摘要
针对庄上煤矿主斜井砌碹体破坏情况,提出了壁后高水材料注浆充填加固与锚杆锚索支护相结合的联合修复技术。工程实践表明:修复后该主斜井砌碹支护体整体性和承载能力得到了显著提高。
In view of the brickwork deformation situation of main incline shaft in Zhnangshang coal mine, puts forward the combined repair technology with high water quick-setting material grouting reinforcement, bolt and cable support. Engineering practice shows： after the restoration,the integrity and bearing capacity of the main incline shaft brickwork support has been greatly improved.
