In the mining process, several resources can be recovered, including coal, metals, limestone, potash, clay and much more. Mining is done with the goal to obtain materials which cannot be obtained at the surface and can also not be created artificially in an economically-senseful way.
Coal mining's effect on the environment reaches beyond the atmosphere — the Earth also feels its effects. Land: Coal mining can lead to soil erosion and dust, and it disturbs large tracts of land.
Many will remember the 2008 TVA Kingston Fossil Plant coal ash spill in which 5.3 million cubic yards of coal ash spilled into the Emory and Clinch Rivers in Tennessee and covered about 300 acres of land, …
As noted in EPA's 2011 report The Effects of Mountaintop Mines and Valley Fills on Aquatic Ecosystems of the Central Appalachian Coalfields, mountaintop mines and valley fills lead directly to five …
Researchers found that the effects of mountaintop coal mining are even more widespread than previously reported: Streams from heavily mined watersheds harbor 40% fewer species than streams with cleaner water.
