so -- so you know that's just the way it was. the community worked to support the people. here's the fun part! >> anthony: cool! >> jim keane: how many holes do you usually drill to make a round? >> matt: oh, between twenty and thirty. >> anthony: what is a round? >> matt: this pattern has to be drilled out and every time you advance the face; that is a round. you drill it, you load it, y blast it, you muck it, you bolt it, you drill it again. and that's a cycle. we're in the loading process right here. they call collar priming or top priming this hole. quick, fill away! >> anthony: back in the day it was dynamite. but in the sixties, they started switching over to this stuff; anfo- ammonium nitrate and fuel oil. >> matt: ok so i've got everything charged up and loaded. now we get to time it. >> matt: this is kind of where i got hooked on mining. as soon as i set that first round off it was how do i do another one?
