结合义马煤业集团耿村煤矿工作面立体瓦斯抽采的实际情况,通过低温氧化试验,参照标志气体优选原则,确定CO,C2H4作为主要标志气体指标,C2H6作为辅助指标,并定量出采空区CO体积分数的临界值,建立了耿村矿23号煤层自燃预测预报标志气体体系.同时为克服采空区气体抽样的困难,推导出高抽巷气体成分与采空区气体成分间的关系,利用高抽巷的气体成分预测采空区浮煤的自然发火.

Combined the practical situation of working face in Gengcun Coal Mine of Yima Coal Industry Group and the optimization principle of sign gas,CO and C2H4 were set as the main sign gas index and C2H6 was set as the auxiliary index,the critical value of volume fraxon of CO in the goaf was quantified through the low tempe-rature oxidation experiment,and the system of sign gas was built up to predict coal spontaneous combustion of Number 23 in Gengcun Coal Mine.Meanwhile,in oder to overcome the difficulty of the gas sampling in the goaf,the relation between the gas component in the goaf and the high drainage roadway gas has been deduced,and the high drainage roadway gas has been implemented to perdict the float coal spontaneous combustion in the goaf.
