摘　　要：利用灰色B型关联分析法对煤低温氧化过程中不同煤种表面官能团随温度的变化关系进行了研究。通过计算B型关联度发现甲基、亚甲基是煤低温氧化的主要贡献基团;煤氧化过程最有可能的是生成C=O、-CHO(芳香酮、醛类羰基)类基团;气煤的关联度区间最大,说明其自燃过程受活性基团影响最严重。We calculated the grey B-mode correlation of active structures in coal surface and the temperature.The results showed that the methyl and methylene groups make major contribution to the spontaneous combustion of coal.The aromatic ketone and aldehyde carbonyl groups were mostly produced during the process of coal oxidation.In addition,the grey correlation range of gas coal was the largest,which revealed that the process of spontaneous combustion of gas coal was mostly affected by active groups.
