Underground Mining, Underground Mining

TechnologyAdvantagesTypesSummaryUnderground mining is carried out when the rocks, minerals, or precious stones are located at a distance far beneath the ground to be extracted with surface mining. To facilitate the minerals to be taken out of the mine, the miners construct underground rooms to in. The mining company selects the best feasible way to get the minerals extracted out.

About coal mining impacts Greenpeace International

About 40 percent of the world’s coal mines are the more damaging strip mines (also called open cast, open pit, mountaintop or surface mining). Strip mining impacts. Strip mining is highly destructive. Yet the industry often prefers to strip mine because it takes less our and yields more coal than underground mining.
