Some Challenges of Deep Mining - ScienceDirect

01/08/2017  Working conditions become increasingly hostile as depth increases. In the Witwatersrand gold mines of South Africa, special acclimatization programs were introduced in the mid-1960s, when the mines were around 2 km deep, to prepare miners for work underground . The mines of the Kolar Gold Fields (KGF) in India experienced similar conditions .

What Are the Benefits of Mining? – Research Summary

Most of the hard substances we extract from mines, such as metal ores and crystals (like diamonds) are formed deep within the Earth and pushed upward by rising magma. Coal and similar organic substances were not formed deep within the Earth but rather by the Earth’s surface over millions of years as plants and animals died and left their remains in the slowly acquired sedimentary layers.
