摘要: 对冬瓜山铜矿-760 m水平50线和52线采场底部结构巷道围岩变形进行了监测,采用累计位移和变形速率相结合对巷道围岩的稳定性进行分析,并采用巷道围岩稳定性指数对巷道稳定性进行了评价。

关键词: 多步骤回采, 底部结构, 稳定性评价, 围岩内部位移, 拱顶沉降

Abstract: The roadway surrounding rocks deformation of stope bottom structure of lines to 50 and 52 of -760 m level of Dongguashan copper mine are monitored.The cumulative displacement and deformation rate are adopted so as to analyze the stability of roadway surrounding rocks.Besides that,the stability of surrounding rocks of roadway is evaluated by roadway surrounding stability index.

Key words: Multi-step stoping, Stability evaluation of the bottom structure, Internal displacement of surrounding rocks, Vault subsidence
