1/ For a definition of coal-producing regions, see Appendix C. 2/ Includes mines with production of less than 10,000 short tons, which are not required to provide data. w/ Withheld to avoid disclosure of individual company data. NA/ Not available. Notes: Productive capacity is the maximum amount of coal that can be produced annually as reported by mining companies on Form EIA-7A. Capacity utilization is the ratio of total production to annual productive capacity as reported by mining companies on Form EIA-7A. Coal production excludes silt, culm, refuse bank, slurry dam, and dredge operations except for Pennsylvania anthracite. Totals may not equal sum of components due to independent rounding.
