摘要/Abstract

摘要： 广西北山矿0 m水平巷道掘进过程中遇断层突水，为封堵富水断层在3个方向上对巷道的充水，采用巷道周边半封闭注浆法封堵涌水。由于断层裂隙带的裂隙发育极不规律，注浆孔涌水量差别极大，为保证注浆效果，针对不同涌水量的裂隙采用不同的水泥-水玻璃浆液配方。采用钻孔涌水量来估计该裂隙的注浆量，以此优化注浆参数和注浆施工工艺。最后采用检查孔法和注浆量分布特征法分析注浆效果，分析结果与巷道开挖后的实际结果一致。北山矿采用的注浆施工方法效果较好、工程量小、施工进度快，值得类似工程借鉴。

Abstract: Guangxi Beishan Ore suffered from water gushing when tunneling in 0 meter level.In order to prevent water flowing into tunnel from three direction，semi enclosed grouting method was applied to plug water gushing.Due to the highly irregular fault fracture，the rates of gushing water from drilling hole are different greatly.In order to ensure the grouting effect，different formula of cement-silicate slurry was adopted for fractures with different rate of gushing water.The flow of water in the borehole is used to estimate the amount of grouting in this fracture，in order to optimize the parameters of grouting and grouting construction technique.Finally，the effect of grouting is analyzed by the method of check-up hole method and grouting quantity distribution feature method.The results are consistent with the actual results after excavation.Anyway，grouting construction method in Guangxi Beishan mine is good with small project amount and fast construction progress，which is worth applying to the similar projects.
