#0183;#32;Underground mining:Generally underground mining is adopted when the orebody is too deep and its not economically or technically feasible to use an openpit:Deepest hardrock open pits are over 700 m deep (, Palabora in South Africa and Chuquicamata in Chile).It is increasingly common to progress from openpit to underground mining of the same where surface
It is in proofof concept testing in South Africa. Taken together, the safety and productivity gains from a continuous mining process in hard rock are significant: yielding improvements in tunnel advance rates and reduction in operating costs, while removing people from harm. Robotics will make underground mining safer for all

In South Africa, mining for gold typically involves methods like panning, sluicing, dredging, hard rock mining and byproduct mining. The most effective method used is hard rock mining, since reserves are typically encased in deep underground rock.
Hard Rock Mining Process Supplier South Africa. 2 international mining im is a global publication covering mining and minerals processing technology, methods, equipment and principally by the mining industry itself, it helps extractive operations, both surface and underground, keep abreast of the latest innovations and solutions to help them lower costs, increase performance and
There are six steps in development mining: remove previously blasted material (muck out round), scaling (removing any unstable slabs of rock hanging from the roof and sidewalls to protect workers and equipment from damage), installing support or/and reinforcement using shotcrete etceteras, drill face rock, load explosives, and blast explosives.
There is no doubt that mineral and mining companies have remained part of the biggest companies in South Africa. Despite a significant hit on these companies a few years ago which led to the shrinking of many of them, it is interesting seeing them pick up with records of unprecedented growth.
While Europe (as well as other parts of Britain) specialised in surface and underground coal mining softrock mining, the Cornish mining industry toiled to release metals embedded in hard rock, such as lead, copper, zinc, silver, nickel and tin and thus Cornishmen became world leaders in deep level hard rock mining, at least until the early 20th century.

Mining in South Africa was once the main driving force behind the history and development of Africa''s most advanced and richest economy. Largescale and profitable mining started with the discovery of a diamond on the banks of the Orange River in 1867 by Erasmus Jacobs and the subsequent discovery and exploitation of the Kimberley pipes a few years later.
