基于模糊综合评判法的某铀矿井开拓方案选择OA

The selection of mine development plans is a complex process involving multiple factors and indica-tors.In order to reduce the influence of subjective judgment on the selection of mine development plans,taking a uranium mine well as the research object,a fuzzy comprehensive evaluation model was established based on the fuzzy mathematics theory,the fuzzy weights of 10 influencing factors were determined,and the influence degree of the development plan was quantified.Based on the fuzzy judgment weight matrix and the relative membership degree matrix,and in accordance with the principle of fuzzy mathematics comprehensive evaluation,the optimal development method is determined from the initial development schemes of fuzzy clustering.Through fuzzy com-prehensive evaluation,the optimal main and auxiliary shaft development schemes are determined as the vertical shaft and vertical shaft development scheme.According to the different hoisting methods of the mines,a techni-cal and economic comparison was conducted on the two proposed schemes.The comparison results recommend that the centralized hoisting schemes of the two mines be adopted as the mine development schemes.
