The filling mining method was used instead of nonpillar sublevel caving to mine the constructed over ore body to ensure safety in the operation of a beneficiation plant of Chenchao Iron Mine.The optimal filling mining method was determined by introducing the Systems Engineering analysis method.In order to guarantee objectivity and scientificity of the evaluation results,a method of analytic hierarchy process in combination with fuzzy comprehensive evaluation was employed to optimize the three alternative filling mining methods.Six technical and economical indicators were overall considered by analytic hierarchy process,and their weights were defined scientifically and reasonably by three sign degree.A fuzzy relationship between mining methods and indicators was established by applying fuzzy comprehensive evaluation method.Comprehensive feudatory degrees of the three mining methods could be obtained by combining the index weight matrix and the fuzzy relationship.Then,the mining methods can be ranked according to the value of comprehensive feudatory degrees.The ranking results showed that the filling-up method is the most suitable for the constructed over ore body in Chenchao Iron Mine.
