1/ Mines that produce greater than 50 percent of coal by continuous mining method. 2/ Mines that produce greater than 50 percent of coal by conventional mining method. 3/ Mines that have any production from longwall mining method. A typical longwall mining operation uses 80 percent longwall mining and 20 percent continuous mining. 4/ Mines that produce coal using shortwall, scoop loading, hand loading, or other mining methods or a 50/50 percent continuous/conventional split in mining method, or mines that produce less than 10,000 short tons, which are not required to provide data. 5/ For a definition of coal-producing regions, see Appendix C. * Data round to zero. Note: Totals may not equal sum of components due to independent rounding.
