摘要
针对某矿西翼运输大巷围岩变形严重问题,对巷道围岩变形机理进行了分析,针对性地提出了采用高强度锚网喷支护+帮部二次锚网梁索的综合支护技术,现场矿压观测结果表明,采用该支护技术能够有效控制巷道围岩的稳定性。
The West Wing in a mine transportation roadway surrounding rock deformation serious problems, analyzes the deformation mechanism of roadway surrounding rock, proposed using high strength anchor cable combined support ＋ help two anchor cable network support technology, field observation of mine pressure. The results show that the supporting technology can effectively control the stability of surrounding rock.
