摘　　要：通过对影响煤炭自燃因素的分析,建立了采空区内遗煤自燃过程数学模型,可随时预测不同漏风强度和不同推进速度条件下,采空区遗煤自然发火的危险性,对丁集煤矿1262(1)首采面采空区遗煤自燃过程中,氧化时间、工作面推进速度对煤温的影响进行了计算机模拟,成功预报了在回采过程中采空区遗煤不自燃,确保了该工作面安全回采。Based on the study of main factors of coal spontaneous combustion, a mathematical model for the process of coal self - heating in mines was put forward. This model can be used to predict the possibility of spontaneous combustion in various factors. The influence on coal temperature of oxidation time, advance speed of working face were simulated in the process of the combustion of left coal in the first goal of coal face 1262（ 1 ） in Dingji Coal Mine in computer, and successfully predicted the incombustion of left coal in goal in the process of actual mining and ensured safety reproduction of coal face 1262（ 1 ）.
