form of coal mining

Conventional mining is the oldest method and accounts for only about 12% of underground coal output. In conventional mining, the coal seam is cut, drilled, blasted and then loaded into cars. Continuous mining is the most prevalent form of underground mining, accounting for 56% of total underground production. get price

Coal mining exposes sulfides primarily pyrite in coal and associated rocks to oxygen and moisture. These oxidize the sulfides and form sulfuric acid. The resulting acidic waters referred to as acid mine drainage AMD

12 Environmental Effects of Coal Mining

Possibly one of the scariest environmental effects of coal mining is the threat of acid rain. The high acidity of AMD remains in the water supply even through evaporation and condensation, which enables it to stay in the atmosphere and eventually return in the form of "acid rain," thus perpetuating the cycle of pollution.
