摘　　要：针对石圪台煤矿低瓦斯矿井3-1煤层存在自然发火潜在威胁,利用程序升温测试系统进行不同温度下(自室温至240℃)的煤样自燃过程气体产生种类和成分实验测定。实验得出:石圪台矿3-1煤应以CO、C_(2)H_(4)作为指标性气体,并辅以C_(3)H_(8)与C_(2)H_(6)来掌握煤炭自燃情况,为煤矿防治自然发火提供参考依据。Aiming at the potential threat of spontaneous combustion in the 3-1 coal seam of the low gas mine in Shigetai Coal Mine,a programmed temperature rise testing system is used to experimentally determine the types and composition of gas generated during the spontaneous combustion process of coal samples at different temperatures(from room temperature to 240℃).The experiment shows that CO and C_(2)H_(4)should be used as indicator gases for the 3-1 coal in Shigetai Mine,and C_(3)H_(8) and C_(2)H_(6) should be supplemented to grasp the situation of coal spontaneous combustion,providing a reference basis for the prevention and control of spontaneous combustion in coal mines.
