摘要： 为了解决新景矿开采9#煤层过程中，受采动影响上邻近层6#煤层中的瓦斯大量涌向工作面，严重影响工作面
安全生产的问题，以新景矿9304 工作面为工程背景，经过现场调研分析，最终确定采用上邻近层大直径钻孔瓦斯抽采方
案。实践证明，该方案在工作面推进过程中取得了良好的效果，有效降低了9304 工作面的瓦斯浓度，为其他工作面的开
采提供了借鉴意义。

Abstract: During the mining of 9# coal seam in Xinjing Coal Mine, gas gushed into the working face in the upper adjacent 6#
coal seam under the influence of mining, seriously affecting the safe production of the working face. In order to solve the problem,
taking 9304 working face of Xinjing Coal Mine as the engineering background, this paper finally determined the gas extraction
scheme of large diameter borehole in upper adjacent layer through field investigation and study. Practice shows that the scheme
has achieved good results in the process of advancing the working face, effectively reducing the gas concentration of the 9304
working face, providing reference for the mining of other working faces.
