BTW help each other collar take 15 mins and drill each hole 2 inches then go to the next, that way you guys aren’t fighting to collar the holes in the right place you can just go from hole to hoke without having to fight to collar the hole. This will all come in time my friend. when you get into muddy ground move your leg more up and down so you aren’t putting do much pressure on the drill and cause your steel to mud. These are just things you willl learn with time. drink plenty of water, when you are dry, it takes away all your power, stay hydrated. happy drilling. I wish Zi could be there for a couple rounds to show ya guys. I sure miss mining. as sick as it sounds, I didn’t think i’d ever miss drilling on a jackleg but I do. kk be safe and God bless ya!!!
Thanks old timer
As much as it sucks, in muddy slips where gasses are going to shoot the slip and cause anfo gaps, it might save time in the long run to just stop drilling at the slip, do a shorter blast to expose the slip, then work from a clean face.
That's what I was thinking.
Another commenter mentioned washing out as much clay as possible and filling with concrete.
I would think you'd have to re-drill but a guaranteed blast is better than gambling and losing.
Jason and Harry, I want to thank you both for always showing everything. I think that a person who is willing to share, explain, accept, plan and ask for advice, is someone to be respected. That is why I watch only a few people on here closely. I want to see the reality; both highs, lows, problems, solutions and everything else. Trying to sugar coat an error, or cutting out real life events, makes me distrust you. Thank you for sharing with us! Blessings from Alabama ❤️
Integrity is huge and like sense, not so common anymore.
It was hilarious when Harry said he couldn't wait to get back to mucking.
Your still my favorite miners, blasters and mucker truckers... thanks for staying humble enough to video and talk about thing's when they don't go so well. Take care and stay safe, may every pan smile back at you with a golden smile. Till the Next. ... going to watch the S&J drop now... bye, see meeee. ⛏⚒⛏
On blasting across slips, I know the cast blasters in Wyo would try to put more than one cap/booster in each hole, timed to the same timing, but located on either side of the soft slip plane, to make sure each side would start/keep going.
Love your honesty in showing things going wrong. Your attitude is a breath of fresh air. No job is perfect. 👍👍👍👍👍🇬🇧
I spent a couple ore seasons back in the 1970’s working in an open pit iron mine. I was a blasters helper from time to time dropping 4-5 50 pound Monsanto charges down each hole and tamping them when they were loaded. We’d blow about 30 holes at a time and moved a quite a bit of material. It was a great time and a wonderful job that paid very well. But, as I said, that was open pit. If I would have had to put in time in the same conditions you guys are working in, I’m pretty sure I would have begged to do some other job.
I use a mould-able damp clay to pack off/ stem the drill holes after the holes loaded with ampho , works a treat in my mine , but I don't have water problems or slip problem. The clay really supercharges the blasts breaking power , this was a trick my father taught me that they used in the old coal& opal mines, might help you , but your local geology is way different to my gold mine here in Australia, keep punching men .
Thanks for sharing 👍
Yes, clay is way better for stemming, offers the most resistance. Slicing the sausages open and tamping in wet holes helps greatly. Minimum 2 sticks, when the water stops, load the rest of the hole with ANFO.
Your channel is unique, and not more of the same ol same ol.
I am looking forward to seeing you extract the gold from the ore that you just extracted.
You put plastic first into the hole, then you put sharp gravel 3-8mm that makes a plug in the bottom, after than you put stick. You should also try to drill downwards to make it easier when you have to plug the bottom.
A self loading micro dumper would be great for removing the pile.
You gotta remember, it is a job just getting the drill up the raise. Is there a micro loader under 100 Lbs.?
@@markmayer2029helicopter :)
@@DragonkinMetals You guys be crackers with your suggestions.
@@GodsBattleAx don’t drill downwards! If your ground is giving water your hole will fill up with water. drill on a very slight uphill angle and the water will drain out and it’s easier to pull out the steel after you blow your hole.
@@denisrowlett9829 You didn't understand.
Only drill downwards when you have to plug the bottom of the hole..
Water is not a problem, just blow it out with pressured air before loading it.
Have you done any blasting?
Love all the constructive comments for your viewers Jason! Outstanding community of viewers. Learning a lot and I will never put it into practice that I know of. Jason keep up the outstanding work and effort. Long time viewer and subscriber.
Thanks for showing this, Jason! It looks like you have alot of experienced hard rock miners who are following your channel! I see lots of what sound like good advice and years of experience in the comments. No other channel on RUclips has anything, even remotely like yours.. Well except Jeff's channel, too! You are a good man because many people wouldn't be willing to put their mistakes on video for all to see, much less appeal for advice.
a bore cam would be handy to see in the holes to look for problems
Yup, less than $20 bucks too
I spent a few years on a rock drill and a muck stick myself, now retired. Total respect for Jason & Harry! ⛏⛏
Wow! Now I get it. To be a successful miner, it is most necessary to enlist the assistance of an absolutely top-notch Mine Operator. Any ol’ body can muck all day. What counts is how ya deal with the never-ending variety of challenges and problems that mining surely provides.
I like how your blast hole density has shattered to the rock to an ideal size for your mini milling system. The slips and rolling of the vein is classic saddle reef, I'd expect the vein to roll into a steep fold limb, become much thinner. The grade of the steep vein ore zones was traditionally the richest ore. I suspect you have an asymmetric fold system, the crest/hinge zone has the nearly flat thick vein emplaced in the zone of maximum dilation which is what you have been drifting through. You're now entering the zone of rolling over into the steep limb. One of the nice things about these types of ore bodies is that the vein system can repeat several times as a stacked set within the fold.
Work fascinates me, I can sit and watch it for hours. AND I'm glad it's me sitting here watching you blokes instead of the other way around. Can't wait til you reach the raise and make life easier for yourselves.
Ya, I'll do fabrication and welding for a majority of the day, then come home and watch people cut trees down and mine in the evenings.
When you have a consistent slip back in there, once you recognize it, you want to focus on the burn. You can stem the back of the holes that went through the slip so the explosives are forward of the slip, and stem the front of the holes too. Don't drill any more holes than you need to for a good burn, and don't any more than you need through the slip. You can sometimes measure the depth to it. Load it with the most powerful explosives you have on hand. The goal is just to get a good burn. Basically what you did to fix the problem, but with foresight not to trust a bad slip to behave well. What starts badly usually ends badly.
You forgot the "making big ones into little ones" program.
@30:34, You can always Drill a relief hole at the bottom which wont be loaded with charge just for drainage.
Thank you for sharing even the mishaps. I don’t know anything about mining or minerals but I love your videos about it.
While what I am about to say is not seen by all miners as a realistic way of approaching this situation, the way that some professionals approach cracks in a face like that is to wash the holes out until mud stops running and then fill them with rapid setting cement.
The cement need not be super strong, because it is only there to act as sideways stemming.
Its job is to reduce the amount of cross flash between holes.
Other than that, one should actually get a whole lot of high shock stick and put in there.
When dealing with slips, especially where there is a very wide area of exposure, low brisance charges are less prone to clean detonations.
I realize that higher brisances also equals increased hazard, but it is one of the more popular ways to break past such gaps.
While I am sure there are other ways [I can actually think of a few], those are the most common, and most effective ones.
Thanks for sharing all. Learned a lot more than had gone as planned.
Upfront: I know nothing about blasting or mining, but how about placing stemming in the drilled holes when you know you have a slip in the back first, then place the explosives and finish off with stemming. That way, I think the gasses of the explosives won't shoot up the slip, but should stay contained between the stemming in the back and the front. I'm sorry if I'm being stupid or ignorant because I know nothing about mining whatsoever, just thought I'd share my simpleton idea.
And I'd like to use this moment to show my appreciation for you guys bringing this content online for me to enjoy! I could only wish to live in a place where I would be able to do something similar. THANKS!
What about putting bentonite in the hole to cement a solid hole before blasting. You might be able to turn the water off..
I also thought maybe drilling a hole just to let the water flow.
that was my thought as well - a slip like that is just another open end, except with the added "bonus" of being able to disrupt your other holes. Drybagging the anfo would mean you don't need to use stick powder for wet holes anymore.
if i had a passport i would take ou guys up on that job offer. looks like good ol fashion work. great video, thanks for taking us along! stay safe.
my days grafting like that are welland truly over, pain all over im worn out and only 50
Back when I was a coal miner, we had a similar problem, so the old man came up with a solution. We put dummies in and tamped them tight, then we set the powder and put the dummies in and tamped them too. Dummies were made out red clay. Worked pretty breaking the rock in those rolls. 4:08
I really love this series. Thank you for putting in the work to capture this on camera. -Colorado
There’s not ver many honorable people on RUclips. You sir are one of them. Showing mistakes is more important than successes. Making mistakes is how humans learn. 98% of content creators would have left this out and pretended they were awesome.
this is what makes us human, we make mistakes and learn...... unfortunately some mistakes just cost a lot more!!!
Hi Jason, Looking forward to the next video to see what the slip looks like. When I ran into water at our Nevada mine, we used florists putty - easy to use and it worked 90% of the time. Someone else commented about using plastic bags for the anfo - an excellent idea. Hopefully no more slips! Thumbs up! You and Harry stay safe!! Jim
Someone needs to do a montage going back over several videos of Jason's face just after he hears the boom when igniting the explosives'. Every time Jason "booms" the mine he can not hold back his grin. A montage of the different grins would be priceless!
"You load 16 tons and what do you get? Another day older and skinnier yet..."
Good song but mining is a good fun thing to do! It's my favorite thing to do!
Some good comments below, some not so much, the best one is cut off drilling at the mud and load with stick powder when wet. I know you were limited by supply but that was in your control. Keep it safe and simple. cheers
This is real world stuff, best TV in a hundred years. The good bad and the ugly.!!! Love this! We know Jason is so honest.!!! Reality!!!!!!! Thank you for this.
Always show the mistakes. Seeing how you overcome them is the good stuff.
Tiny bubbles in the mine makes you feel happy makes you feel fine love your hard work lads thank you
Jason, buy a button bit grinder! A hand held from Rockmore, Wilsonville, Ore. $1,000 plus a couple right size and shape pins.Grind the gauge angle back on a bench grinder. Don't hit the carbide though. You won't get stuck as much. Get ballistic pins and your drill will fly through that rock. Less rebound to the drill and your hands with a sharp bit.
Thanks for explaining all the details. It is entertaining and informative. Adding the video recording on top of the actual mining I'm sure is a pain in the backside.
Beats mucking out the milking stalls. No gold in manure.
All natural fertilizer. There’s gold there.
As my cousin says where there is shit there is money no truer words spoken
Lol in Australia we call plumbers shit wizards abracadabra a pile of crap turns into money
I'm the fourth to call bull shit on you. Lots of ways to make money on it. " If it can't be grown, it has to be mined".
Always show the problems too. A lot of us will be interested in them and in how you deal with them, and you'll get a lot of advice (some of it even from people who know what they are talking about haha)
I agree with what other people said about not trying to blast through slips, and in the future if you're in this situation put perhaps stem rock in the back of the hole so the blast doesn't get to the slip much.
Another awesome video. Great to see all the helpful comments regarding the blasting
love the above camera angle when drilling!! looks really cool and dramatic. Keep em coming!
What a saga! I'm really enjoying this adventure, especially because I don't have to do all the back-breaking work!
Thank you Harry for blowing bubbles through the steel for all of us at home who can't
Great video even if it all didn't go according to plan...watched every minute very interesting. Sorry I have no mining experience so I can't offer any words of wisdom but I'm rooting for you two. You both have a great work ethic and make a great team hope it all works out for you and you strike it big time! Thanks again.
Jason thank you for always showing the entire process both good and bad. Its paints a true picture of the labors of mining and what it takes to get the job done.
Excellent vid, really appreciate the honesty. I am a prospector with a couple of placer claims. It is great to see the other side of the fun. You two are real diehards. hope that shot went well. Looking forward to part 7.
I'm glad you decided to include the bad along with the good. We all need to see that things don't always go as planned.
Well. I admire your work ethic and tenacity. It’s always good to lean on your sense of humor when it becomes daunting
Wow. It’s so interesting hearing the multi-generational similarities and differences of the mine operations.
Great job you two. Thanks, Jason, for explaining where the vein moves. It helps us understand.
Can you roll up some stemming deep to block the slip side? Double stemming perhaps? Add some expanding dry grout they use for breaking rocks to your stemming mix. The expanding grout might plug off your water. Pack it with wads like black powder gun and let the grout do its magic. On second thought expanding grout might make heat and Ka-pow you :(
My thoughts exactly 😊?!?
I agree on using the expanding grout or roof bolt epoxy, otherwise if in mud, then drill/shoot the pattern shallow just to clear out. I wouldn't worry about the heat from the grout though.
It is illegal to use cement in the boreholes with explosives. It creates too much heat.
I appreciate you’re sharing this also, because those "production interruptions" sometimes happen, and we blasters must be able to fix and handle that in a safe and controllable way.
-Do you not use a booster charge for the ANFO?
Hope you get it sorted out, be careful.
-My advice is to pack approx. 50g of blasting dough/NG-base + blasting cap at the end of each hole to detonate the anfo that is visibly left. Good luck 🤞🏻
Your luck on that blast sounds like my luck I've had today. It will get better. I love watching y'all and what y'all are doing. Stay safe stay strong
Everything is easy....Until it isn't ;)
Good Job Guys !!
Much respect fellas, Keep up the great work, I hope you find that raise sooner than later.
My great grandfather repeated over and over, to his deathbed, if you're drowning, make a bigger hole. I think he was trying to say, when you have a bunch of water. Drill a bigger hole so you can load it heavier. Not sure if it will help, but he never steered me wrong. And after watching this vid, I think this is exactly what he was talking about. And it makes sence. Risking resources that never pan out. Bro, load a larger charge or 3.
I don't think you made a mistake. I know you drilled into an obstacle. Now you are dealing with that obstacle, bummer for sure. Great entertainment, though!!! Thank you both!!
glad to see my dumb traffic cone suggestion awhile back has worked out for you. for wet holes and anfo i'd do a thin slick plastic wrap ( like what i put over the windows in winter ) over the blow in tube that's sealed at the end. blow in your anfo and give it a twist to seal and then pack it in with the stemming. when the steel gets stuck in the mud of the slip, try blasting around the outside with your water hose. since the hole is bigger than the steel it might save you some beating on it to get it free.
i've never been a miner, but sometimes guesses from an outside perspective help.
Wow you guys just show how hard it still is to mine like this. Hope it all still makes you happy
Boy that drill is one hell of a machine! Good on you guys, tough work in there.
Jason making muck and work sound like four letter wor.......never mind!😊❤
In slips use a good backer like sand, cardboard ect pack it all the way in the back closest to the slips right next to that use ammonia (fertilizer) packecked in at least 3/4” per foot, then the next should be pretty routine you ampho, tnt or nitro ect whatever your main charge is when finishing up pack every hole with more packer material like fertilizer wadding ect and pack it tight carefully so you don’t damage your caps, wires, or det cord then fire in the hole
Thanks from Australia good luck stay safe happy days to all
usually with small hole blasting if you get to a slip with water and mud you drill less deep than the slip - if you get into the slip you first put stemming then explosives to not blow out into the slip
make a weaker shot to remove rock up to the slip - then use compressed air lance and pressurized water or clay spades to get to the other side of the slip - if necessary add some wall shaving charges to the next blast to expand the tunnel infront of the slip
if you got open pit mining conditions and have a drill bigger than 4 inches and drill vertically you just go a bit deeper and add more stemming - some load two blasting caps on either side of the slip without any delay or lay deth cord into the hole along the charge to bridge the slip if you drill into a face / vertical
cheapest is to just do a short blast, muck out clay and shave the walls
The way your voice-over started I was worried one of you got hurt.
To me it seems simple when you have a slip pack stemming first then your anfo and then stemming to seal. You guys are doing great keep up the exercise and you will be half the men you used to be! :)
Genuinly enjoy watching, You two make a great team. would love to meet you both. Need to buy another bag, bought two from last season has been fun going through them, not done though. Thanks.
wow that didn't work out just keep trying we all learn as you do.thank you for sharing the adventure and information
That fail is exactly what I warned you about in a previous comment. Your fixation on stemming did not help you when you ignored all the other problems. Centre prime. Collar prime. Drill all your non burn holes first to find the best ground and move your burn around accordingly. Would have been best to pull your cut up but honestly, hindsight’s a curse sometimes and I think almost everyone needs to learn the hard way or the lesson won’t stick. Take it as a lesson learned. Could have been worse. ANFO + water + voids + mud + shears/joints … if it had worked it would have been a minor miracle. I’ve seen fired faces with the paint still on them. What you had wasn’t pretty but isn’t all that bad since it seemed to have allowed the water to drain for the next firing. Good luck. For all I spend most of my time viewing your content cringing I have the utmost respect for you and your persistence, and I feel I would very much enjoy working with you. You are a true champion. Best of luck.
I would just say that where I am in Western Australia we use entirely different explosives, initiating and detonating systems so it’s an eye opener to see how you guys do it. ANFO is about the only common factor. So strange.
Pre-stem a lighter charge at the mud seam, then stem as usual. It should expose the seam to tell you more info about what's next. I've drilled and blasted rock with mud seams before and it seems to work the best.
Always shows problems and drama... it's good entertainment!
"excitedbox" has a great idea! I was thinking about pre making rounds using thin walled 3/4" pvc pipe. Seal the end, send in the wire and primer, fill it with ANFO, seal this end and viola. Make them ahead of time, and stop messing with the ANFO blower altogether.
I been following your channel for a long time now. Always interesting
Real dudes, working one of the hardest jobs in the world ❤
Chalk it up to a learning experience gentlemen thank you for sharing this with us six stars
Really enjoy your videos! Hope your paying Harry good; I enjoy watching you guys work. Always ready for more smelting experiments too! Thanks for sharing.
I don’t know anything about mining but I’m pretty observant to things that are happening…I’ve been watching you for a while. I think it’s cool that you did post this. It get a lot of eyes and ears on the situation. So on this particular blast I noticed that there was not a pause between the two different sounds of blasts like in your previous blastings… fingers crossed for a better out come on this round
Wow! It's easy to see that when it comes to mining, work is the word that matters most! ♥
I wish I could work with you guys for a year but I'm in a spot in life where I cant unfortunately. I hope you find someone who enjoys it just as much as you do.
A pair of large vice grips and a bottle jack to get the iron out of the hole would save you some effort. Thanks for sharing!
Been there and done that. Stuck drill steels and plugged air tubes. Dad often drilled 16 foot holes on his load claims. None of the new stuff you have in blasting. Just 40% TNT with electric caps. Deep holes, he layered the charges and mud. My job was cleaning the plugged air tubes and changing the bits.
if you have a problem with the slip, you can stem the slip up, and use a lot less stemming on the face. once the face is within a foot of the face, just drill right past it, and stem the slip on the other side of the blast.
Taking lunch always killed me. Lol
You boys need a radio or something to help keep your mood up.
They would get copyright claimed if they have “unauthorized” music in their vids.
You can make your own caps pretty easily. Also you cen increase the power of the anfo and sensitivity to a cap by adding a small amount of super fine aluminum dust to it, about a teaspoon full for every 5kg and roll it in a 5 gallon bucket till the grains are all silvery gray. Adding a thin plastic liner will stop the wet powder misfire issue. Also do be careful about wet slip fault areas as they might have lots of ground water behind them.😮
You guys are studs 500 plus buckets of mucking. Don't beat yourself up about the last blast. Things happen especially in slips with dumb clay blocking your drill holes. Look forward to see how this last blast went.
you are dealing with best guess behind the face. as they say shit can and will happen. Mr. Murphy always makes a visit no matter what.. Still doing a great job
When blasting with wet rock, you could try using plastic bags on the sticks when you stuff them,
That might help improve the blasting.
If i lived in the US i would love to do the mucking out. Great way to lose weight. Really enjoying the channel and cant wait for the next episode
The easiest and most efficient is stop at the slip stem in a little bit and blast to that depth Concrete in grouting, etc. etc. just takes more time and money lesson learned. That’s how you become a pro so I’d say you’re there now 16:09 you load 16 tons whadda ya get another day older and deeper in debt saint peter don’t you call me cause I can’t go I owe my soul to the company store…that’s a coal mining song but I think it fits lol back to the vid…. I have a sneaking suspicion you will lose your vein at the slip. Hopefully it will reappear at some point great video even though it was a bummer thanks for sharing. See you on the next one.👍🏼👊🏼
Thanks for the video. All that hard work and filming must b tough.❤
Thank you for sharing your failures with us, it's super important to improve the knowledge of everyone. The mucking is really a pain, so you should invest in an old pneumatic mucking machine, like you say the most expensive is the labor so it is a small investment with a big benefit.
good luck for the next.
