摘　　要：采空区漏风是引发煤炭自燃的重要原因。为研究漏风规律,以滕东生建煤矿3下煤层采空区为研究对象,利用GAMBIT软件建立了采空区计算模型,借助流体仿真软件FLUENT对采空区内部空气流动进行动力性分析,模拟了不同时刻条件下采空区内风速分布,得出了流场规律。Air leakage in goaf is an important cause of coal spontaneous combustion. In order to study the law of air leakage, taking the goaf of the third lower coal seam in Tengdong Shengjian Coal Mine as the research object, the goaf calculation model was established by GAMBIT software, and the dynamic characteristics of the air flow in the goaf were analyzed with the help of fluid simulation software FLUENT, the wind speed distribution in the goaf under different time conditions was simulated, and the flow field law was obtained.
