  "definition": "1. An opening or excavation in the earth for the purpose of extracting minerals.\n\n2. EPA, in its Clean Water Act effluent limitation guidelines for discharges from mines, has defined a mine as an area of land upon or under which minerals or metal ores are extracted from natural deposits in the earth by any methods, including the total area upon which such activities occur or where such activities disturb the natural land surface. A mine, under this definition, also includes land affected by ancillary operations that disturb the natural land surface, and can include adjacent land whose use is more incidental to mining activities (e. g. , roads, workings, impoundments, dams, ventilation shafts, drainage tunnels, refuse banks, dumps, stockpiles, overburden piles, spoil banks, tailings, holes or depressions, structures, or facilities).\n\n3. Place or area from which commercial minerals are or were removed from the Earth; not including oilfield.\n\n4. Uses of land for extraction of ores, minerals, and rock materials.",
