| 摘 要： | 煤炭自燃是一个复杂的物理化学过程，煤的水分是影响氧化进程的重要因素。论述了水分在煤炭自燃初始阶段的催化作用和对煤炭自燃的抑制作用，研究了水分在煤炭自燃过程的物理化学机理，针对一些矿区煤炭自燃的实例对其水分的影响进行了分析．煤炭中水分对煤的氧化、蓄热和散热过程都有一定的影响，煤中水分对煤炭自燃到底是起阻化抑制作用，还是起催化触媒作用，应根据具体条件而论。

| Abstract: | Spontaneous combustion of coal is an extremely complicated physical chemistry process and the moisture is the important factor of the influence of coal oxidation. The effects of moisture on spontaneous combustion of coal was discussed from the catalyzing function in the initiation stage of spontaneous combustion and the suppressing action to the coal respectively in this paper. Then, the physical chemistry mechanism of spontaneous combustion was studied. Finally, in allusion to the examples of some diggings, the account of spontaneous combustion by the influence of moisture was analyzed. Moisture in coal has effect on coal oxidation, heat storage and heat emission process, but moisture in coal is an inhibitor or a catalyzer in spontaneous combustion should be analyzed according to the specific condition. |
