Abstract [en]

This paper presents a new approach for estimating unknown ore grades within a mining deposit in a fuzzy environment using fuzzy c-means clustering and a fuzzy inference system. Based on a collection of cluster centers obtained from fuzzy c-means, a fuzzy rule base and fuzzy search domains are established to compute grades at these cluster centers. These cluter center-grade pairs act as control information in the fuzzy space-grade system in order to infer unknown grades on the basis of fuzzy interpolation, fuzzy extrapolation, and a defuzzification process of fuzzy control.
