基于信息熵与模糊决策理论优选采矿方法

Optimization of Mining Method Based on Information Entropy and Fuzzy Decision Theory

根据铀矿山地下开采具有模糊性和层次性的特点,结合结构熵权法理论,形成主观与客观相结合的权重确定方法。应用模糊优选法理论,确定各方案关于优的相对隶属度,得出各采矿方法的优劣顺序。工程应用表明,优选出的采矿方法具有较强的适用性,在采矿成本方面有明显优势。基于信息熵与模糊决策理论优选采矿方法是可行的,既可反映工程实际情况,又能减少经验评估法的主观性与随机性,可为铀矿山选择采矿方法提供技术支持。

According to the of underground mining of uranium mine which has the characteristics of fuzziness and hierarchy,combined with the structure entropy theory,subjectivity and objectives method to determine the weight value of each factor was formed.Application of fuzzy optimization method to determine the relative merit degree of the each scheme,then,the good and bad sequence order is obtained.Through engineering application verification,the optimization mining method has very good applicability,which shows obvious advantage in mining cost aspect.The optimization mining method which is based on information entropy and fuzzy decision theory is feasible,it can not only fully reflect the actual situation of engineering and but also reduce the subjectivity and randomness in the selection of mining methods.The optimization mining method can provide technical support for uranium mine to selection of the mining method.
