CABLE-TOOL DRILLING

Domain	Definition
Mining	A method of drilling, now largely replaced by rotary drilling, in which the rock at the bottom of the hole is broken up by a steel bit with a blunt, chisel-shaped cutting edge. The bit is at the bottom of a heavy string of steel tools suspended on a cable that is activated by a walking beam, the bit chipping the rock by regularly repeated blows. The method is adapted to drilling water wells and relatively shallow oil wells. (references)
