【摘要】：基于规则块体品位模型和地表模型,使用锥体排除法产生地质最优境界序列和地质最优开采体序列.建立动态排序模型,对每个境界的地质最优开采体序列进行动态排序,使用动态规划方法以净现值最大为目标函数,找出最佳开采路径作为最优开采方案.根据每一个地质最优境界的最优生产计划选出净现值最大的境界作为最优境界,该境界的最佳开采路径作为最优生产计划,实现境界与生产计划同时优化.基于生态足迹理论构建矿山生态成本模型,结合各候选境界生产计划计算矿山生态成本,并纳入到露天矿境界中,使外生成本内生化,实现矿山项目评价和设计方案的"经济-生态一体化"优化.应用表明,生态成本对最终境界及矿山投资回报有重要影响.
[Abstract]:Based on regular block grade model and surface model, the conical exclusion method is used to generate geological optimal boundary sequence and geological optimal mining body sequence. A dynamic sorting model is established to dynamically sort the sequence of geological optimal mining bodies of each boundary. Using the dynamic programming method, the maximum net present value is taken as the objective function, and the optimal mining path is found as the optimal mining scheme. According to the optimal production plan of each geological optimal boundary, the maximum net present value (NPV) boundary is selected as the optimal boundary, and the optimal mining path of the boundary is taken as the optimal production plan, which realizes the optimization of both the boundary and the production plan. Based on the ecological footprint theory, the mine ecological cost model is constructed, and the mine ecological cost is calculated by combining the production plan of each candidate state, and it is incorporated into the open-pit mine boundary to make the exogenous cost endogenous. To realize the optimization of economic and ecological integration of mine project evaluation and design scheme. The application shows that the ecological cost has an important influence on the final state and the return on mine investment.
