| 摘 要： | 以宁夏固原银洞沟矿地质条件为背景,通过运用有限差分软件(FLAC)对U型棚-锚杆-锚索联合支护方案进行模拟,采取一种主动+被动联合支护形式.通过模拟对联合支护方案的可行性进行分析,以研究围岩变形、巷道顶底板和两帮的变化量来判断围岩的稳定性,进而为工程施工提供有利的指导意见.

| Abstract: | Based on the geological conditions of the Silver Cave Trench Mine in Ningxia Guyuan,this paper simulates the joint support scheme of U-shaped shed-anchor-anchor rope by using finite differential software(FLAC),which is an active-passive joint support form.By simulating the feasibility of the joint support scheme,the stability of the surrounding rock is judged by studying the deformation of the surrounding rock,the top plate of the roadway and the amount of change of the two gangs,and thus provides favorable guidance for the construction of the project. |
