摘　　要：采用埋管技术对皖北煤电五沟煤矿CT101工作面采空区进行观测,获取了不同位置测点不同埋深时的温度、氧浓度等数据,通过对各测点温度及氧浓度的变化规律分析,确定了CT101工作面采空区自燃"三带"范围。同时对采空区温度场进行模拟,得出了该条件下采空区"三带"分布的一般规律,并对此种条件下"三带"分布的特殊情况及形成原因做出分析。Pipe - laying technology was applied to observe the goaf of Wugou coal mine CT101 working face, obtaining the data of temperature and oxygen concentration at different position with different pipe laying depth. And through the studying the changing rule of temperature and oxygen concentration of each measuring point, the range of spontaneous combustion ＂three zone＂ in CT101 goaf was determined. And numerical simulation was applied, to simulate the temperature field in goaf, obtaining the general law of ＂three zone＂ distribution in goal, under this condition, exceptional cases of ＂three zone＂ distribution and the forming causes were analyzed.
