Deep-sea mining IUCN

• Deep-sea mining is the process of retrieving mineral deposits from the deep sea – the area of the ocean below 200 m. • Depleting terrestrial deposits and rising demand for metals are stimulating interest in the deep sea, with commercial mining imminent. • The scraping of the sea floor and pollution from mining processes can wipe out entire species – many yet to be discovered.

Underground mining (hard rock) - Wikipedia

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 ...

Paper: Deep hard rock mining and rock mechanics challenges

Abstract: Mining at depth is associated with high stress magnitudes and often serious ground control problems. Two different extreme conditions: (a) hard rock and seismic problems, and (b) altered weak ore or weak ore contact zones in a hard host rock mass resulting in large deformations and squeezing conditions, are typical for deep mining in Sweden.

Problems in the mining industry in South africa - ECDPM

The current turbulence in the mining industry in South Africa has its roots in several different factors. First, the fall in global demand for platinum and other minerals due to recession; second, the consequences of the Marikana disaster in destabilising labour relations; and third, the structural character of our mining industry. A great deal has been written about the first two factors, so ...
