Abstract: Selection of mining method plays a very important role in mine production.How to optimize the mining method has been always concerned by the designer.Fuzzy mathematics theory and AHP are used to realize the selection of mining method and optimize the mining method selection system under two and three-dimensional integrated environment.Several aspects of architecture design，functional modules of the system analysis，system database functions and the achievement of system are elaborated.The application of the system can effectively improve the efficiency and accuracy of selecting mining method，and reduce the subjectivity of human judgment，thus effectively reduce the production and operation costs in mining process，and improve the efficiency of mine enterprises.

Key words: Two and three dimensional integration, Fuzzy mathematics, Mining method, Optimized selection, Expert system
