Mine Plan
Some of the largest overseas coal producers, notably China and India, are investing heavily in coalfired electric power plants and large ultramodern coal mines. These investments, in response to severe energy shortages, suggest increased coal production in these countries for the next few decades at least. The third major mining component, the production of metals, tends to be far more ...
Outline of mining
Surface mining, mining conducted down into the ground, but with the sky open above Openpit mining, where the overburden is removed and put in a different loion, leaving a large pit at the end. Strip mining, where the overburden is stripped off and placed onto the area where the mineral (usually coal) has already been mined out, allowing the surface to be returned to roughly how it was before
