基于多目标模糊决策的二里河铅锌矿采矿方法优选

针对二里河铅锌矿矿体形态复杂、开采难度大、采矿方法难以选定的技术难题，先初选得出5种基本的采矿方案，在利用综合经济比较难以抉择的情况下，提出了多目标模糊决策方法优选采矿方法的思路：第一，分析了影响采矿方法选择的因素，利用层次分析法建立了采矿方法选择影响因素的隶属关系层次结构模型；第二，应用多目标模糊决策方法实现了采矿方法的优选决策，结合鞍部矿体和翼部矿体的赋存特点，得出了最优采矿方案和可行采矿方案。应用证明该方法在采矿方法的优选中是切实可行的，为确定矿山的合理采矿方法提供了一种新的技术手段。

Mining Method Optimization of Erlihe Lead-Zinc Mine Based on Multiple Target Fuzzy Decision

Aiming at the technical difficulties as complex Erlihe lead-zinc ore-body,refractory mining,hard to select mining methods etc.,five basic mining programs are primarily chosen.Due to the economic situation,the idea of multi-objective fuzzy optimization of mining methods is put forward: Firstly,the factors that affect the selection of mining method are analyzed,and a hierarchical structure model is built to determine the affiliated factors for choosing mining method by the hierarchical analysis method;Secondl...
