Subsurface mines are probably what you envision when you think of mining systems of tunnels and vertical shafts with elevators to take miners underground where they can retrieve the valuable resources Subsurface mines produce large amounts of environmentally hazardous acid mine drainage To keep the underground system of tunnels and mine shafts clear mining companies have to pump out large amounts of water which go into surface ecosystems...
