地下金属矿山回采方案优化设计新技术及其应用

从指导思想、采用的手段、工具和方法等方面对地下金属矿山回采方案优化设计技术现状进行了深入系统的分析和评述,给出了理想的地下金属山回采方案优化设计技术——全盘全过程的优化设计,提出模型构建及方案实施效果的计算机模拟是其中的核心问题.采用这种全盘全过程的设计路线,可以改变传统的以专家经验和直觉判断、定性分析为主的回采方案优化设计模式,提高回采方案设计的科学性、实施效果的可预知性和可调控性,使矿山的管理和决策模式发生由经验到科学、静态到动态、分散到集中、杂乱到系统、缓慢到快速的根本性转变.结合冬瓜山铜矿的实际问题,进行了该技术的应用,确定了冬瓜山铜矿最优回采顺序的选取原则及其充填系统完成时间.

New Optimization Design Techniques of the Mining Schemes for Underground Metal Mine and Its Application

It is shown that the traditional optimization methods for the mining schemes of underground metal mine are not very accurate and fall short of the modern mining requirements. This paper proposes a new ideal optimization method, that is comprehensive, quantitative, and takes account of the whole implementation process. The resources and mining environment modeling and the mining process simulation are the key elements ofthis method. With this new method, not only the optimal scheme is obtained, but also the ...
