摘要：

One of the challenges in the coal mining industry is self-heating of coal as this can become a problem during mining operations, stockpiling and transportation. This study reviews the mechanism of self-heating, areas of spontaneous combustion, various factors influencing self-heating and different experimental studies to predict its occurrence. The technical control measures applied to minimise self-heating with special consideration to South African coals are also discussed. The distribution and association of unknown materials accelerating spontaneous combustion at different bands within the seam is yet to be studied. A site evaluation of the effects of these parameters is underway.
