在坎曼图(Kanmantoo)露天矿开采初期产生局部滑坡之后,重新设计了西帮边坡,将运输线路之间的总体边坡角从55°改作46°。这一决定是基于概率统计分析方法作出的,分析表明,46°为最优的经济边坡角。
After a localized landslide in the initial mining of the Kanmantoo open-pit mine, the western slope was redesigned to change the overall slope angle between the transport lines from 55 ° to 46 °. This decision was based on a probabilistic statistical analysis that showed 46 ° as the optimal economic slope angle.
