Thanks Roger, I always get 1 or 2 in the first Hour as sour grapes from local competitors, 3 of those 5 are in the last few hours... RUclips must have started promoting the video to the rock huggers.
Wow, that blast was spectacularly, unspectacular...really well controlled! 😎 EDIT: Just watched that digger plucking the rock from the soil like a huge mechanical bird...very cool.
It was light on for cover as we were running out of easy to reach soil... I did move my Hilux a bit further away for this one as it was only 1 meter on the other side of the fence, all good though as nothing went over the fence.
The small size of the excavators I see on your job is always somewhat of a surprise. I'm from Canada. Theses small excavators are mostly relegated to jobs where there is site access restrictions, foundations repairs and landscaping. Any new construction would be done using a much larger machine. I guess that with the short building season, size does matter for expediency's sake. It is also true that the holes we dig tend to be deeper as we do need to get under the frost line.
We need bigger machines to break through frost and extend our season. That little excavator also is cheaper to move around. Cheaper for truck and trailer plates. Also oversize fees and weights.
Looks like *Australia* is the place to be if you want to build a garage with a /very/ solid base to pour a concrete plinth for a really nice engine lathe. Thank you for taking us along on your adventures!
I have to say Dave, you Australians have the nicest boulders, That first shot was a little more spectacular than usual. Thank you for making your hard work to look like fun, I am just joking, you are one of hardest working men I ever seen. ... :-)
"might have been a tad heavy handed", combined with a mildly uncontained shot 1, great shatter and great bulking of the material earns this an 8 out of 10 on the patented TC's "That blowed up real good" rating scale. Nicely done.
My dad was a land surveyor up North. Once he blew up a beaver dam using three sticks of dynamite super instructions. However the person who said three sticks meant 6 inch 1/4" diameter 40% power sticks. Dad got three sticks from the road crew that was blasting rocks. Those sticks were 18" 1/2" diameter 80% power. He blew that dam down to bedrock.
Hello Dave, Happy customers are the best! Great job - as always! Just curious - on the whale rock - how long did it take to drill one deep hole in real time? That Granite can be nasty hard! Take Care, Stay safe! Jim
We had to excavate around 200m³ of granite for our house. (Blackwood forest) Luckily only 1/4 was really hard, but it took around 1 week to Chisel that out with the big excavator. Using detonations isn't easy anymore, you need a specialist, a lot of paperwork, evacuating half of the town...
Good one! 👍 Would be interesting if those rocks could talk. How and where they formed and how they came to be there. Little did they know what fate would befall them! 🤔
That is really interesting that you say this Michael, other people with a similar ideological profile to myself have also noticed this. All my recent videos can be found here - ruclips.net/user/DemolitionDaveDrillingandBlastingvideos
Looks chilly there! We were 110F with the heat index today. Humidity has been horrible here lately! Do they do anything special with the busted rock or is healed off to a dump site??
Got to say, the amount of construction happening in this geographical area is HUGE &! the amount of rock I see sifted through the buckets of the machinery & loaded into piles 8 - 10 ft high all around the edges of the landscape is absolutely immense. One site I've been watching, it's been 8mnths & they STILL haven't finished. If YOU haven't been part of it, I'd be mighty surprised.
All of the rock around Mernda is just basalt and most of the time they just bash it out with huge excavators because many construction companies are fearful of blasting and would only undertake it as a last resort. Thanks for watching.
Thanks for asking MT, I think you are referring to a water flushing drill as used underground?? I did persevere with these for a few years when I started to take stone dust safety seriously. I found that this solves part of the problem but also causes more exposure problems and creates new issues to deal with because of the flooding and slurry build up etc.. When you are air flushing and using a powerful drill and a sharp drill head you get lots of large size stone chips flying out of the hole and only a small portion of the total dislodged mass is the nasty micron size stuff, by comparison when wet drilling with slow flowing water as a flushing medium, it seems that everything that exits the drill hole is crushed to oblivion - micron size. This might be OK when working deep underground in very damp conditions but on a warm day on the surface this slurry that you tend to get covered in, quickly dries out and then becomes airborne! additional to this problem when I'm using soil to cover the blast - which is often recycled many times... and heavily loaded with this now dried out micron sized granite slurry... you can see that there is a potential problem here. The method that I'm using at the moment with the HEPA vac works fairly well but I'm always looking for new ideas. Thanks for watching and contributing.
@@demolitiondavedrillandblast That makes some sense, at least with the slurry that gets on clothes and equipment. Do larger chips help drill bit life or speed noticeably? I imagine much underground drilling is horizontal so the chip flushing is better. However for the soil cover, most soil has a substantial fraction of micron size stone particles, several percent by weight, generally classified as a fine silt or clay in soil texture analysis. (In texture classification clay is bluntly defined as any minerals less than 2 micron, ignoring the actual electro-chemical charge.) Maybe the stone dust needs some amount of time to bind with other soil components.
"Do larger chips help drill bit life or speed noticeably" - Yes both, air as a flushing medium gets the big chips up and out of the hole quickly, when you are using water the flow rate is very much slower (so that you don't have to deal with so much flooding) and as such everything get pulverized - waisted energy and extra wear. Why have you not posted any videos???
@@demolitiondavedrillandblast Because I just take take take. Also I can't afford a camera and my phone is old and barely functional, just had other priorities for the last few years.
Very good question Mark, I don't think any of the current theories fit what I regularly see. I often see rocks that have rounded edges on all sides and yet have tight fitting joints, with wear curling down into those joint planes. I should really be taking pictures of this.
Take a look at Joshua Tree National Park in California, if you'd like to see a similar formation in weathering granite. The stones you're finding perfectly fitted together are probably weathered pieces of continuous bedrock that were separated by cracks .
How long to drill a meter deep hole in your average granite boulder? How do you go about estimating the time a job will take just on the drilling side?
The first blast was all good, the second blast had one hole in the rock up near the front fence go through when I was drilling, that was OK because I stemmed it up prior to loading and that worked OK. The other rock was OK when drilled but broke through the bottom when fired and left a big chunk of unbroken rock and what looked like it could have been a missfire. I carefully removed the stemming to investigate and found the blast had broke through and made a huge cavity underneath. A new and shorter hole was drilled and fired to break this bit up.
Big Dave, I’ve seen some blasters shoot rock and covering the blast with a big rubber mat, like strips of old tires (or something). Seems easier and faster, but not sure of your rules in Australia.
I was wondering that myself, but then I thought, Dave would need a bigger vehicle to move them around, and they don't really help Dave they help whoever is paying the excavator to move the dirt around.
Yes, I have a heap of these Michael, I need to bring them to the job on a truck which costs money, the soil is already there. The soil also gives a higher level of protection and cuts the noise down drastically where the mats do little for the noise. The blast noise brings complaints and spectators that I don't need.
Ahab Dave puts the hurt on Moby Dick Granite, and some of it`s little friends. I will agree with David Handley`s comment, Dave does work hard for his money, but Aussies are a tough breed, and are no strangers to hard work. Thanks for another great video, Dave, and be safe. Cheers.
It appears to be an igneous rock but I doubt it is dolerite. Dolerite tends to have iron in it which turns the soil around it red when it decomposes. The rounding can be caused by glaciation, river erosion or decomposition due to acidity in the surrounding soil. But in this case there did not appear to be decomposition.
The harder the rock, the more unforgiving it is when you load it a bit more, hence the gravel in the bottom. 😃 If we can use the blasted material on site, we do it on purpose to have smaller fractions, or we run the material trough crusher bucket on the excavator. The only measure is a happy costumer 👍😉
@@goodiezgrigis , ive just spent a couple of hours checking these things out and i now need a cold shower. not for every job but boy oh boy what advances in technology. some of them dont seem very well thought out. if i can see behind the crusher mechanism you can count on stuff snagging in there. when i started in an excavator, rake/sorter buckets were just entering the scene.
The knock on button bits are mostly LHS Rock tools, made in China, good quality.t The drill rods are Atlas Copco / Secoroc / Epiroc. they are so much better than the rest, that is is worth paying the high price
Welcome Aubrey, don't generally use those for breaking rocks, expensive, inefficient and extremely loud. Only place that I have used similar approach on rocks in dislodging rocks that might slip down onto a road way from way up a hill - far to difficult to get a drill up there.
Did you ever see the rocky and bullwinkle show where they had the silent explosive? Probably a late night can’t sleep thought, but the expando stuff you use, could it have been used during the Cold War to demolish concrete structures silently? Yea, I know drilling holes silently is almost impossible but wet grinding with the right type of drill might work well enough. Just makes me wonder about Cold War stories of silent explosives. It turned up on get smart too I think?
@@demolitiondavedrillandblast its nice to see such Good rocks going to good use and its double bubble for you since you get to sell them AND you get paid for the job not to mention you also get paid for YT its like triple bubble payment
@@DatBoiOrly I doubt Dave is responsible for disposing of the rock. I would think it would be the responsibility of the general contractor to remove it.
Dave to the rescue... certainly an impressive and huge "whale".... 1.8M is pretty deep drilling. Your drilling gives a whole new meaning to ''getting a leg over" LOL. :) Nice job as per.
Pretty cool! On the whale rock did you set timed/sequential charges to take off the perimeter first? Seems like the smaller 9-charge rock was all at once.
Turkey and Syria that were hit by a huge earthquake, reporters said it was like the cities were bombed from underground. After seeing this even small explosion I understand why so much more now.
Do you think the developer coated this block with extra soil to disguise this? Seems in some regions you need to walk your block with a steel probe before putting money down.
Dave, while I understand it's hard to have the timing perfect when shooting time lapse of the drilling, the drill bit you showed was so fast we really couldn't see what you were showing. I'm guessing a dull bit.
Wow, that first blast was (almost scary) violent sending big pieces of granite out of that mountain of dirt. Was that what you expected to happen or was it a matter of too much explosives (nah, I don't think so) of not enough dirt? Speaking of the amount of explosives; how do you know how much you need?
Hi Rob, I expected that it might throw a little bit - we moved our vehicles for this one, a case of would have liked a bit more dirt but were running out. A small amount of soil came out of the hole but nothing left the site. Knowing how much bang is required comes down to the ratio of Grams of explosive per cubic meter of rock that needs to be broken and a fair bit of experience.
yes... my axera7 was allot easier than offsiding a rise miner...we couldn't use the leg cause we were sinking a rise ...guess whos job it was lean on it with a 3 foot steel
@@demolitiondavedrillandblast oh I’ve used them. Slab jacking concrete crew screw ups when it’s not worth breaking it up to re pour it. I tend to agree though. With a big drill you’re never going to learn intuition about what gets production out of the machine for the type of rock you’re in. When you are holding the toll you can feel what’s going on and learn.
@@demolitiondavedrillandblast excellent work though. Got it all down to size for the equipment available to muck it out, didn’t send any fly rock anywhere, much less anywhere near any of those houses!
oh man, did you count cut that granite on slides/tiles? Man, it cost a lot of money to order some for ladders, entrance tiling, kitchen boards etc. You could tile you bath/shower, garden. Not sure demolition cost less.
@@demolitiondavedrillandblast Just try to find some company with its own terrytory and proper tools. All you cost is to cut-blow down sides to get big stone, load it and deliver it to that company.
Is there such thing as too much breakage? - Not really, some guys tear up a bit if it is really smashed up and they had planned to on sell it for landscaping etc. and it makes it near impossible to sort and thus more difficult to dispose of. Primary objective is to make the pieces small enough to be manageable for the size machine that is digging it out.
Good question. Yes, I have a heap of these Frederic, but I need to bring them to the job on a truck which costs money, the soil is already there. The soil also gives a higher level of protection and cuts the noise down drastically where the mats do little for the noise. The blast noise brings complaints and spectators that I don't need.
Why didn't they just lift them out? Drill holes, add anchors, lift out with small crane, sell granite stones to be made into counter tops or large landscaping rocks.

The rounded weathered look of the rocks suggest that there was either a river or beach there once.
Yes, certainly. Interestingly though I often find these rocks with rounded edges tightly locked together like they are carefully fitted.

@@goodiezgrigis , ive just spent a couple of hours checking these things out and i now need a cold shower. not for every job but boy oh boy what advances in technology. some of them dont seem very well thought out. if i can see behind the crusher mechanism you can count on stuff snagging in there. when i started in an excavator, rake/sorter buckets were just entering the scene.
Dave, you are the man.
What an awesome video, thank you. What brand of boring bits do you use?
The knock on button bits are mostly LHS Rock tools, made in China, good quality.t The drill rods are Atlas Copco / Secoroc / Epiroc. they are so much better than the rest, that is is worth paying the high price
@@demolitiondavedrillandblast thank you for the information, I love the channel
Drill holes and connect the foundation with rebar to the stones? Would that be a problem?
These stone would block the hallway on this home.
Love the video new to the channel do you ever use RDX cone shapped charges for stuff like this?
Welcome Aubrey, don't generally use those for breaking rocks, expensive, inefficient and extremely loud. Only place that I have used similar approach on rocks in dislodging rocks that might slip down onto a road way from way up a hill - far to difficult to get a drill up there.
@@demolitiondavedrillandblast I appreciate the response! Happy blasting
Wow. I guess these folks really wanted a house with a basement!
Yep.
I'm curious. Is there any concern that one or more of the individual charges didn't fire before you go digging into it after the blast?
Always a concern 66, we have ways to manage this.
You are the man 👍👍awesome Dave.
Thanks Bob.
Did you ever see the rocky and bullwinkle show where they had the silent explosive?
Probably a late night can’t sleep thought, but the expando stuff you use, could it have been used during the Cold War to demolish concrete structures silently?
Yea, I know drilling holes silently is almost impossible but wet grinding with the right type of drill might work well enough.
Just makes me wonder about Cold War stories of silent explosives. It turned up on get smart too I think?
No, I recall that episode Bruce, A diamond core drill is not noisy.. but slow and expensive to run.
What happens to the rock when it removed from the job site, would any of the stone masons be able to use it in monuments
All of this rock went to a guy that supplies landscapers.
@@demolitiondavedrillandblast its nice to see such Good rocks going to good use and its double bubble for you since you get to sell them AND you get paid for the job not to mention you also get paid for YT its like triple bubble payment
@@DatBoiOrly I doubt Dave is responsible for disposing of the rock. I would think it would be the responsibility of the general contractor to remove it.
You need to make a seat for that drill lol, that way you just sit and drill away 😂
Couple of nice shots mate
Thanks Skeets.
How many people caught the rainbow in the background when the excavator started filling in around the rocks
Dave to the rescue... certainly an impressive and huge "whale".... 1.8M is pretty deep drilling. Your drilling gives a whole new meaning to ''getting a leg over" LOL. :) Nice job as per.
Thanks for watching Chris.
I would love to see clearly step by step making connection before blasting
Probably won't see much of that on this channel.
i would love to watch them dig it out the rest of the way . great video by the way
Yeah, I can watch it all day Noah.
Pretty cool! On the whale rock did you set timed/sequential charges to take off the perimeter first? Seems like the smaller 9-charge rock was all at once.
All of the holes were timed with 17m/s between the holes.
@@demolitiondavedrillandblast What effect does the 17ms delay between holes have? Why not set them off all at the same time?
Turkey and Syria that were hit by a huge earthquake, reporters said it was like the cities were bombed from underground. After seeing this even small explosion I understand why so much more now.
That's gotta be such a satisfying job!
It is James.
Next you will be adding a chair on your drill. Ride it down.
That first shot puffed a little but it did the job. So the contractor is happy
Everybody is happy.
job well done, Dave! 👍👍👊👊
Thanks JW
Do you think the developer coated this block with extra soil to disguise this? Seems in some regions you need to walk your block with a steel probe before putting money down.
That may have been a good idea.
Not too shabby for an old bloke Dave(u prob younger than me). Once this blasted covid slows down i can get to ur place....
Don,t hold your breath Jase.
@@demolitiondavedrillandblast sux....
Dave, while I understand it's hard to have the timing perfect when shooting time lapse of the drilling, the drill bit you showed was so fast we really couldn't see what you were showing. I'm guessing a dull bit.
Hi Jaqui, I was showing how it was new and sharp actually, I held it up for about 10 seconds but that was not long enough..
Wow, that first blast was (almost scary) violent sending big pieces of granite out of that mountain of dirt. Was that what you expected to happen or was it a matter of too much explosives (nah, I don't think so) of not enough dirt? Speaking of the amount of explosives; how do you know how much you need?
Hi Rob, I expected that it might throw a little bit - we moved our vehicles for this one, a case of would have liked a bit more dirt but were running out. A small amount of soil came out of the hole but nothing left the site. Knowing how much bang is required comes down to the ratio of Grams of explosive per cubic meter of rock that needs to be broken and a fair bit of experience.
I’m glad the only drilling and blasting I’ve done was with a cab drill and a tamrock and not a woodpecker!
yes... my axera7 was allot easier than offsiding a rise miner...we couldn't use the leg cause we were sinking a rise ...guess whos job it was lean on it with a 3 foot steel
Every good driller has started out on a sinker or an air leg.
@@demolitiondavedrillandblast oh I’ve used them. Slab jacking concrete crew screw ups when it’s not worth breaking it up to re pour it. I tend to agree though. With a big drill you’re never going to learn intuition about what gets production out of the machine for the type of rock you’re in. When you are holding the toll you can feel what’s going on and learn.
@@demolitiondavedrillandblast excellent work though. Got it all down to size for the equipment available to muck it out, didn’t send any fly rock anywhere, much less anywhere near any of those houses!
Top work as always.
Appreciate that. Thanks for watching
Silly question (?)... what happens if there is a mishap and some of the explosives don't go off ?
I have to find it and make it safe, there are set procedures for this.
@@demolitiondavedrillandblast Thanks!
Could see the start of a rainbow curving down onto the old pot-o'gold ie your work that front rolling through for the 1st blow. Did you find any?
oh man, did you count cut that granite on slides/tiles? Man, it cost a lot of money to order some for ladders, entrance tiling, kitchen boards etc. You could tile you bath/shower, garden. Not sure demolition cost less.
I have been thinking about building / buying a diamond wire saw for just this purpose.
@@demolitiondavedrillandblast Just try to find some company with its own terrytory and proper tools. All you cost is to cut-blow down sides to get big stone, load it and deliver it to that company.
@13:38 - Is there such thing as too much breakage? You advised that you may have been heavy-handed with that load. Could you explain maybe?
Is there such thing as too much breakage? - Not really, some guys tear up a bit if it is really smashed up and they had planned to on sell it for landscaping etc. and it makes it near impossible to sort and thus more difficult to dispose of. Primary objective is to make the pieces small enough to be manageable for the size machine that is digging it out.
Why don't you use regular blasting protection matts made out of old truck tyres, instead of covering the stones with dirt?
Good question. Yes, I have a heap of these Frederic, but I need to bring them to the job on a truck which costs money, the soil is already there. The soil also gives a higher level of protection and cuts the noise down drastically where the mats do little for the noise. The blast noise brings complaints and spectators that I don't need.
@@demolitiondavedrillandblast Okay, Thanks for this info and taking the time to explain this to me, much appreciated. BRFG
And that is the day you remember you actually wanted a house without a basement! lol
Awesome thank you
Thanks for watching 123
Ever use Dexpan? But the earth moving explosive is cool.
Used a similar product today and also last week, video coming soon.
This looks like a fun job.
It was!
Why didn't they just lift them out?
Drill holes, add anchors, lift out with small crane, sell granite stones to be made into counter tops or large landscaping rocks.
If it were that easy they would have.
Boom goes the dynamite. Nice job.
Thanks for tuning in Sonny
Dave . With that hard granite , would you have to use a very fast reacting charge ?
Not necessarily Bob, the faster the VOD, the more shattering action you get but you can break granite with Black Powder.
Great job DemoDave, can I ask how much does it cost roughly to do a job like that?
Private message me and I'll tell you, find the email contact on my web site.
About 5k roughly
