| Abstract: | Through the experiment and analysis of No.9,No.10 and No.11 Coal Seams in the 10101 coal face of Baozigou Coal Industry,it is found that CO can be used as the index gas to predict the spontaneous combustion of coal seam in the range of 38℃~193℃,C2H4 and C3H6 can be used as the index gas to predict the spontaneous combustion of coal seam in the range of 225℃and 275℃,C2H2 can be used as the index gas to predict the spontaneous combustion of coal seam in the range of 320℃~419℃.The critical oxygen concentration of coal seam spontaneous combustion in Baozigou Coal Industry is 7.0%,which can accurately predict coal seam spontaneous combustion. |
