摘要
为了研究露天矿复合边坡几何结构的发展规律,基于开挖-堆载的基本工程步骤,推导了开采作业过程中开挖工程量的计算公式,并根据开挖方量推导出均匀排弃时排土场高度计算公式,结合安太堡露天矿的基本参数及排土场的实际排弃方式,得出了该露天矿外排土场高度变化规律曲线。
In order to research developing law of compound slope geometry structure in open-pit mine, the article deduces the calculation formula of excavation quantities in the process of mining operations based on basic engineering step of excavation- heaped load.According to excavation volume, it deduces the calculation formula of dump height in even discharge, and obtains height variation curves in the open-pit mine external dump combining the basic parameters and actual discharge mode of dump in Antaibao open-pit mine.
