The electric mining drill mines out iron ore, copper ore, uranium ore, stone and coal, and places it in front of the output tile, on a belt or in a machine or chest that covers the output tile.. The machine is 3×3, but mines in a 5×5 area, extending 1 tile away on each side. Mines copper ore, iron ore, coal, or stone at a rate of 0.5/s and uranium ore at a rate of 0.25/s.
A notable development was a hammering-type rock drill for overhead drilling devised by C.H. Shaw, a Denver machinist, before 1890. Cuttings dropped out by gravity. This machine was called a stoper when it was used in Colorado and California mines. A pneumatic feed held the machine in place and fed the steel into the rock.
