露天采矿排岩系统的线性规划法研究及其应用

Research and application on linear programming method of open-pit mining rock dumping system

排岩工程是露天矿开采极其重要的一环,在矿山开采时排岩成本所占比例很大,直接影响经济效益,因此,设计和优化排岩方案是矿业工程中面临的一项重要课题。通过建立总体线性规划模型和短期线性规划模型,考虑到相关约束条件,得出露天采矿生产中可行的动态控制方案,验证了线性规划法在露天采矿排岩系统中的科学性和有效性。

Rock dumping engineering is an extremely important part of open-pit mining, which account for a large proportion in rock dumping cost, impacting direct to economic benefits. Therefore, the design and optimization of rock dumping engineering program facing an important subject, considering the relevant constraints, the paper establish general and short-term linear programming model which is feasible dynamic control scheme in the process of open-pit mining production, verifying the linear programming method is scientific and effective in open-pit mining rock dumping system.
