I routinely witness ANFO explosions in mining. I think most “experts” under rate the power of it when it is wielded in the hands of guys who do it all the time. Mines routinely move 1,000 tons of overburden with a ton or so of charge. Very impressive stuff.

"Mines routinely move 1,000 tons of overburden with a ton or so of [ANFO] charge."

I agree -- BUT those charges are confined within boreholes -- in direct contact with the material they are "pushing around".

They are not acting via air blast coupling -- at distances of over 50 feet -- to selectively pulverize small sections of concrete (leaving the intervening surfaces undamaged).
