    Optimization of mining methods in a certain copper mine based on the AHP-FCE method

    • The optimization of mining methods is a kind of typical multi-objective decision problems. Its results directly effect mining operations and related engineering construction, even the economic benefits. In order to guarantee the sustainable development of a certain copper mine, transferring from open pit into underground mining, a comprehensive evaluation of three primary selected mining methods was carried out from the view of system engineering. Six indicators were overall considered by analytic hierarchy process, and their weight were defined scientifically and reasonably to establish index weight matrix. Simultaneously, a fuzzy relation matrix, indicating the fuzzy relationship between mining methods and indicators, was also established by applying fuzzy comprehensive evaluation method. Finally, comprehensive feudatory degrees of the three mining methods could be obtained by combine the index weight matrix and fuzzy relation matrix. Then, the mining methods can be ranked according to the value of comprehensive feudatory degrees. The ranking results show that double room and pillar method is the most suitable for underground mining of the copper mine.
