Individual coal bed statistics are depicted in the twelve tables of the Appendix .
Much more detail is presented in the individual reports cited for each of the study areas.
Figures 3 and 4 show the same information by percentages. A total of one billion tons of coal is estimated to be unavailable due to landuse and technologic restrictions in the four areas studied. Of the original resources in the four areas, only 61 percent are estimated to be available for mining under current conditions. The range in the amounts of available resources is surprisingly small - 58 percent in the Vansant quadrangle to 64 percent in the Sylvester quadrangle. Technologic restrictions range from a minimum of 11 percent in the Noble quadrangle to 28 percent in the Sylvester quadrangle, a 25 percent average.
