摘要
基于羊渠河矿区的地应力分布和各岩层的岩石力学性质,针对52回风上山,提出了新的高强高预紧力锚杆深部支护设计方案,通过数值模拟对比了新旧支护方案的支护效果。研究结果可为羊渠河矿区深部支护提供科学合理方案。
Based on geostress distribution and lithological properties of rock strata of Yangquhe Mining Area,this paper put forward a new design project for supporting deep roadway with high strength and high pre-tightening anchored bolt.Supporting effects of old and new design were compared by numerical simulation.The result may provide scientific and rational project for supporting deep roadway in Yangquhe Mining Area.
