煤层自然发火的指标气体是矿井煤体氧化生热,出现温度变化时可以稳定探测的气体.使用指标气体可以早期探测到煤层自然发火的发生,减少不必要的经济损失.开展了煤层自然发火指标气体试验研究,测定了煤样的气体CO,CO2,CH4以及C3H8等在不同热解温度下的浓度.根据煤样不同气体浓度的变化,选出更能够预测自然发火的气体作为煤层的指标气体,希望能为矿区的火灾预防起到指导作用.

　　The indicator gas for spontaneous combustion of coal seams is the gas generated by the oxidation of coal in mines, which can be stably detected when temperature changes occur The use of indicator gases can detect the occurrence of coal seam spontaneous combustion early and reduce unnecessary economic losses We conducted experimental research on natural combustion index gases in coal seams and measured the concentrations of gases such as CO, CO2, CH4, and C3H8 in coal samples at different pyrolysis temperatures Based on the changes in gas concentrations in coal samples, select the gas that can better predict spontaneous combustion as the indicator gas for coal seams, hoping to provide guidance for fire prevention in mining areas

　　Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used a portable methane conversion furnace to detect the content of trace amounts of carbon monoxide and carbon dioxide in coal seam spontaneous combustion marker gases. The area external standard method was used for quantification, and the results were satisfactory.
