The breast auger was used by early miners to drill holes into the face of the coal. Explosives, attached to a fuse, would then be placed in the hole, followed by a tamping material to seal the opening. The hole would then be "fired" by lighting the fuse, which would be of sufficient length to allow the miner to get to safety. The resulting "shot" would loosen the coal, which in …
