摘　　要：利用加速量热法研究煤炭自燃特性,所用煤样量少、实验时间短.可得到煤炭的初始自加热温度、煤炭升温曲线和耗氧曲线.进行了煤炭自燃过程的化学动力学研究,建立了煤氧化反应的活化能计算方法.得到了试验煤样在缓慢氧化阶段和激烈氧化阶段的活化能数据.The spontaneous combustion characteristics of coal were researched by accelerating rate calorimetry (ARC). This method contains several features, such as small coal samples and short experimental time. The initial spontaneous combustion temperatures, the curves of coal temperature and oxygen concentration versus time were obtained. The spontaneous combustion course of coal sample was analyzed according to the theory of chemical kinetics. The calculation method of activation energy in the oxidizing reaction of coal sample was set up. The activation energy in the slow and fast reaction phases was obtained, respectively.
