| 摘 要： | 为了掌握煤炭自燃的微观机理，通过实验手段对几个矿区的原始煤样和氧化煤样进行了红外光谱分析，分析表明：在煤炭低温氧化过程中，芳烃和含氧官能团的含量随着温度的升高而增加，而脂肪烃的变化则不明显．因此，可以通过煤炭中芳烃和含氧官能团的含量来判断煤炭自然氧化的程度，为防止自然发火作出早期预报．

| Abstract: | In order to understand the microcosmic mechanism of coal spontaneous ignition, the authors made a series of infrared spectral analysis of fresh and oxidized coal samples collected from three different coal mines. The experiment result showed that during the process of low temperature oxidation, the content of aromatic hydrocarbon and oxidized functional group is getting more and more along with the uprising of temperature, while the content of aliphatic hydrocarbon changed randomly. This characteristic can be used to judge the degree of spontaneous ignition of coal and give prediction of spontaneous fire as soon as possible. |
