- This is what happens when a mining company tells you it's "Stone Blast Day" and asks you if you want to shoot it with the Motion Amplification camera. Obviously, we said YESSS!
I have no idea what i watched
But it was satisfying
here from steve mould
Veritasium and Mr. Mould
same bruh
I wish this was open to the public to at least test
You’re shocked to discover a big ol’ blast of rock shook the road right next to it?
😂
:D
i think they are just trying to be enthusiastic and are more excited about the fact their system makes it easily visible
@@joshieeee20 you fuckin hero you
Most people don't understand how this camera works and what is being shown. It only updates changes in pixels, so it can have a much higher frame rate. E.g. detecting movement of areas away from the blast, which would be extremely hard to measure with a normal camera.
Good blasters care about vibrations and flying rock debris. They care about their neighbors and the environment. They learn from every blast so next one will be even better. It was interesting to see the micro-motion in road behind blast. Something hard to plan for is wave energy refraction and stronger standing waves.
Good blasters tightly control the whole process: drill right depth, hole spacing, hole diameter, type of explosive, type of detonators, time delays on detonators. Even before that, Geologist has performed a survey, and prepared blasting plan. And good blasters don't waste explosives by using too much, or too little.
I have friends in quarry business. They have done so many blasts, they use a 'cookbook' of prior blasts. They have a good idea when doing next one. They don't waste time and money on bad results.
Great explanation. Thank you 🙂
@@bobcaygeon6799 Thank you for comment. When I first saw the caption about Motion Amplification, I was clueless. I did some research and it is a real profession using specialized video equipment. The camera and software freeze frame, then compare with last frame, and so on. They end up with very detailed video showing tiny movements. When played back it is obvious vibrations are occurring. This can lead to early fatigue fractures in structures.
I have been interested in blasting and implosions for a long time. I met a company in Midwest with several quarries. They post fun videos of their 'work'. I would call it 'play', but there is lots of hard work done ever before pushing the button.
A blast relies on vibration that is what fractures the rock.
A geologist is a scientist who studies the solid, liquid, and gaseous matter that constitutes Earth and other terrestrial planets, as well as the processes that shape them. Geologists usually study geology, although backgrounds in physics, chemistry, biology, and other sciences are also useful. Field research (field work) is an important component of geology, although many subdisciplines incorporate laboratory and digitalised work.
Geologists work in the energy and mining sectors searching for natural resources such as petroleum, natural gas, precious and base metals. They are also in the forefront of preventing and mitigating damage from natural hazards and disasters such as earthquakes, volcanoes, tsunamis and landslides. Their studies are used to warn the general public of the occurrence of these events. Geologists are also important contributors to climate change discussions.
A blast engineer creates a drilling pattern. The pattern is drilled out. It is then handed over to the shot firer who is in charge of loading the pattern timing and the blasting of anfo. Drilling and blasting currently utilizes many different varieties of explosives with different compositions and performance properties. Higher velocity explosives are used for relatively hard rock in order to shatter and break the rock, while low velocity explosives are used in soft rocks to generate more gas pressure and a greater fracture of rock.
@@Tangaroa775 Thank you. I have great respect for Geologists. In college I took a number of geology classes. It helps me better understand our physical world.
Looks like the blast pressure was distributed in an inverted bell curve, or horizontal hour glass ⌛️
I think I see what we're supposed to see, it was mighty mouse right?
This would be great in the semiconductor industry as any vibration is very much disliked.
Ground : damb an I was just getting settled in
That was interesting!
Very interesting. the type of charge determines the shock wave?
Planetary applications from satellites
In the perfect blast the surface does not move much at all.
Is this the quarry along the thruway near Buffalo?
Very, VERY cool.
Cool footage well executed...
Love to ha been near to feel it....
Thank you for posting that! Very interesting to watch.
So...motion amplification screws up the video until it looks like a scene from the old Blob movie.
Anymore great ideas?
Take That ! you f#(! ing ROCKS !
is it not the camera that is moving, rather than the ground?
At the moment of explosion there is indication of movement on the road due to the explosion. There is no indication of movement apparent in the hill in the background of the shot. If the motion was due to the camera moving everything in the shot would indicate motion. In addition it is highly doubtful that this camera detects variations in reflection of light slower than the shockwave through the ground.
Let's see, the shockwave through the earth would probably take at least 50 ms to cover the quarter mile between the blast and the camera, but with the video being slowed down by a variety of rates, and no timestamps to show real time, it's a bit hard to tell exactly when things happen. Certainly any immediate movement won't be due to camera shake, but I think some of the apparent motion a bit after the blast could be.
I'd expect any camera shake to be amplified uniformly by the motion amplification as well (i.e. it would affect everything in frame).
It's not the spoon that bends, it's your mind.
does this help in planning next blasting??
probably NOT
Very interesting indeed.☘️👍
Here from "um actually" YT channel
Maybe the next blast due to the reverberations. Ran laterally...
Less explosives smaller particulate
That's what I thought at first. But, the explosive is distributed uniformly and the smaller pieces were at the ends. Looks like the intensity was boosted by the shockwaves reflecting off the ends.
Probably solve it by timing the charges from the outsides, in.
I have no clue what I'm talking about.. lol
There was a river there, with fish...
WAS
mining for gold.
Can you do this again but with a building, say... the Kremlin?
No, the rebellious region known as Ukraine will certainly look like this soon though. Приветствую тебя, "товарищ".
