| 摘 要： | 以３种不同变质程度煤样的自然发火实验为基础，通过对表征煤自燃特性参数的测算，分析了它们与煤自燃倾向性的关系，并提出用临界温度、煤耗氧速度、ＣＯ产生率和氧转化为ＣＯ的百分率作为鉴定煤自燃倾向性的指标，是有一定参考价值的。

| Abstract: | On the spontaneous combustion experiment of three kinds of coal sample with different metamorphic degree, by means of measuring and calculating some characters, the relation between self combustion tendency and those characters is analysed and it is pointed out that the critical temperature,velocity of oxygen consumption, production rate of carbon monoxide and reaction percentage of oxygen to carbon monoxide may be used as index to appraise the self combustion tendency of coal and this is of certain reference value. |
