• Description:
  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 design. Adequate geologic and hydrologic data are necessary to avoid areas where high inflows may occur, or to plan for handling and treating the inflows. This report discusses several methods to reduce or prevent inflows, including surface and stream diversions, dewatering of aquifers, grouting and sealing, and leaving barrier pillars between adjacent mines. Mine closure and down-dip mining are also considered in reducing acid mine drainage formation. The design of water-handling systems in a mine is covered in detail. The system must be integrated throughout a mine. Methods of determining pump requirements and size, pipe sizing, and various types of acid mine drainage treatment are discussed.
