Ranking the efficiency of selected platinum mining

Four mining methods were compared on the basis of 49 attributes clustered into five decision criteria. De Almeida, Alencar and PROMETHEE II used to select the mining method for ornamental rocks that best satisfies a set of evaluation criteria. de Miranda (2005) Six mining methods were compared on the basis of five criteria. Liquin, et The benefits of ore blending are extending the ore reserve base by utilization of low-grade, minimizing the need for selective mining hence reducing mining costs and increasing mine production(PDF) A Method of Ore Blending Based on the

Underground mining method selection by decision making

In real life, underground mining method selection is one of the multiple attribute decision making (MADM) problems and decision makers have always some difficulties in making the right decision in the multiple criteria environment. Analytic hierarchy process (AHP) and Yager’s methods are the MADM tools and can be used for selection Examples of these new methods can be found in many mines in China, such as Hexi Gold Mine (Wang et al. 2003), Wangershan Gold Mine (Ding et al. 2014), Outside China, the traditional room-and-pillar method is applied in Tweefontein Chrome Mine of South Africa’s Samancor region.
