摘　　要：通过对采煤后覆岩裂隙形态的分析,根据采煤工作面瓦斯流动特征,获得采动影响下瓦斯地面井布置基本原则。结合覆岩移动规律及钻井井身结构变形破坏特征,设计了采动影响下瓦斯抽采地面井井身结构,并在晋煤集团岳城矿进行了应用,取得较好的瓦斯抽采效果,解决了采煤工作面瓦斯超限问题,为煤矿安全生产提供了保障。Through the analysis on crack form of overburden rock after mining and according to the gas movement characteristics in the working face,the layout principle of the surface gas drainage well under the influence of mining was obtained,based on the movement regularity of overburden rock and the deformation and failure characteristics of surface gas drainage well,the structure of the surface gas drainage well affected by the mining was designed,which was applied in Yuecheng Mine of Jincheng Anthracite Mining Group,better gas drainage effect was obtained,and the problem of gas overrun in the working face was solved,this thus provided guarantee for safe production of the mine.
