通过对有向图论法、动态规划法和多重移动锥法的实际工作及理论分析,提出了一种用计算机确定露天矿最优境界的新方法。该方法的特点是澄清剖面上矿块所发生的单位闭包(或圆锥)的联合影响,采用二维动态规划法来寻找可采闭包。于是,所有可采闭包的叠加就给出一个最大闭包——最优露天坑。和其它方法相比,本方法可考虑多个变化的边坡角,且能用小型计算机迅速获得最优露天矿境界。文中给出一个应用计算机设计露天矿的实际例子。
Through the practical work and theoretical analysis of directed graph theory, dynamic programming method and multiple moving cone method, a new method of determining the optimal realm of opencast mine by computer is proposed. The method is characterized by the combined effect of unit closures (or cones) that occur on the mineral blocks in the cross-section, and a two-dimensional dynamic programming approach to find recoverable closures. Thus, the overlay of all recoverable closures gives a maximum closure - the optimal open pit. Compared with other methods, this method can consider many different slope angles, and can quickly obtain the optimal open-pit realm with a small computer. The article gives a practical example of using computer to design open pit mine.
