伊犁一矿巷道围岩属于西部弱胶结软岩,具有强度低、胶结差等特性,应用岩石物理力学测试结果,配合地应力空间分布情况,在分析该矿主斜井围岩变形破坏的原因的基础上,提出了“适度让压、强化支护、耦合变形、主被动支护相结合、关键部位补强”的新支护理念,通过该支护理念指导巷道开挖、支护工艺,在实践生产过程中取得了良好的支护效果,最终实现了巷道的稳定性控制。
伊犛一礦巷道圍巖屬于西部弱膠結軟巖,具有彊度低、膠結差等特性,應用巖石物理力學測試結果,配閤地應力空間分佈情況,在分析該礦主斜井圍巖變形破壞的原因的基礎上,提齣瞭“適度讓壓、彊化支護、耦閤變形、主被動支護相結閤、關鍵部位補彊”的新支護理唸,通過該支護理唸指導巷道開挖、支護工藝,在實踐生產過程中取得瞭良好的支護效果,最終實現瞭巷道的穩定性控製。

Roadway surrounding rock in Yili No.1 mine belongs to the weakly consolidated soft rock in western and has the characteristics with low strength and poor cement. As applying the results of the rock physical-mechanical properties research and combined with in-situ stress spatial distribution, a new support concept with “moderate release the pressure, enhanced support, coupling deformation, combination of active and passive support, key position reinforcement”was introduced on the basis of analyzing the main cause of deformation and failure of surrounding rocks in inclined shafts. In the process of practice production it brings good supporting effect through applying it in conducting roadway excavation, support technology. The roadway stability control can be achieved ultimately.
