Abstract: In order to efficiently control spontaneous combustion on E1404 Working Face Goaf of Xiaoqing Mine, this context was according to the two methods of division for the goaf spontaneous combustion and had numerical simulation analysis.The result showed that the Radiating zone was from 0 to 17.5 m,the Oxidation zone was from 17.5 to 140 m and the Choking zone was the greater zone than 140 m.Then arranging three high temperature points(Near the inlet air lane、the middle of working face、Near the return air lane) along the working face tilt direction in the Oxidation zone, using the software of COMSOL Multiphysics to have numerical simulation analysis ,the result was that when high temperature area is closer to the inlet air lane, the overall temperature in the goaf is higher than that in the inlet air line. According to the result of spontaneous combustion dangerous area analysis in the goaf, put forward the two measures to the fire prevention and control: angle plugging up and down the wind and nitrogen injection.
