On the basis of physical oxygen uptake, use the instrument to identify the spontaneous combustion of Yang quan coal, and combination the insulation oxide of coal as well as the TG-DSC experiment to analysis of low-temperature oxidation of coal, though the DSC curves, combined with the insulation oxide experimental to analysis the size of the heat. In the end, we can come to the conclusion about the law and the different temperature parameters of the low-temperature oxidation. At the same time, the temperature when a large number of heat released by coals oxidation were also known ,and laid a theoretical foundation to develop prevention and control measures for the spontaneous combustion of coal mines.
