Figure half pound sticks ( 7 oz standard) that's 1400 sticks of dynamite, which is a hellalot. Usually use 2 caps per bundle of dynamite, in case one is bad, the other will go.
Don't say whether caps are electric or lit fuse variety. Probably electric, since no det cord listed as missing, and most commercial ops use electric.
Here's a house blew up in TX yesterday, after a vehicle plowed into it. Don't know if it's related, but it's odd.
