摘　　要：利用傅立叶红外色谱(FTIR)分析了黄陵建新煤矿4#煤层煤样在不同温度下的氧化物中各官能团的组成及变化,并对煤分子中活性基团氧化途径进行分析,揭示了煤中活性基团随氧化温度变化的规律,掌握煤自燃过程中活性基团活泼性和自燃的关系,为煤自燃的有效预防提供了理论支持。Using Fourier transform infrared spectroscopy （FFIR）, the paper analyzed the composition and variation rules of functional groups in oxides of coal samples under different temperatures, researched the oxidation pathway of active groups in coal molecular, re- vealed the variation rules of active groups with oxidation temperature and mastered the relationship between the activity of active groups and coal spontaneous combustion. The research provides theoretical support for effective prevention of coal spontaneous combustion.
