   (B)   "Mined lands" includes the surface, subsurface and groundwater of an area in which surface mining operations will be, are being or have been conducted, including private ways and roads appurtenant to any such area, land excavations, workings, mining waste and areas in which structures, facilities, equipment, machines, tools or other materials or property which result from, or are used in, surface mining operations are located.

   (C)   "Minerals" means any naturally occurring chemical element or compound, or groups of elements and compounds, formed from inorganic processes and organic substances, including, but not limited to, coal, peat and bituminous rock, but excluding geothermal resources, natural gas and petroleum.

   (F)   "Reclamation" means the process of land treatment that minimizes water degradation, air pollution, damage to aquatic or wildlife habitat, flooding, erosion and other adverse effects from surface mining operations, including adverse surface effects incidental to underground mines, so that mined lands are reclaimed to a usable condition which is readily adaptable for alternate land uses and creates no danger to public health or safety. The process may extend to affected lands surrounding mined lands and may require backfilling, grading, resoiling, revegetation, soil compaction, stabilization or other measures.

   (G)   "Surface mining operations" means all or any part of the process involved in the mining of minerals on mined lands by removing overburden and mining directly from the mineral deposits, open-pit mining of minerals naturally exposed, mining by the auger method, dredging and quarrying or surface work incidental to an underground mine.
