中文摘要：
基于冬瓜山铜矿深部出矿巷道其复杂的赋存条件和“高应力＋动力扰动”这的应力环境，巷道破坏严重，现行支护技术和方法不能满足需要。为保证矿山安全生产，有必要进行支护优化设计。针对接触带位于巷道顶板、侧帮2种工况提出不同支护优化方案，利用大型通用软件ABAQUS对优化方案数值分析，验证了优化方案的合理性，有效地控制巷道围岩变形，可供矿山巷道支护参考。
英文摘要：
Based on the fact that the ore - drawing roadway is seriously damaged and its current support techniques and methods can not meet the requirements due to its complex occurrence condition and stress environment of high stress with dynamic disturbance in Dongguashan Copper mine . In order to ensure the safe production, it is necessary to conduct optimization design of supporting structures. In view of two kinds of working conditions, which the contact zone is located in the roadway roof or side , putting forward different optimization scheme and using the finite element software ABAQUS to numerical analysis of the optimization program. It is verified that the optimized scheme is rational and the deformation of surrounding rock is effectively controlled. The conclusion can provide a reference for the mine roadway support.
