Abstract：The division of coal spontaneous combustion “three zones” in the gob of a working face is usually based on its distribution in the plane. But for the extra-thick coal seam and the group of contiguous coal seams, the coal spontaneous combustion “three zones” is not only distributed in the plane, but also in the vertical direction. Based on the site measured data, statistics and analysis, the 3D distribution rule of spontaneous combustion“three zones” in 3103 working face in Chenjiagou Mine was obtained, which improved the prediction accuracy of coal seam spontaneous combustion and is of great significance for the mine fire prevention and control and the selection of applicable mine fire prevention technology.
