摘　　要：采用GC-4075型煤自燃测定仪、DSC(差热分析)系统和程序升温实验系统,对孟巴矿不同含水煤样的色谱吸氧量拐点温度、DSC"0"值点温度和拐点温度、临界温度,以及φ(CO2)/φ(CO)比值拐点温度进行了分析,确定出水分对各特征温度的影响规律,为孟巴矿主采煤层自然发火的预测预报提供基础数据与理论支持。In this paper,analysis was made on the inflection point temperature of the chromatographic oxygen absorption capacity of different water-bearing coal samples in Mengba Mine,the ＂0＂-value point and inflection point temperature and the critical temperature of DSC（differential thermal analysis） system as well as the ratio inflection point temperature of φ（CO2）/φ（CO） by using GC-4075 coal spontaneous combustion tester,DSC（differential thermal analysis）system and the experimental system of programmed temperature rise,and the influence law of the moisture on the characteristic temperature of coal was determined,which thus provided the basic data and theoretical support for the prediction of spontaneous combustion in the main mining seams in Mengba Mine.
