摘要
以晋煤集团圣华煤业3#煤层复采工作面作为工程背景,应用FLAC3D数值模拟的方法对旧采窄残留煤柱中掘进巷道围岩破坏规律及其控制技术进行了研究。
Taking second mining of Jinmei Group Shenghua 3#coal seam old mining as a case study,FLAC3 Dnumerical simulation method of the old mining excavation in narrow pillar residue destruction rule of roadway surrounding rock and its control technology were studied.
