摘　　要：针对金厂河多金属矿大直径深孔采场顶板围岩连续破碎、失稳垮塌、压覆资源等技术难题,对29#采场开展顶板支护方案优化设计的工业试验。现场应用表明支护结构能够承受采动应力的变化,有效控制了顶板变形,起到良好的锚固效果。Technical difficulties such as continuous crushing,unstable collapsing,and resource overlaying affect the roof surrounding rock of the large diameter deep hole stope in Jinchanghe polymetallic ore.To address the mentioned issues,an optimal design for an industrial test of a roof retention and protection system was developed for the 29#stope.On-site applications indicate that this retaining and protective structure can withstand changes in mining stress,effectively controlling roof deformation and providing improved anchoring performance.
