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; later gunpowder ...

Considerations for Sublevel Open Stoping - onemine.org

Sublevel stoping generally is a large-scale open stoping method. It sometimes is referred to as long-hole or blasthole stoping. This method usually is applied to strong ore bodies that require minimal support and are surrounded by strong country rock.

Mining Stope Development Method

Sublevel stoping, sublevel caving, top-slicing, and block-caving require more stope preparation before ore extraction can begin. In sublevel stoping (a form of open stoping), ore chutes, manway, and “starting raises” must be put up and one or more drifts driven on each sublevel (fig. 60, B).

Definition of sublevel stoping - mindat.org glossary

Definition of sublevel stoping. i. In this mining method, the ore is excavated in open stopes, retreating from one end of the stope toward the other. The orebody is developed first by a series of sublevel drifts above the main haulage level. The sublevels are connected by a starting raise at one end of the stope and by a passageway raise for ...

Mining - Underground mining | Britannica.com

Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the surface.
