With the continuous application of gas drainage in mine gas control, many high gas mines adopted gas drainage as the root cause of gas prevention and control, but coal seam drilling was prone to borehole coal spontaneous combustion, which constituted safe production of mines, with serious security risk. The 2902A working face of Dongpang Mine was taken as an example, the treatment technology and preventive measures of spontaneous combustion of coal in the spontaneous combustion coal seam of high gas mine were introduced, which provided reference for other similar mines.
