The authors describe a series of laboratory experiments designed to investigate the influence of moisture on the spontaneous heating of coal on a quantitative basis. The experiments have shown next two conclusions.The spontaneous ignition point is found to be lowest when the moisture content is zero, and it progressively increases with the increase of the moisture content of coal.The relation between the moisture and the rate of temperature rise is expressed by the phrase that the more, the lower. The highest rate of temperature rise is shown by dry coal.
