摘要
考虑到采矿方法优选的复杂性,建立了基于G1法和GRA-TOPSIS的采矿方法优选模型.以山东省内某缓倾斜厚大矿体为研究对象,初选了3种采矿方案,构建了采矿方案优选评价指标体系,利用G1法为指标赋予权重,基于GRA-TOPSIS原理,通过计算灰色关联贴近度,确定各采矿方案的优劣性排序,结果显示方案Ⅰ为最优方案,优选结果符合工程实际,满足了预计需求.
Abstract
There are many factors that affect the selection of mining methods.A mining method optimization model based on G1 method and GRA-TOPSIS was established to achieve comprehensive scientific judgment of multiple mining schemes.Taking a gently inclined thick and large ore body in Shandong Province as the research object,three mining plans were preliminarily selected.Based on the construction of the evaluation index system for mining plan optimization,the G1 method was used to assign weights to the indicators,and the GRA-TOPSIS principle was used to calculate the grey correlation closeness degree to determine the ranking of the advantages and disadvantages of each mining plan.The results showed that Plan I was the optimal plan,and the optimization results were in line with engineering reality and met the expected needs.
