摘　　要：为确定准东矿区煤层自燃的特性,采用色谱吸氧法和氧化动力学方法对比测试准东二矿不粘煤样的自燃倾向性。理论计算煤样的自然发火期。利用傅立叶红外光谱仪对煤样进行漫反射测试,定量分析煤中各官能团的分布特征,建立准东二矿主采煤层的红外简化结构模型。研究结果表明:准东二矿煤属于易自燃煤种,其最短自然发火期为37.6天;煤中有大量的脂肪烃侧链和含氧官能团等活性基团,它们是造成该矿煤样容易自燃的最根本原因。最终建立准东二矿煤样的量子化学结构模型。The spontaneous combustion tendency of Zhundong Ⅱ coal example has been tested by oxidation kinetics, chromatographic and oxygen adsorption testing methods. The spontaneous combustion period of the example has been calculated. With a fourier infrared spectrometer, diffuse reflection testing of the example was done. Distribution of functional groups in the coal molecule was studied. Base on the research, an infrared simplified molecular model of the molecule has been constructed. Results of research show that Zhundong Ⅱcoal is easy self-ignition coal, its spontaneous combustion period is 37.6 d, and that the cause of Zhundong Ⅱ coal＇s easy self-ignition is the reactive groups in the molecule.
