challenges of working in 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 .

1. ENVIRONMENTAL IMPACTS OF GOLD MINING IN

Gold mining in Penhalonga represents all methods of gold extraction from deep underground mining, to small-scale mining with mines only a few metres deep, through large-scale alluvial mining and the most infamous gold panning. The area therefore is affected by the environmental impacts of each of these mining methods.

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.

The management of heat flow in deep mines - Wagner - 2013 ...

Sources of heat linked to mining operations are discussed. It is shown that in deep‐level mines, heat transfer from the rock mass accounts more than 75 % of total mine heat load. In highly mechanized coal mines, heat from the use of mining machinery is also significant. Some models of heat flow prediction for deep gold mines are presented.

The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.
