underground mining production

[GIFS] The 5 Stages of the Mining Life Cycle . Operations . Mining .

Production. The two most common methods of mining are surface and underground mining. The method is determined mainly by the characteristics of the mineral deposit and the limits imposed by safety, technology, environmental and economical concerns. The first step in the production stage is recovering the minerals.

Why underground mines cost higher compared to surface coal .

Geographic landscape. Recall that it takes more time, pressure, and heat to form higher ranked coal. This means higher ranked coal is largely buried deeper in the Earth's crust, while lower ranked coal is closer to the surface. About 70% of total coal production from Appalachia is recovered from underground mines, while.
