  • 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 provided.. The earliest forms of stoping were conducted with hand tools or by fire-setting;
