摘　　要：以鹿洼煤矿4301工作面为研究对象,利用fluent数值模拟软件理论上研究回采过程中工作面和采空区瓦斯体积分数分布规律,得到了整个采场瓦斯体积分数立体分布云图;分析了采场瓦斯体积分数沿走向倾向的分布情况;并比较了不同风速情况下瓦斯体积分数分布变化情况,从而为工作面的高效安全回采提供指导。Taking No.4301 face of Luwa Coal Mine as the research object,the numerical simulation software was used to study the gas concentration distribution of the face and goaf while stopping.And the three-dimensional map of the gas concentration distribution in the whole stope was obtained.In addition,the situation of the gas concentration distribution along the tendency to the stope was analyzed.The variation of gas concentration distribution in the different wind speed were also compared.It would be prudent to provide some guidence in order to determine the safety and efficiency of the face in the stopping.
