I'm on powder crew on a strip mine in Kentucky. We use ANFO as well with Dyno Nobel boosters and shock tube detonators.

That fine rock used to backfill the drill hole is called stemming. The purpose is to keep the explosives under pressure so that they explode outward and break the rock. Without the stemming, the explosives would just blow right out of the hole when they go off.

Knew of a company in Dublin Ohio that did road construction and mining work in Ohio and PA, I believe they may be long out of business, went to an auction at their Dublin location back in the 90's. they were selling off most everything. They had an ANFO truck and an explosives carrier truck for sale at this auction.

4:02 Three! Two! One! DESTROY!!!

Reminds me of my favorite bumper sticker... "There is no problem so great it can't be solved with sufficient explosives."

It's fun man, the guys working here on this blast love their job

I'm guessing the ANFO is delivered binary and mixed on delivery into the hole with the bagged NH4NO3 being a booster.

No it hasen't, I normally upload weekly. Thanks

I honestly don't know. Every shot is timed different

I use to work for this company was there during that blast that day. All of the product being used is Austin Powder. Yes, it is some of the hardest work around, but would do it again in a life. These are true hard working people.

Did anyone else see the det-cord go off right before the first explosion at 4:04?

Thanks for uploading!

first hand watched a many shot set off....even in the cab of earth moving equipment would shake as the shot went off....nice filming.

No, there are no explosives exposed on the surface

And you guys have such a different way of loading the holes... I'm Australian, here we just get 150 or 400 gram boosters, connect it to the leads, then just pour the amount of Ammonium Nitrate over and stem it... Do you always put AMFO in over the det ?
