Determination of optimal block size in angouran mine using VIKOR method

Size optimization of mining blocks is among the most important factors for optimal planning and systematic extraction in a mine. several technical and economic factors are effective in determining the size of mining blocks. the best size of blocks complies with geostatistical criteria appropriately and reasonably and is relatively favorable compared to other extractive,technical and economic criteria. in this regard,the use of multi-criteria decision-making methods is useful since it enables simultaneous consideration of the impact of several criteria with different relative importance. in this paper,while introducing a comprehensive suite of effective criteria to determine the optimal size of mining blocks using multi-criteria decision-making method of vikor,10-meter blocks were recommended as the best option (most appropriate size) for angouran mine.
