Jiangou coal mine is a fully mechanized working face, with a height of 23 meters, serious air leakage in the goaf, easy spontaneous combustion of the coal seam, easy spontaneous combustion of the residual coal in the goaf. In order to prevent and control the spontaneous combustion fire in the goaf, we analyzed the thermal weight of B3 + 6 coal seam, obtains five characteristic temperature points. We conducted the heating and oxidation experiment of coal, analyzes the variation rule of the generated gas and its concentration with the temperature, and obtain the CO concentration distribution map of goaf based on the numerical simulation and on-site monitoring data.
