| 摘 要： | 采空区风流运动规律直接影响采空区乃至整个采场的瓦斯分布与涌动。以徐庄煤矿7335工作面为例，运用GAMBIT建立采空区多孔介质模型，流体力学软件FLUENT模拟采空区内流场，揭示了采空区漏风风速、压力的分布以及瓦斯在采空区内的运移规律，对保证煤矿的安全生产，提高矿井的经济效益有重要指导意义。

| Abstract: | The gas distribution and surge of the goaf and stope can be affected directly by the aire movement rule.The porous media model of goaf is established by GAMBIT,and the flow fileld in the area is simulated by yhe hydrodynamics software FLUENT,so as to reveal the speed of air leakage in goaf,the distribution fule of pressure,and the gas migration law in goaf.The research results in this paper is conducive to ensure safety procection of coal mine,and to improve economic benefit of mine. |
