摘要: 某铁矿基建竖井-50 m水平马头门及巷道位于含水泥质灰岩夹褐铁矿层中,因矿层上部有河床,河水顺导水断层进入矿区,造成施工被迫中断。为防治该断层导水,经现场勘察,对该水平的竖井马头门及部分巷道采用帷幕注浆工艺进行了涌水封堵,快速通过含水带,取得了良好的效果,为同类工程施工提供了借鉴。

Abstract: An iron mine infrastructure shaft -50 m level horse head Door and roadway are located in the cement-bearing limestone-bearing limonite layer.Because there is a riverbed in the upper part of the ore layer,the river water and water-conducting faults enter the mining area,causing the construction to be interrupted.In order to prevent and control the fault water guide,through the site investigation,the horizontal head horse head door and part of the roadway were sealed by gushing water by curtain grouting technology,and the water belt was quickly passed.It has achieved good results and provided reference for the construction of similar projects.
