摘　　要：文章以五阳煤矿7802综放工作面的具体条件为基础,建立数值分析模型;运用计算流体动力学软件FLUENT对采场瓦斯运移规律进行模拟,并对工作面不同风障设置情况进行对比分析。模拟分析结果显示该工作面目前为治理上隅角瓦斯积聚超限所采用的风障设置方式存在漏风严重及上隅角瓦斯治理不彻底的不足,从而针对该工作面风障设置方式提出改进措施,并运用数值模拟的手段验证了改进措施的有效性。In this paper,based on the specific conditions of 7802 working face in Wuyang Coal Mine,establishes the numerical analysis model.A CFD software of FLUENT is adopted to simulate the gas delivety law in the stope,and different situation of windbreak settings is established to contrastively analyse.It is showed in the simulation result that at the settings of windbreak at working face adopted presently exists disadvantages of wind leaking out gravely and upper corner gas controlling not drastically.Thus the improved measures in view of this situation are proposed,and by numerical simulation the improved measures is proved feasible and efficient.
