Abstract
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.
Highlights
Hamrin (1986) defines underground mining as a technique of recovering minerals from deposits below the earth’s surface.Important indicators of underground mining, such as net efficiency production, excavation cost, ore losses, ore dilution and the final financial effects depend on selected and applied mining method
The aim of this paper is to demonstrate the implementation of an integrated approach that employs Analytic Hierarchy Process (AHP) and PROMETHEE together for selecting the most suitable mining method for the “Coka Marin” underground mine in Serbia
The selection of a suitable mining method for an ore deposit requires the consideration of a numerous criteria, such as mining-geological factors, economic factors and miningtechnical factors
Summary
Important indicators of underground mining, such as net efficiency production, excavation cost, ore losses, ore dilution and the final financial effects depend on selected and applied mining method. The most important goal of the applied mining method is the achievement of a lower excavation cost and a greater financial profit. The mining method selection cannot be solely based on these criteria. Ore excavation efficienc y and ore dilution are important characteristics of a selected mining method, which. Numerous considerations indicate that the undergorund mining method selection depends on the large number of relevant factors. These factors can be classified into three main groups, i.e.:
