Looks like we will be using all of our 10 days to drill and blast. With each hole 3-4′ deep, the guys can get up to 50 holes blasted in a day. The orange sticks of nitro are put down the holes after they are drilled to depth and provide most of the explosive impact. They also need a blasting cap style charge to be embedded in them before they will be functional and this also serves as a safety device to keep the explosives disarmed until needed.
