中文摘要: 为解决大尹格庄金矿深部复杂应力环境下围岩破碎巷道的支护问题,根据现场实际情况,分析破碎围岩巷道变形破坏规律,提出应用玻璃钢锚杆与管缝锚杆联合支护技术为核心的支护结构。经过理论分析和数值模拟计算,确定了合理经济的支护参数和新的支护方案,能够显著地提高围岩的强度和承载能力,有效地控制破碎围岩巷道的围岩变形,为解决类似工程难题提供了有效途径。
Abstract:In order to solve the support problem of cracked surrounding rock roadway in the deep complex stress environment of Dayingezhuang gold mine, taking the actual situation of the site into account, this paper analyzed the deformation and failure regularity of cracked surrounding rock roadway, and proposed a kind of support structure with the joint support technology of GFRP anchor and Split-set bolt as the core. Through theoretical analysis and numerical simulation calculation, the reasonable and economic support parameters and new support scheme were determined, which can significantly improve the strength and bearing capacity of surrounding rock, effectively control the deformation of surrounding rock of cracked surrounding rock roadway. This research can provide an effective method to solve similar engineering problems.
