构造破碎带“三维”立体加固技术

3D reinforcement technology of tectonic fracture zone

基于某矿构造突水可能性大,危险大,水压高、含水层多等特点,为了达到巷道掘进面顺利通过断层的目的,采用"三维"立体加固技术对构造破碎带进行处理,选择适合该矿的注浆系统,并设计了合理的注浆工艺和注浆参数。结果表明,"三维"立体加固技术有效的改造了构造破坏带,解除了断层水害威胁,确保了巷道安全穿过断层,具有一定的实用价值,值得今后类似工程借鉴。

Based on the features that a mine has a large possibility and danger of water inrush, as well as its high water pressure, multiaquifer, in order to make tunneling surface get through the fault smoothly , 3D reinforcement technology has been used to deal with tectonic fracture zone. This article has analyzed the grouting reinforcement principle and designed reasonable grouting process and parameter. It shows that the 5D reinforcement technology has improved water-bearing structure fracture zone effectively, avoid the fault water disasters threat and ensure the tunneling surface get through the fault smoothly, and has a certain practical value.
