摘　　要：为研究石港煤矿14#,15#煤层煤自燃进程的标志气体,在实验室开展煤氧化升温气体产物的测定实验,主要检测了煤样在氧化升温条件下各种气体组分的发生浓度,对产生气体量随温度的变化曲线进行了深入细致的研究。根据各种气体组分的发生量及最低检测温度,确定了石港煤矿14#,15#煤层的煤自燃预测预报标志气体和煤自燃标志气体生成量的拟合曲线,为该矿煤自燃火灾的预测预报提供了实验依据。In order to investigate the indicator gases in No.14 and No.15 coal seams,the experiment of coal oxidation was conducted.The concentration of the gases produced in the heating-oxidation process were detected and the curve of gas level changed with coal temperature were studied.According to the gas production and the lowest detecting temperature,the indicator gas and its fitting curve between coal temperature and production volume were confirmed,which will provide a basis for the prediction of coal spontaneous combustion.
