Extracting ores | Mining of mineral resources | Siyavula
Shaft mining. Often the minerals are not found close to the surface of the Earth, but deeper down. In these cases underground mining, also called shaft mining, is used. Examples of underground mining in South Africa are mining for diamonds, gold and sometimes the platinum group metals (PGM).
What Are the Benefits of Mining? – Research Summary
Mine shafts may collapse even when constructed according to modern safety regulations. ... Some small mining operations are feasible because the minerals being extracted are rare, highly valued, and easily transported. For example, gold and silver mining are still profitable for individuals who have the resources to process a lot of ore.
Underground Mining Methods and Equipment
widespread, when smallscale operations on veintype deposits prevailed. However, with rising costs, the scarcity of skilled labor and the trend toward mechanization, the method has been largely displaced by sublevel stoping and cutandfill. Sublevel stoping will therefore be the only unsupported methods examined in detail here. Supported methods require substantial amounts of artificial ...
