基于组合赋权-改进可拓云模型的磷矿山岩性巷道围岩稳定性评价
Stability evaluation of surrounding rock of lithologic roadway in phosphate mine based on combination weighting-improved extension cloud model
摘要
Abstract
In order to accurately evaluate the stability of surrounding rock of lithologic roadway in phosphate mine,prevent the instability of surrounding rock,and effectively solve the problems of fuzziness and randomness in the process of surrounding rock evaluation,this paper proposes an extension cloud comprehensive evaluation model based on optimal cloud entropy improvement.Taking the panel ramp of No.2 Mine of Kunyang Phosphate Mine as the research background,five main sections were selected as samples to construct the evaluation index system of sur-rounding rock stability.The combination weighting of subjective and objective weights was completed by the minimum discrimination information principle,and the evaluation of surrounding rock stability grade was completed by combi-ning the improved extension cloud comprehensive evaluation model.The research results show that the stability of roadway surrounding rock in the slope of the panel is mainly between grade Ⅲ and grade Ⅳ.The evaluation results are consistent with the actual situation,and the accuracy of the evaluation results is higher than that of the traditional matter-element extension model.Based on the evaluation results,the corresponding support measures are put for-ward,which provides a scientific basis for the support design of lithologic roadway in phosphate mine.关键词
