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.
The sublevel stoping mining method is commonly used in large-scale mining. It is a versatile and productive method that is primarily used for large ore bodies with a steep dip, regular shape and defined ore boundaries. Learn more below.

Cobalt occurs as carrollite and cobaltiferous pyrite in approximately equal proportions. The mine produces copper and cobalt from three sources: Mindola Shaft, Central Shaft and South Orebody Shaft. Vertical crater retreat is the predominant mining method while sublevel open-stopping and sublevel caving methods are also used.

Shrinkage stoping is rather hard to mechanize; in addition, an important period may elapse amid the commencements of mining in the stope and the last withdrawal of all the broken ore. The solitary principal basis of tantalum mineral concentrates is the manufacture by Sons of Gwalia Ltd. from its Greenbushes and Wodgina mines in Western Australia.
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 large-scale 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 ...

The deepest mines in the world are the TauTona (Western Deep Levels) and Savuka gold mines in the Witwatersrand region of South Africa, which are currently working at depths exceeding 3,900 m (12,800 ft). There are plans to extend Mponeng mine, a sister mine to TauTona, down to 4,500 m (14,800 ft) in the coming years. [citation needed]

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 .
surface by a dipping 50 metres thick gabbro sill. Sub-level caving, sub-level open stoping, the Janelid method (analogous to an inclined cave) and block caving were all considered as mining methods. Sub-level open stoping was introduced in a trial mining block but, after failure of the method due to premature caving ofthe sill,
