摘　　要：应用程序升温实验测得氧化动力学参数,分析党家河矿煤自燃临界温度及自燃倾向性,结果表明:测试煤层的煤自燃临界温度为78.96℃,干裂温度为109.99℃;根据公式计算确定了测试煤样煤层属于Ⅱ类自燃煤层,并根据C_2H_4气体出现时对应的温度验证了煤自燃临界温度的可靠性。The parameters of oxidation Kinetics were measured in the heating experiment of the application program,and the critical temperature of coal spontaneous combustion and the tendency of spontaneous combustion were analyzed.The results showed that the critical temperature of coal spontaneous combustion in the coal seam was 78.96℃and the dry cracking temperature was 109.99℃.Based on the formula calculation,it is determined that the test coal seam belongs to the Class Ⅱ self-combustion coal seam,and the reliability of the critical coal spontaneous combustion temperature is verified according to the corresponding temperature of the C2H4gas.
