模糊综合评判模型在隐伏矿定位预测中的应用

Application of Fuzzy Comprehensive Appraisement Model for Location Prediction of Concealed Deposit

对于隐伏矿的定位预测,恰当的描述与处理不精确、非线性的控矿因素信息一直是困扰找矿工作者的难题。模糊数学用隶属函数来刻画元素对集合属于程度的连续过渡性,将经典集合的二值逻辑{0,1}扩展为[0,1]区间内的连续值逻辑。基于以上认识,本文利用模糊数学方法,结合AHP(层次分析法),建立了模糊层次综合评判模型,并用于对个旧矿区阿西寨测区5个异常区的综合评价研究。应用实例表明,该方法有效可行,能够给出合理的总体评价结论。

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 theory and AHP. The model has been used in predicting the locations of the mining units in Axizhai. The result shows that this model is valid in mining location prediction and it can give a good evaluation.
