It is a big puzzle for mining-searching for experts to well predict the locations of the hidden mines, to appropriately describe and to deal with the imprecise and nonlinear information of mineralization all over the world. In this paper, fuzzy mathematical conception and theory was discussed firstly. The subject function was used to describe the continuous transition of the elements belonging to a set. The two value logic { 0,1 } in classic set is extended to a continuous value logic in a [ 0,1 ] zone. Then a fuzzy comprehensive evaluation model was built up by combined fuzzy mathematical the...
