中文摘要：

煤的低温氧化放热是煤自燃过程的主要热量来源。在水浴保温的实验装置中，对煤样分别进行通入氮气、通入氧气、不通气体时升温（20~80℃）实验，用固定功率的加热棒进行加热升温，模拟煤体高温区域时的氧化。通过对升温曲线的分析和计算，并结合能量守恒方程建立模型，得出煤样的热量产生速率。

英文摘要：

Low temperature oxidation of coal provides the main heat energy for coal spontaneous combustion. The coal samples were put into the water bath device for insulation, and separately forced in nitrogen, oxygen and without air. In each experiment, the sample was heating up （20 80 ℃） by the electrical rod with fixed power to simulate the coal oxidation at low temperature. The temperature histories of coal samples were analyzed and calculated. The model based conservation equation was set up. And the heat energy releasing rate was acquired. Th method and the data are of great significance for understanding the exothermic oxidation of on energy e research coal.
