Notes: "Recoverable Reserves at Producing Mines" includes no reserves at mines that produced less than 10,000 tons in the calendar year. These small mines are not required to provide reserves data. 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.
* = Data round to zero. W = Withheld to avoid disclosure of individual company data.
