摘要
通过深入分析赵各庄矿深部高应力软岩巷道围岩变形机理,提出了采用喷锚注技术进行修复,并根据巷道实际情况设计了支护参数,有效地控制了围岩变形,保证了巷道的稳定,取得了良好的技术经济效果。为类似巷道支护提供了可借鉴的经验。
Through a thorough analysis of Zhaogezhuang mine deep high stress soft rock roadway surrounding rock deformation mechanism, put forward by spraying anchor technology to repair, and according to the actual circumstance of tunnel design of supporting parameters, to effectively control the deformation of surrounding rock, ensure the stabilization of the roadway, and achieved good technical and economic effect. Provide reference for the similar roadway provides the experience that can draw lessons.
