challenges of working in a deep gold mine

Some Challenges of Deep Mining - ScienceDirect

Aug 01, 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 .

Deep Mining: A Rock Engineering Challenge SpringerLink

Apr 13, 2019  To illustrate these points, the effects of depth on mining conditions in “deep” coal and gold mines are compared. At a depth of 1000 m below surface, the vertical in situ rock stresses are very similar in the two mining situations, namely about 25 MPa in the case of the coal mines and 27 MPa in the case of the gold mines.

Environmental Risks of Mining

Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.
