摘要: 基于开采总利润最大的准则,设计了开采境界优化的“正锥体排除法”算法体系,包括最大境界的圈定,锥壳模板构建和锥体排除算法.该算法可以方便地处理不同方向和区域具有不同帮坡角的情况.把这一算法体系应用于建立的柱状煤层模型,根据矿山生产能力、煤矿地质条件、当前煤矿开采成本以及煤矿售价,进行优化,得出了在给定煤层赋存条件和技术经济条件下境界的最佳大小和形态,以及采剥量.为矿山生产决策者提供了设计依据,具有重要的参考价值.

Abstract: Based on the principle of profit maximization, the upright cone algorithm was designed to optimize ultimate boundary of openpit coal mine. The algorithm is to delimitate largest boundary, to construct cone shell template and to exclude cones. It could easily incorporate different finalslope angles in different directions and zones. According to the production, geological condition, mining cost and coal price, the algorithm was used on the columnar coal seam model to optimize boundary. Under the geological condition of coal seam, including technical and economic conditions, the optimum size and shape of boundary as well as stripping quantity was obtained. The optimization results provide great reference for the policy makers.

Key words: openpit coal mine, boundary optimization, cone exclusive method, cone shell template, ultimate boundary
