RI 3468 Chemical Considerations Relating To Fires In Anthracite Refuse ? Introduction (1067f50f-d311-4814-b182-e930b23927c4)

Fires in anthracite refuse banks are troublesome and may become exceedingly costly to combat. Instances are known in which refuse-bank fires have grown to such magnitude that entire mining properties have been endangered. In one instance4/ a refuse-bank fire cost the mine management several hundred thousand dollars to extinguish. The exact number of fires formerly existing or now active in the anthracite region of Pennsylvania is not known, There are hundreds of anthracite refuse banks in this region, some very high and large in area, that have never caught fire, although a few are over 50 years old. This would indicate that spontaneous ignition of the material in these banks is improbable, a conclusion confirmed by recent laboratory research.
