Relative Self-Heating Tendencies of Coal, Carbonaceous Shales, and Coal Refuse

摘要

Studies on the initiation and propagation of mine fires have dealt almostexclusively with coal. It has been assumed that the self-heating potential of carbonaceous shales and coal wastes is relatively low. However, in abandoned coal mines and waste banks, initiation and propagation of fires may be strongly dependent on the self-heating tendency of these materials. The purpose of the study was to compare the self-heating probability of carbonaceous shales and coal wastes to that of coals.
