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。
In order to determine the characteristics of coal spontaneous combustion in Zhudong coal mine, the spontaneous combustion tendency of non-stick coal samples in quasi-Dong 2 mines was compared with the method of chromatographic oxygen absorption and oxidation kinetics. Theoretical calculation of coal samples of natural fire period. The samples were diffusely reflected by Fourier transform infrared spectroscopy to quantitatively analyze the distribution of each functional group in coal and establish the infrared simplified structure model of the main quarry in Zhudong II Mine. The results show that the quasi-Dong 2 coal is spontaneous coal with the shortest spontaneous combustion period of 37.6 days. The coal contains a large number of active groups such as aliphatic hydrocarbon side chains and oxygen-containing functional groups, Easiest spontaneous combustion of the most fundamental reason. Finally, the quasi-East two coal samples of the quantum chemical structure model.
