榆树湾矿区大面积、深层采空区加固处理采用深层注浆、浅层加固,辅以地面变形观测和固定式横断面监测方法+监测中心计算机系统+通信传输平台的铁路预警系统的综合加固处理措施。深层注浆可防止采空顶板塌陷后,采空区上覆岩层形成跨落带、断裂带和弯曲带不会出现突然塌陷的可能;浅层加固则对采空区边界以外165～200m的变形区进行了加固处理,防止地表的横向水平变形和纵向水平变形对路基本体工程的影响;同时采用固定式横断面监测方法+监测中心计算机系统+通信传输平台的铁路预警系统观测网,对铁路后期运营提供了切实的保障。
The large area and deep goaf reinforcement treatment in Yushuwan mining area is carried out by deep grouting and shallow reinforcement combined with ground deformation observation and fixed cross-section monitoring method + Comprehensive strengthening treatment of railway early warning system by monitoring center computer system + communication transmission platform Measures. The deep grouting can prevent the overlying strata from forming in the overlying strata of the goaf after the roof collapses, and there is no possibility of sudden collapse in the fault zone and curved zone. For the shallow reinforcement, deformation of 165-200m beyond the boundary of the goaf Area reinforced to prevent the horizontal horizontal deformation of the surface and the longitudinal horizontal deformation of the basic subgrade project; At the same time the use of fixed cross-section monitoring method + monitoring center computer communication system + communication platform for early warning system of railway warning system, the late railway Operation provides a real guarantee.
