摘要：

To investigate the spontaneous combustion of coal, a moderate scale experiment was carried out on the XK-III apparatus. Total 1500 kg coal was stored in the furnace with air supply. The coal undergone 39 days to reach 158 degrees'C, at which the coal started to combustion. The temperature history of coal shows that the temperature rise was sped up after 30 days when the temperature is 60 degrees C. Before that, the coal was undergoing a slow oxidation process, and after that, the heating rate increased from 0.4 degrees C/h to 2.5 degrees C/h and the oxygen consumption increasing correspondingly. Furthermore, the production rate of CO and CO2 increases rapidly. Therefore, the thermal runaway temperature is at 60 degrees C for the 1500 kg coal in a cylinder stockpile.
