Stoping, in mining engineering, the opening of large underground rooms, or stopes, by the excavation of ore.Stoping is practiced in underground mineral mining when the surrounding rock is strong enough to permit the drilling, blasting, and removal of ore without caving.In mines where the rock requires no artificial support, the operation is known as open stoping.

Sub-level caving also allows for a slightly more selective extraction of the orebody than is attainable through block or panel caving. Production rates achieved in sub-level caving operations are typically lower than for block caves but higher than for stoping methods." CAVING requIremeNts Caving is a non-selective, bulk mining method.
Table of ContentsStopingStope-Development MethodsRaisst of Driving Raises Stoping The foregoing discussion relates to general mine development and covers the work required to reach and penetrate the ore bodies and to provide the main arteries through which the ore is taken from the mine. These arteries provide mine drainage and avenues for travel and transportation of .
A mining method involving overhand, underhand, and shrinkage stoping. Its characteristic feature is the use of sublevels. The sublevels are worked simultaneously, the lowest on a given block being farthest advanced and the subs above following one another at short intervals. The uppermost sublevel underneath the cover is partly caved.

Sub-Level Caving Subsidence reaches surface at the Ridgeway underground mine. Using this method, mining is planned to extract rock from the stopes without filling the voids; this allows the wall rocks to cave in to the extracted stope after all the ore has been removed. The stope is then sealed to .
a limited opening which creates challenges for the mining method. In SLC operations the decision to stop loading from a draw point and proceed to the next one is a critical decision. If a draw point is closed early, ore is lost in the draw point and cannot be conclusively recovered at the lower levels. If it is closed
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. The ore body should be fairly regular in shape and well-defined.
