hammerpick
A compressed-air-operated hand machine used by miners to break up the harder rocks in a mine. It consists mainly of a pick and a hammer operated by compressed air. The hammer driving the pick is set in a cylinder, where the compressed air enters and presses the hammer, which in turn drives the wedge-shaped edge of the pick into the rock in short sufficient shocks of from 1,500 to 2,000 blows per minute.
