摘　　要：对不同温度下的氧化煤样通过红外光谱分析其微观结构及特征,得到煤样在不同低温氧化阶段的基团变化,从微观角度掌握煤样氧化过程的变化规律。通过对唐口煤矿1302工作面煤样的低温氧化和红外光谱分析,得到唐口煤矿煤样在低温氧化阶段的自燃倾向性和氧化过程中微观结构的变化规律,该成果为制定矿井内火灾的防治技术提供了科学依据。Based on the analysis of the micro-structure and characteristics of oxidized coal samples under different temperatures by infrared spectrum analysis,the radical change of coal samples at different low-temperature oxidization stage and the changing rule of coal oxidization process were obtained.Through the low temperature oxidization analysis and infrared spectrum analysis on coal samples from the working surface 1302 in Tangkou Coalmine,the spontaneous combustion tendentiousness and the micro-structure change rule of coal samples in oxidation process were gained,which provides scientific basis for the prevention and control of mine fires.
