Compromise solutions in mining method selection - Case study in Colombian coal mining

The purpose of this paper is to present a quantitative approach to the selection of the mining extraction method by developing a methodological problem of discrete multicriteria decision making (MCDM), this approach seeks to support the process of planning and mine design. Select the extractive method is one of the problems of Discrete Multicriteria Decision (MCDM) where decision-makers had problems in assigning weight to each criterion. To solve this problem, this article suggests the ENTROPY method. This paper wants to handle the subjectivity inherent to this problem by using the VIKOR method, which yields results in a compromise alternative. The methodology proposed in this article applies in coal deposit located in the western side of Cerro Tasajero in Norte de Santander, Colombia.
