Josh, here is an example of a blast in an open pit mine in Mexico. It did not go well. Each of those black geysers of blasted rock indicates a poorly set hole and sloppy wiring of the electrical connection which caused many of the blast holes near the face wall of the blast to not detonate at all. Now the work is much harder to complete and will take them a lot longer to detonate, not to mention the extreme danger of having men wander over a blast field that is wired to explode. All it will take is Wilkie talkie transmission at the wrong moment to set off the remaining high explosives. I only saw a couple black geysers in the shots grandpa Bud laid out and detonated. His shots all detonated. The guys in Mexico that work the detonation field make about $1.50 an hour. Dad

No the geysers as you call them are just poorly stemmed holes.

Muchos gases naranja y amarillos. Deberían utilizar otro explosivo. El ANFO ya pasó de moda. Las emulsiones son las indicadas. A largo plazo sale más barata el drilling and blasting. :)

He was asking why there was also a row of explosions over on the far right, which was a reasonable question that I had asked myself. The reason for the blasting on the far right hand side was to cut in a drainage and rock fall channel against the pit side wall to protect the haul road.
@lewiemcneely91436 жыл бұрын
It's called a pre-split to get the full force of the explosive against the wall to make a clean shot and a smooth face. If it was out in the open it'd just blow out and have rocks hanging all over.
@celluskh60096 жыл бұрын
What a bizarre series of 'answers'. There is clearly a space between the blast and the road left clear - why? The pre-split has nothing to do with drainage. It is solely to protect the wall.
@lewiemcneely91435 жыл бұрын
@@celluskh6009 They probably can't shoot but so much at a time. Here they monitor the shock wave of the shot and have limits you can't go over. Federal MSHA stuff. The shots here would run close to 92K tons and we'd run it in 2 weeks when running regular. And you only worry about drainage on the floor. The bench takes care of itself. And the pre-split is the wall face after the shot is hauled off. Then you scale the loose off it and drop down to the next level.

what's the clearance time like considering the NOx gas level in the pit after blast.
@samvimes10835 жыл бұрын
All depends on weather conditions, 80-90% of blasts will clear their fumes to safe levels in 15-30 minutes. Summer is typically better as the heat drives convection currents to clear the pit rather quickly even if there's not much wind. In Canada, where I work, temperature inversions on calm winter days can hold NOX and SO2 fumes in the pit for hours. Sometimes, though rarely, it will shut the pit down for an entire 12 hour shift.

Why did the pre split face go before the block?surely you heave the block first then the pre split into it!
@mccallan27983 жыл бұрын
@@badensmith737 Nope, other way round. Pre-split is just that. It's done first and the aim is to create a "crack" between adjacent holes in a line. Huge blocks of solid rock are split by drilling a series of (normally) equidistant holes and then inserting "chisels" (called a feather and wedge) into the holes and tapping each successive "chisel" deeper into the drilled holes. Eventually, the lump or slab of rock will split neatly along this series of holes. This technique is more of an art than a science. The pre-split in the video attempts to do something similar but, unlike the solid piece of rock I referred to above, the rock in the face will have plenty of natural cracks that the "shock" of the explosion will dissipate into if you don't keep a significant mass in front of the holes in your pre-split line. You definitely don't want to heave anything anywhere. The hole in the pre-split are normally charged very differently (lightly) to the normal blast-hole. www.minesurveyor.net/ssblastimages/smoothhighwall.jpg

Exactly as intended. Everything to the right had been drilled but not loaded. That area on the far right that went is called a "pre-split" and is a single row of holes at the final intended wall to serve as perforation, basically, for the next blast.

@gragor113 жыл бұрын
@@crsf29 I'm surprised they pre-drilled the shots not fired. My experience is underground. If I did that I would probably wind up with cut off and blocked holes. I suspect they can get away with not having too many holes fouled due to the physical size of the holes. Perhaps they adjust the spacing between the blast areas leaving the distance between the soon to be leading edge holes greater as it would act as a bit of a buffer for the hole and the extra burden wouldn't matter as soon those edge holes would be first to go in the next blast.
