Abstract: Whether the mining method is rational or not will have great impact on the economic benefit of mining enterprise. To improve the engineering analogue method in the selection of mining method, the paper describes the principle, procedure, characterization of membership function and determination of weight coefficient of using fuzzy mathematics in the selection of the optimal mining method for Moping Gold Mine. The forecasted indexes have been verified in the production practice, indicating that fuzzy mathematic method is feasible here.

Key words: Fuzzy mathematics, Optimal choice of mining method, Membership function
