摘要
针对临空煤巷受回采期间动压影响大、围岩破碎变形严重的问题,通过数值模拟对其变形破坏机理进行分析,并将注浆技术用于破碎围岩加固,通过工业性试验,满足了现场正常安全生产的要求。
In view of the influence of dynamical mining pressure on goaf-side haulageway and the serious deformation of broken surrounding rock in mining period,the paper introduces the application of grouting technology in the reinforcement of broken surrounding rock by analysis of the deformation failure mechanism through the numerical simulation,which meets the requirements of the normal safety production site through industrial test.
