The treatment of acid mine drainage can amount to a considerable expense over the life of a mine where highly pyritic materials are present. Two possible options to reduce costs are reducing inflow to a mine or collecting and transporting the water once it has entered a mine to minimize its contact with acid-producing material. Planning the water-handling system should be part of the initial mine
