摘要
以华美奥兴陶煤矿42102工作面巷道设计为背景,介绍了近距离煤层煤柱支承压力下巷道矿压显现规律及支护方式,利用Flac3D数值模拟软件分析了煤柱引起的区域应力场分布特征,为类似条件下巷道支护提供借鉴依据。
With the roadway design of 42102 working face in Xingtao Coal of Huameiao Group as the background, this paper introduced roadway mine behavior law and support methods of coal pillar under bearing stress in the close distance coal seam and analyzed the regional stress field distribution characteristics caused by coal pillar by using Flac3D numerical simulation software, which provide reference basis for roadway support under similar conditions.
