摘要
本文通过对湖西矿井深井条件下回采巷道围岩变形观测及数值模拟,研究了超前巷道变形规律及锚杆预应力对围岩控制的效果,为现场围岩控制提供了依据,保证了安全生产,对于类似问题的研究具有指导意义。
According to on-site observation and numerical simulation study on surrounding rock deformation of deep mine in HuXi Coalmine, the Deformation Law of mining gateway and the effects of anchor prestress on surrounding rock control are researched, the basis for on-site surrounding rock control is provided, safety production is to ensured, valuable experience is provided for mines with the similar conditions.
