Through the low temperature o idization analysis and infrared spectrum analysis on coal samp les from the w ork ing surface 1302 in Tangkou Coalm ine, the spontaneous combustion tendentiousness and the m icro- structure change rule of coal samples in o idation process w ere gained, wh ich provides scientific basis for the pre- vention and control ofm ine fires. Key words: low-temperature o idization; spontaneous combustion; m ine fire; infrared spectrum analysis; m icro-molecules structure
