...-mine fires and 58 refuse piles are currently burning in Pennsylvania ( PDEP 2001b ; Fig. 1 ). Many of the underground fires have not been extinguished because they are elusive or cost prohibitive to stub out. The coal-mining industry in Pennsylvania began in the mid-1700s with the demand for tools...
