Love to watch the path of the blasting cord as it streaks from hole to hole. 1/10 to 1/20 of a second from start to finish even with a delayspectacular.
Thank you, i found out later that water floods the bore holes sometimes and that will cause an incomplete reaction once its detonated resulting in the red nitric oxide smoke.
thanks,I found out it most often occurs, that is, lots of red smoke, when groundwater leaks into the bore hole and is present w/ the anfo when detonated.
I haven't found a prep video on mine demos. Is it cheaper to do this than those witengen grinders? Its gotta take time to drill all those holes and drop the boom boom mix down them...
@@markobora6860 When do they decide to blast vs just have an excavator dig? Or does blasting speed digging up considerably because no excavator is involved, just a loader? How deep does that blast go -- what's the effective 'softened ground' depth.
So every jobsite or " shot" is different as far as the depth go. Usually you need a minimum of 10ft of hard rock to blast. Rock quarrys usually blast anywhere from 20 to 60ft holes. When you blasting for say a pipeline or finish grade for a road or building. The depth will say be written on those wooden grade stakes. The reason they dont use and excavator is because the rock is too hard. The excavator just scrapes the hard rock but doesn't acually do anything to it. So they use explosives to break it into smaller pieces so an excavator can then move it
And if its soft dirt or soft rock that an excavator can move on it's own you dont want to blast it. If you blast just soft or loose rock it's going to sling shit all over and can be very dangerous. Plus it's very expensive to drill and blast somthing an excavator can just dig up....you only blast solid rock
They start tracking the machines back into the work area immediately because they were removed to a safe distance so they would not be damaged by flying debris. It could take a day for a dragline to get back to work but the crews would still be very busy during that time.
I was the loader man and I went back as soon as the shot was pulled and the all clear given and started cleaning the outside up from stray rocks so the trucks could get to the shovel and not cut tires.
We need more bridges interstates and highways in bluefield West Virginia we need more bridges interstates and highways in Princeton West Virginia we need more bridges interstates and highways in Beckley West Virginia
Looks like there was not enough room for the rock to break out , The blast started from the left, the rock basically ran into itself. Being in an open pit, im sure this was by design. They set the delays as fast as they could in front of the blowout.
That is a beautiful work of precision art. Very enjoyable to watch. Thanks for sharing.
Love the ones that are so controled they just shake the dust off the surface. Master work!
Nice shots. Been drilling for a few years now. Always enjoy a good show
Awesome FOOTAGE!! Thanks
This is an underrated video and deserves more views!

This is very satisfying to watch
VERY good shots! A-PLUS!
Those chain reactions are so damn cool
Magnificent
It seems like there is always that one hole in a sequence that has to explode like a volcano instead of staying underground like the rest of them.
Air
good pay
great video! Can You guys explain what the red smoke is when the charges are set off? Is it nitric oxides formed during the detonation?
Thats right, that is NO2, it forms because the high level of oxigen anda are ver y bad, steal energy and they are ver y toxic
russian-blasting-videos-have-lots-of-red-smoke---bad=technique?-or-just-lots-of-water-in-blast-hole?
I was told it was from moisture and the anfo

Nice job!!!!!

Most hatd rock mines those grinders would just chew themselves up and not break any rock.
What are those electrical flashes prior to explosion, it that some sort of flash / tracer fuse or something?
That is blasting cord, detonatipng fuse

Miner porn. Weeks of work for 10 seconds of fun.
1:23, Looks like a lot of orange smoke. Water in the holes?
Tres intéressant

It almost looks like water in most cases
that' awesome. like it
How long does it take the dust to settle?
20 minutes tops. Then you get back to work and move the rock/ore you just blasted.
Haha. Not much of a break!

Not long. We always walk the shot and give it a once over before tracking the drills back online.
ไม่ปล่อยน้ำก็ท่าข้ามจมแหละ
That was a blast.
What next after the explosion?
Clean up any fly rock with a loader or rubber bull, then move a shovel or loader in and start digging.

Is there any specific reason why the charges are not always configured in a shortest-path detonation sequence?
the purpose is to focus the explosions down into the rock, so theres work done on the best sequence to do this.

2:30 a bit heavy handed loading the oversize.
bah, nothing around, you don't wanna drill and blast that shit twice.

What are they mining here at this site. Maybe it's a training site for future explosive technicians. Making sand for the fun of it.

Where's me shovel ?
Equipment is moved away a safe distance on blast day. At our mine it's 1000 feet for equipment and 2000 feet for people.
