摘　　要：首先建立采空区气体渗流数学模型与物理模型,利用Fluent软件模拟采空区漏风风速分布状况和氧气浓度分布状况,然后利用现场实测数据来验证Fluent数值模拟结果的误差是否在可接受范围内。最后运用MIN-MAX综合处理法将模拟结果和实测结果结合,分析得出综采工作面采空区自燃"三带"的分布规律。The mathematical model and physical model of gas seepage in goaf are established. Fluent software is used to simulate the distribution of air leakage and the distribution of oxygen concentration in goal, then the Fluent numerical simulation results are verified by field data whether it is within acceptable limits. Finally, MIN-MAX comprehensive treatment method is used to analyze the distribution of spontaneous combustion ＂three zones＂ in goaf of fully mechanized coal mining face by combining the simulation results with the measured results.
