Sublevel Caving Safety. Sublevel caving is a relatively safe mining method since the operations take place in small areas at a time and are highly mechanized. The uniformly distributed nature of generally 5mx3.7m sublevel nature of drifts aids in the safety of this mining method.
Sublevel Caving . Sublevel Caving is one of many different methods for underground hard rock mining. It is a large-scale mining method suitable for large ore bodies with a steep dip and a rock mass with a host rock in the hanging wall will fracture under controlled conditions.
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.

Transverse Longhole Stoping is a popular large scale underground mining method known for its ability to simplify stope sequencing. It is an open stoping method and is very similar to sub-level open stoping, Longitudinal longhole retreat, and blast hole stoping.
We use this for mining platinum. Large scale mechanised mining methods we use include: long-wall mining, where a long wall of coal is mined in a single slice, usually by a large machine. sub-level-caving, where levels of the ore are blasted by explosives; and

Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies. Soft rock mining refers to excavation of softer minerals such as salt, coal ...
For sublevel stoping the ore body and walls should be strong enough to support open stoping. In this 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 ...

Cut-and-fill stoping is applicable to the mining of firm ore enclosed within walls, one or both of which are weak and heavy. The deposits may be tabular in form, dipping at angles steeper than the angle of repose of the broken ore (or flatter, if scrapers are employed for moving the ore in the ore passes), or to wide, thick ore bodies or masses.
