shaft mining contrast

What is the difference between shaft mining and drilling ...

2020-8-14  answered Aug 18, 2020 by sadbutterfly100. The difference is that shaft mining is done in open, unprotected areas of the earth, while drilling is done in protected areas, with the exception of areas where there is an active aquifer. In shaft mining, the miner is not even aware that he is digging. In drilling, the miner is aware that he is digging.

Some Challenges of Deep Mining - ScienceDirect

2017-8-1  For classical underground mining, that is, where miners extract ore via shafts, tunnels, and various mining methods, the depth to which the mine can be operated economically depends on the market value of the ore extracted. Thus, for a deposit with a gold content of 10 gt −1 and a market price for gold of $40 g −1, the ore is worth $400 t ...

Strip Mining - an overview ScienceDirect Topics

Andrew P. Schissler, in Encyclopedia of Energy, 2004 2.3 Strip Mining. Strip mining is employed in coal reserves where the overburden is removed in rectangular blocks in plan view called pits or strips. The pits are parallel and adjacent to each other. Strip mining is fundamentally different from contour or area mining on how the overburden is displaced, called spoil handling.
