特殊地质条件下巷道修复加固技术适配性研究与应用

Research and Application on Adaptability of Roadway Repair and Reinforcement Technology under Special Geological Conditions

针对山东省辖区内埋深千米深井岩石巷道及硐室受地压及赋存条件的影响,反复性发生明显变形及支护失效现象,主要通过矿压监测、岩石物相化验分析相结合的综合研究方法,采用预注浆再生围岩支护机制,建立了完善的巷道修复控制系统,提出了特殊地质条件下巷道修复施工围岩稳定性控制的"三锚一带"联合支护技术,形成修复加固的高效经济性施工方案,具有较强的适应性和推广性。

According to the influence of ground pressure and occurrence conditions on rock roadway and chamber of kilometer deep well in Shandong Province,obvious deformation and support failure occur repeatedly.The comprehensive research method of combining mine pressure monitoring and rock facies analysis is mainly adopted,and the support mechanism of surrounding rock regeneration by pre grouting is adopted,This paper establishes a perfect control system of roadway repair,puts forward the"three anchors and one belt"combined support technology of surrounding rock stability control in roadway repair construction under special geological conditions,forms an efficient and economic construction scheme of repair and reinforcement,which has strong adaptability and popularization.
