摘要

矿山设计人员在选择合适的采矿方法时经常面临困难;但是,这种方法应该根据矿石和岩石的特性来选择。采矿方法的选择可以被认为是一种多准则决策,这取决于选择过程中使用的许多因素。该领域使用的一般方法是不列颠哥伦比亚大学(UBC)方法,该方法确定了比较属性的标准,以确定几种采矿方法的最佳和最差。本文采用了一种新技术,即理想解相似偏好排序技术(TOPSIS)。在UBC方法中考虑的标准包括一般形状、矿石厚度、矿石倾角和品位分布,以及岩石质量标识(RQD)和岩石物质强度(RSS)。本文提出了一种基于实验设计的改进TOPSIS方法。此外,本文还将介绍一种基于Excel表格的改进版UBC方法。最佳采矿方法为充填充填法和顶部分层法,采矿等级相同,为0.72;次优采矿方法为方形集采矿,采矿等级为0.65。

Selection mining methods via multiple criteria decision analysis using TOPSIS and modification of the UBC method
Mine designers often face difficulties in selecting an appropriate mining method; however, such a method should be selected based on ore and rock characteristics. The selection of mining methods can be considered a type of multi-criteria decision making, and this depends on many factors used in the selection process. The general method used in this field is the University of British Columbia (UBC) method, which determines the criteria of the properties that are compared to determine the best and worst of several mining methods. In this paper we used as new technique which define as Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). The criteria considered in the UBC method include general shape, ore thickness, ore plunge, and grade distribution, beside the rock quality designation (RQD), and the rock substance strength (RSS). This paper presents an improved TOPSIS method based on experimental design. Additionally, this paper will introduce a modified version of the UBC method that can be employed based on Excel sheet. The best mining methods is cut and fill Stoping and Top slicing with the same rank equal 0.72, and the second-best mining method is Square set Stoping with rank equal 0.65.
