You can just gram the all interesting data on mining, metals, minerals and precious stones from our site.Coal mining causes a number of damaging effects. When coal surfaces are bare, pyrite also known as fool's gold, comes in contact with irrigate and air and forms sulfuric acid. As water drains from the mine, the acid moves into the waterways, and as long as rain falls on the mine tailings the sulfuric acid manufacture continues, whether the mine is still in service or not. This process is known as acid rock drainage or acid mine drainage. If the coal is strip mined, the entire exposed seam leaches sulfuric acid, leaving the subsoil infertile on the surface and begins to pollute streams by acidifying and killing fish, plants, and water animals which are responsive to drastic pH shifts.
