    Note:
  • Tables are a result of VCCER analysis. Totals may differ slightly from those listed elsewhere in this web site due to different data parameters and methods of obtaining information. Total average productivity is extrapolated by dividing total short tons produced by total hours at all mines producing coal.
  • "0" (Zero) production category represents licensed mines that produced no coal for the year.
  • Totals may not equal sum of components because of internal rounding.
