煤層自然發火的指標氣體是礦井煤體氧化生熱,出現溫度變化時可以穩定探測的氣體.使用指標氣體可以早期探測到煤層自然發火的發生,減少不必要的經濟損失.開展了煤層自然發火指標氣體試驗研究,測定了煤樣的氣體CO,CO2,CH4以及C3H8等在不同熱解溫度下的濃度.根據煤樣不同氣體濃度的變化,選出更能夠預測自然發火的氣體作為煤層的指標氣體,希望能為礦區的火災預防起到指導作用.

　　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.
