本文通过对孟坝煤矿不同含水量煤样的程序升温实验，研究了不同含水量煤样的自燃特性，通过对不同温度条件下的产气率、放热强度和耗氧率的分析，得出不同含水量煤样在程序升温氧化过程中，结果表明，在孟坝煤氧化自燃过程中，水分对煤氧化自燃的影响有一定的规律，确定了临界水分点，为有效防治煤炭自燃提供了基础数据和理论支持。
In this paper,program temperature experiments are carried out to research spontaneous combustion characteristics of coal samples with different contents of moisture of mengba coal mine.Through the analysis of gas production rate under different temperature condition,exothermic strength and oxygen consumption rate,during the program temperature oxidation process of different contents of water,the results show that some rules of the effects of moisture on coal oxidation and spontaneous combustion can be during the oxidation and spontaneous combustion of mengba coal,the critical moisture point is ensured,which provide basic data and theory support for efficient prevention of coal spontaneous combustion.
