heading-and-stope mining
A stoping method used in thicker ore where it is customary first to take out a slice or heading 7 to 8 ft (2.1 to 2.4 m) high directly under the top of the ore and then to bench or stope down the ore between the bottom of the heading and the bottom of the ore or floor of the level. The heading is kept a short distance in advance of the bench or stope.
