Selecting the best mining method among many alternatives is a multicriteria decision making problem. The aim of this paper is to demonstrate the implementation of an integrated approach that employs AHP and PROMETHEE together for selecting the most suitable mining method for the "Coka Marin" underground mine in Serbia. The related problem includes five possible mining methods and eleven criteria to evaluate them. Criteria are accurately chosen in order to cover the most important parameters that impact on the mining method selection, such as geological and geotechnical properties, economic parameters and geographical factors. The AHP is used to analyze the structure of the mining method selection problem and to determine weights of the criteria, and PROMETHEE method is used to obtain the final ranking and to make a sensitivity analysis by changing the weights. The results have shown that the proposed integrated method can be successfully used in solving mining engineering problems.A seleção do melhor método de mineração dentre muitas alternativas, é um problema de tomada de decisão baseado em múltiplos critérios. O objetivo do presente artigo é demonstrar a implementação de um enfoque integrado que adota AHP e PROMETHEE conjuntamente para a seleção do método de mineração mais adequado para a mina subterrânea "Coka Marin" localizada na Sérvia. O problema leva em consideração cinco possíveis métodos de mineração e onze critérios para sua avaliação. Os critérios são precisamente escolhidos de forma a incorporar os parâmetros mais importantes que impactam a seleção de métodos de mineração, tais como, propriedades geotécnicas, parâmetros econômicos e fatores geográficos. AHP é usado para a análise da estrutura do problema de seleção do método de mineração e para determinar pesos associados aos critérios. O método PROMETHEE é usado para determinar a classificação final e para fazer uma análise de sensibilidade através da variação dos pesos. Os resultados demonstraram que o método integrado proposto pode ser usado com sucesso na solução de problemas de engenharia de minas.

The selection of optimal technology for surface mining of mineral deposits is a standarddecision-making problem. The aim of this paper is to demonstrate the potential of thecombined AHP and ELECTRE methods in selecting the optimal technology usingthe open pit coal mine “Ugljevik East” (Ugljevik Istok) as an example. In order toresolve the problems encountered, the three types of technologies were taken intoconsideration with regards to the eight criteria for selecting the optimal solution. Thecriteria include the most important aspects of selecting the optimal technologies, suchas geology and geotechnical engineering, ecology, economy, etc. In addition, AHP isused to analyse the structure of the technology selection process and to determine thesignificance and impact of certain criteria in the selection process, while ELECTREmethod is used for the final ranking of alternatives. The obtained results indicate thatthe proposed combined method provides extraordinary results and that it can be used toresolve various, even the most complex problems that occur in mining engineering.
