Sublevel Caving is one of the most advanced mining methods. This method is usually undertaken when mining the orebody through an open pit is no longer economically viable. In Sublevel Caving, mining starts at the top of the orebody and develops downwards. Ore is mined from sublevels spaced at regular intervals throughout the deposit.

The Syama Complex, located in the south of Mali, West Africa approximately 30km from the Côte d''Ivoire border and 300km southeast of the capital Bamako, comprises the Syama Underground Mine and the Tabakoroni Open Pit Mine. The Syama Underground Mine is owned by Société des Mines de Syama (SOMISY). Resolute has a 80% interest [.]
stoping in a gold mine in South Africa. Capped safety fuse and igniter cord (burning speed of 18 s/m) make the carrier of the initiating system. The igniter cord is usually fired by an electric starter for igniter cord. Figure 13: Blasting arrangement in breast stoping.

surface by a dipping 50 metres thick gabbro sill. Sublevel caving, sublevel open stoping, the Janelid method (analogous to an inclined cave) and block caving were all considered as mining methods. Sublevel open stoping was introduced in a trial mining block but, after failure of the method due to premature caving ofthe sill,
The ore body is too deep to mine profitably by open pit. The grades or quality of the orebody are high enough to cover costs. Underground mining has a lower ground footprint than open pit mining. The underground mining methods we use include room and pillar, narrow vein stoping and largescale mechanised mining.

Mining 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 ...

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.
Sublevel Open Stoping. Sublevel open stoping requires extensive development in and around the orebody during preproduction. Stope faces and side walls remain unsupported during ore extraction, while support for the country rock is developed as pillars are generated by stoping .
