深露天矿的最终帮坡角取决于组成最终边帮的阶段数量、阶段平台宽度、阶段坡面角等因素。因此,在设计中应尽量加大阶段高度并提高其坡面角,最大限度地减少运输平台和安全平台的数目并缩小其参数。在实践中,尽管上述技术很复杂而且费用较高,但阶段坡面通常还是采用设计的倾 The ultimate slope angle of a deep open pit mine is determined by the number of stages, the width of the stage platform, and the slope angle of the stage that make up the final wing. Therefore, the stage should be designed to increase the height of the stage and increase its slope angle, to minimize the number of transport platforms and safety platforms and reduce its parameters. In practice, although the above techniques are complicated and costly, phase slopes are usually designed with dumping
