How Does Coal Mining Affect the Environment?
Apr 05, 2020 · Coal mining takes place in two ways: surface mining and underground mining. Both pose threats to the environment, but in different ways. Surface mining takes place primarily on mountaintops. Setting up mining operations requires clear-cutting, often of vast tracts of forests and vegetation. This removal disturbs habitats and alters landscapes.

After mining finishes, the mine area must undergo rehabilitation. Waste dumps are contoured to flatten them out, to further stabilise them. If the ore contains sulfides it is usually covered with a layer of clay to prevent access of rain and oxygen from the air, which can oxidise the sulfides to produce sulfuric acid, a phenomenon known as acid mine drainage.
