Underground mining: Complicated problems, simple

2012-11-29  Every underground mine faces the same problem with dust in its tunnels and development panels, and currently most deal with the issue in the same way – using an auxiliary fan to disperse the stone dust. This is crucial as not only does the dust make operations difficult, it also poses an inhalation risk to the workers.

Some Challenges of Deep Mining - ScienceDirect

2017-8-1  Although some surface mines now operate at depths in excess of 1 km, slope stability and other issues dictate a change to underground mining if the orebody continues in depth. 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

Causes, Effects Solutions for Ocean Mining - EC

Even if deep-sea mining is often quite costly since big machines have to be operated on the ground of the ocean, many companies think it will still be worth it to do so due to the scarcity of resources from conventional mining activities which may lead to a significant increase in world market prices for scarce metals and therefore to an increased profit for companies who specialized in ocean mining.
