基于耦合灰色关联度TOPSIS法的缓倾斜薄矿脉采矿方法确定

合理确定采矿方案对于新建矿山未来的健康发展极其重要。以山后矿区金矿为实证分析背景,综合TOPSIS法和灰色关联度理论,二者各自互补优势,构建了耦合灰色关联度TOPSIS法综合分析模型。基于3种常见开采缓倾斜薄矿脉的采矿方案,选取11个经济技术指标进行相对贴近度综合评价。研究结果表明:耦合灰色关联度TOPSIS分析模型计算得到的1、2、3采矿方案相对贴近度依次为37.65%、62.09%和46.08%,方案2(上向进路充填采矿法)最优。计算结果与TOPSIS法和灰色关联度法得到的贴近度进行了对比验证分析,吻合程度较好,验证了模型的合理性和科学性。

Mining method determination of gently inclined and thin vein based on coupling gray correlation degree TOPSIS method

Determination of mining method is very important for the development of a new mine. The comprehensive model using coupling gray correlation degree TOPSIS method was based on the practice of Shanhou Gold Mine, also synthesizing TOPSIS and Gray theory. Based on 3 mining methods for normal gently inclined thin vein, this paper selected 11 economic and technical indexes to evaluate the relative similarity. The results indicated that the relative similarity for mining methods 1 to 3 using coupling gray correlation degree TOPSIS model were 37.65%, 62.09% and 46.08% respectively. Method 2 (Overhand drift and fill stoping ) was proved to be the best. Comparing with the results of TOPSIS and Gray correlation degree methods, the goodness of fit was good, which verified the rationality and science of the model.
