中文摘要：

随着浅部资源的逐步枯竭，某铜矿拟进行深部开采，针对3种回采方案建立模型模拟深部回采，结果表明：各回采方案的巷道开挖后的位移没有达到危险范围，回采进路顶板及两帮塑性区主要呈现拉伸屈服，其应力云图主要以压效应为主；对比3种方案，回采进路规格宜为4m×3．5m。

英文摘要：

With the gradual depletion of shallow resources, a copper mine plans to put forward deep mining. Therefore, mining models were established to simulate the deep mining according to three kinds of mining methods. The results showed that, the displacements in three schemes did not reach the dangerous range after drift excavation; the plastic zone in roof and two sides of the stoping drift mainly presented tensile yield, and the stress nephogram mainly presented pressure effect; compared the three schemes, the size of the stoping drift should he determined as 4 m×3.5 m.
