摘要
根据兖州矿区煤样自然发火实验，测算出煤不同温度时的发热强度和耗氧速度，在此基础上，通过煤自然发火数值模拟计算，分析不同供风强度、散热边界条件和煤的粒度等对煤最短自然发火期的影响关系，从而确定出实际开采条件下煤层的最短自然发火期．
Based on the experiments of Yanzhou coal sample, the velocity of oxygen consumption and exothermic intensity are calculated respectively. Then according to the mathematics model of spontaneous combustion, it is analyzed that the dependence of spontaneous combustion on air quantity, endothermic boundary conditions, and size of coal. Finally, the shortest spontaneous combustion period is concluded.
