by R.S. Sites and K.K. Hostettler, 51 pages, 33 figures, 22 tables, 1991. Available coal resources for the Appalachia quadrangle in Wise and Lee counties, Virginia were calculated using additional factors not used in traditional coal resource studies. Land-use restrictions include oil and gas wells, cemeteries, streams, towns, highways, pipelines, powerlines and national forests. Technical restrictions to mining include oil and gas wells, buffers around existing mines and interburden thicknesses of less than 40 feet. As of 1990, 26 percent of the coal had been mined. Of the remaining coal, 70 percent is available for mining after applying the land-use and technical restrictions.
