Stoping Wikipedia

Stoping is the process of extracting the desired ore or other mineral from an underground mine leaving behind an open space known as a stope Stoping is used when the country rock is sufficiently strong not to collapse into the stope although in most cases artificial support is also The earliest forms of stoping were conducted with hand tools or by fire setting later gunpowder
