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?
@urielmendoza1311

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
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.

@@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.
@ejahtretzen9261

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

the purpose is to focus the explosions down into the rock, so theres work done on the best sequence to do this.

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.

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.
