· A rotary drill rig is one of two main types of drills used for mining. The other type is a percussion or hammer drill. For a rotary drill rig, the drill bit turns under pressure to cut into the rock. As the bit turns, the rock grinds down while compressed air sends it back up the drill to the top to keep the hole and bit clean.
