摘要
通过对上为破碎区、松散体,下为人工回填采空区的玲珑金矿大开头255塌陷巷道的复杂地质条件分析,运用水泥-水玻璃双液高压注浆插钢筋技术方案,对该塌陷巷道的复杂岩体进行改造治理,取得良好效果。
By analysis on the complex geological conditions of collapse tunnel in Dakaitou subsection of the Linglong Gold Mine, the upside of the collapse tunnel is fracture zone and filled with loose rock, and the bottom is worked-out section with artificial rock filled, the complex rock of the collapse tunnel is maintained by the technology of high pressure double pulp injection of cement-water glass with reinforcing bars, and the excellent result is achieved.
