Underground Coal Mines Dewatering Systems

Underground mines contri- bute a large portion of the acid drainage water which constitutes a widespread pollution problem throughout the eastern coal mining regions. In underground mines AMD is formed when iron disulfides e.g. marcasite pyrite decompose on exposure to air forming a complex series of compounds that are highly soluble in water.
