摘要
根据采空区顶板的冒落压实状况，通过采空区流场的计算机模拟分析，得出了采空区内自燃“三带”的分布状态．通过对采空区内遗煤温度和气样成分的观察分析，验证了计算机模拟分析的结果．结合采空区遗留浮煤的分布状态，充分阐明了“两道两线”（进风道、回风道、切眼线和停采线）是采空区内发火最危险部位，也是采取防灭火措施的重点部位．
On the basis of falling and compacting status of the roof, the distribution regularities of spontaneous combustion “three zone” were obtained by computer simulation of the flow field in goaf. The result was tested and verified by measuring and analyzing the temperature of residual coal and the component of gas sample in goaf. In consideration of the distribution status of the residual coal, it has been fully explained that the “two roadways and two lines” , intake airway, return air way, mining starting line, and terminal line, are the most dangerous area where the spontaneous combustion of coal may take place. So it is the most important area where preventing and extinguishing measures should be taken.
