1/ For a definition of coal-producing regions, see Appendix C. w/ Withheld to avoid disclosure of individual company data. Notes: Recoverable reserves represent the quantity of coal that can be recovered (i.e., mined) from existing coal reserves at reporting mines. Average recovery percentage represents the percentage of coal that can be recovered from coal reserves at reporting mines, weighted for all mines in the reported geographic area. Excludes silt, culm, refuse bank, slurry dam, and dredge operations except for Pennsylvania anthracite. Excludes mines producing less than 10,000 short tons, which are not required to provide data. Totals may not equal sum of components due to independent rounding. See Glossary for listing of other unions.
