摘　　要：为了解决凌志达煤业15号煤层自然发火能够准确预测的问题,通过对煤加热升温产生气体过程的实验并结合优先选择标志性气体的原则,研究确定了15号煤层自然发火标志性气体温度临界值,为下一步煤矿防灭火治理工作和安全高效生产提供基础数据支撑。In order to solve the Lingzhida No.15 coal seam spontaneous combustion can be accurately forecast problems,through the experiment of gas on coal heating heating process and the principle of priority landmark gas research identified the No·15 coal seam spontaneous combustion gas temperature threshold and iconic work for the next step of coal mine fire prevention management and provide basic data to support the safe and efficient production.
