Mine Water Pollution: The mining Industry has to discharge millions of gallons of water every day to the adjacent water courses thereby may cause water pollution problems in and around the mining areas. Mine water discharge also forms the main source of various water supplies particularly potable in the thickly populated coal fields.

Chemical, Air Dust Pollution: Underground mining allows coal companies to dig for coal deeper into the ground. The problem is that huge amounts of earth and rock are brought up from the bowels of the earth. These mining wastes can become toxic when they are exposed to air and water. Examples of toxins are mercury, arsenic, fluorine and selenium.

Subsurface mining frequently goes below the water table so water must be constantly pumped from the mine. Acid mine drainage results from the outflow of water from metal mines, coal mines, or other areas in which the ground has been disturbed. Metal salts, such as Fe +2, are oxidized upon contact with air to more highly acidic aquo species.
