HE Qi-lin, WANG De-ming (1. School of Mineral and Energy Resource, CUMT, Xuzhou, Jiangsu 221008, China; 2. Department of Resources Development and Management Engineering, Anhui University of Science and Technology, Huainan, Anhui 232001, China)  
Based on the study of main factors of coal spontaneous combustion, a mathematical model for the process of coal self-heating in mine was put forward. This model can be used to predict the possibility of spontaneous combustion in variety factors. The influence of oxidation time, advance speed of working face,thinckness of lose coal on coal temperature was simulated in the process of the combustion of lose coal in the goaf of coal face 7 235 in Xuzhuang Coal Mine by computer. The situation that the lose coal in goaf in the mining process did not combust and it maybe combust in the process of removing support frame was predicted. The predicted result is in accord with actual state.
