摘 要:长平矿底抽巷顶板及两帮为泥岩层,裂隙发育且易风化,围岩稳定性极差。为解决顶板及矿压治理问题,创新采用薄层喷涂快速封闭技术。研究表明,该技术能够有效防止巷道顶板及两帮泥岩风化、破碎,保证围岩的整体完整性,控制巷道围岩变形,降低巷道维修工程量。The roof and two sides of the bottom extraction roadway in Changping Mine are mudstone layers,with developed fissures and easy weathering.The stability of the surrounding rock is extremely poor.In order to solve the problems of roof and mine pressure control,a thin layer spray rapid sealing technology is innovatively adopted.The research shows that this technology can effectively prevent the weathering and fragmentation of the roadway roof and two sides of mudstone,ensure the overall integrity of the surrounding rock,control the deformation of the roadway surrounding rock,and reduce the amount of roadway maintenance work.
