The application of fuzzy comprehensive evaluation and Topsis approach to selection of optimum underground mining method

Usually, the optimistic method of underground metal mines is selected by some mathematic methods, empowered the safe, technical and economic indicators with weight. Due to make the selection of mining method more scientific and rational, Firstly, the Safe indicator is considered separately based on the perspective of corporate social responsibility and fuzzy comprehensive evaluation (FCE) method is used on the initial selection stage. Secondly, Entropy method is adopted to determine the weight of the related indicators on the final selection phase in case that the subjectivity of determining the weights happens. Finally, Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method is applied in selecting the optimistic method thorough an example and the results show it is scientific and effective.
