Abstract In order to develop scientific and reasonable coal seam spontaneous combustion comprehensive preventive measures, reduce spontaneous combustion accidents during production, F6103 Buliangou Mine working face coal seam spontaneous combustion ‘ three zones ’ observation and analysis was done, based on FLUENT numerical simulation calculation and the method of using MIN - MAX, analog study was conducted. The result showed that F6103 oxidized spontaneous combustion during mining periodic belt width was 51.00 m, the minimum safety velocity was 3.40 m/d, which provided the basis for the establishment of coal seam spontaneous combustion prevention measures.
