Research And Application Of Ahe Forecasting Method Based On Fuzzy Evidence Right In Ahe Search For Distant Scenic Spot

With the ore prospecting target from the outcrop mine to the hidden mine, from the shallow table to the deep, the difficulty is more and more difficult to find. Therefore, the innovation of the theory, method and technology of mineral exploration and prediction has attracted much attention in the field of international mining industry. The method of evidence right is one of the most widely used methods in the field of mineral resources, such as quantitative prediction, environmental assessment, geological hazards and so on. Is one of the recommended methods of national mineral resources potential evaluation project in China. The logical information method is proposed by the former Soviet Union scholar, the method is based on mathematical logic analysis method, combination analysis and mathematical statistics based on a comprehensive mathematical. Two state assignment method of logic information method and the right of the traditional evidence, can make use of the uncertain information. Fuzzy weights of evidence is in the weights of evidence method cannot handle uncertain information and improved on the basis, with uncertain information using the three state or polymorphic assignment. Inspired by this, in this paper, the traditional logical information method from the second state assignment improved assignment for the three state, thus the uncertain information be used.Based on the weight of evidence, fuzzy weights of evidence, the traditional logical information amount of three kinds of prediction methods and three state logic information method respectively to Mira hill copper self-contained exploration area to ore prospecting and prediction. Then the three state logic information method to derive the prediction effect and evidence weight method and traditional logical information method prediction effects were compared. The results showed that the three state method in uncertain information utilization, variable selection and ore no ore unit discrimination than the traditional logic information method is more reasonable and accurate and predictive results and Mira hill copper self-contained consistent exploration area actual size of ore deposits, indicating the feasibility of three state logic information method.
