摘　　要：采用氧弹法等方法对2种典型煤(XJ煤和QJY煤)热值进行了测量。采用热重试验法对试验煤样的燃烧放热特性进行了研究。计算并对比分析不同煤样的热释放速率。2种煤对比可知,XJ煤在较低温度水平时即可集中释放大量热,QJY煤在较高的温度水平较为长时间地平均地放出大量热。The calorific values of the two typical coal samples（XJ coal and QJY coal） were measured by oxygen bomb method.The combustion heat release characteristics of these two coal samples were studied by thermogravimetric analysis.Heat release rates of two samples were calculated and compared.XJ coal can release more amounts of heat at low temperature at a relatively short duration, while QJY coal can release heat at a relatively longer duration at high temperature level.
