Abstract:

Abstract：The article studied the mining process of residual water bench in open-pit mine. Taking Yimin Open-pit Mine as example, through try and optimization of residual water bench mining in east slope, the author obtains general rules of mining layer based on aquifer distribution. Through researching shovel mining east slope bench process in Yimin Open-pit Mine, the author summarizes a set of effective mining way of bench.
