With the mining activity, the risk treatment problems in the high gas areas get the attention of coal mine enterprises. In the paper, based on analyzing the goaf porosity, air leakage field foundation, the fluid dynamics mathematical model of the goaf gas flow velocity and oxygen concentration is established. Through simulation softwares, three belts of goaf spontaneous combustion at 2506 fully mechanized face in Wangzhuang Coal Mine are divided.
