本文在分析了露天矿山境界圈定的浮动圆锥法及动态规划法以后提出了一种露天矿境界圈定优化设计程序——剖面组合法。一个露天矿境界是由若干个横剖面及两个端帮组合而成。每个端帮亦可分割成若干个横剖面,每个横剖面按所给定的边坡角及采场底最小宽度等条件,根据矿体形态及地形地貌,用图解法求出该剖面的开采范
After analyzing the floating cone method and the dynamic programming method delineated in the open-pit mine, this paper presents a method of delineation and optimization of the open-pit mine delineation-profile combination method. An open pit realm is composed of a number of cross-sections and two end gangs. Each end can also be divided into a number of cross-section, each cross-section according to the given slope angle and minimum width of stope and other conditions, according to the ore body morphology and topography, Mining Fan
