Abstract：The 15101 work face of Jiarui Mine is close distance coal seams mining , and the goaf is loose mix-ture of coal and rock.Through programmed temperature experiments of 14#and 15#coal samples , the relation-ship between different gas generation rate of coal spontaneous combustion and temperature were analyzed .The results show that the generation law of CO , C2 H4 and CH4 etc of two coal seams are basically the same , and the generation law of C 2 h6 is distinctively different.The goaf coal spontaneous combustion index gas of Jiarui Mine is determined, and the index is CO, C2 H4 and C2 H2.The research result provides a reliable basis for preventing the coal spontaneous combustion in the goaf , and guarantees the safe and high efficient production of coal mine.
