摘要
为提高地下金属矿山巷道围岩稳定性评估的准确性,根据工程实际,选取 5 个典型影响因素,构建了围岩稳定性评价指标体系,运用区间层次分析法(Improved Analytic Hierarchy Process,IAHP)和改进 CRITIC 法(Criteria Importance Though Intercrieria Correlation,CRITIC)分别计算指标主、客观权重,基于博弈论思想,确定指标最优综合权重,结合多维联系云模型理论,建立了地下金属矿山巷道围岩稳定性综合评价模型.以国内 14 条巷道工程为样本数据进行模型检验,并与模糊综合、物元可拓判别结果及实际情况进行对比.最后,将模型应用到某金矿巷道围岩稳定性评估中.结果表明,基于博弈论-多维联系云的地下金属矿山巷道围岩稳定性评估结果与现场调查结论完全一致,验证了本模型在巷道围岩稳定性评价方面具有可行性和有效性,可以为地下金属矿山巷道围岩稳定性评估提供一种准确的、可量化分析的新思路.
Abstract
In order to improve the accuracy of surrounding rock stability assessment in underground metal mine tunnels,based on engineering practice,five typical influencing factors were selected to construct an evaluation index system for surrounding rock stability.The improved Analytic Hierarchy Process and the improved CRITIC method were used to calculate the subjective and objective weights of the indicators,based on game theory ideas,A comprehensive evaluation model for the stability of surrounding rock in underground metal mine tunnels was established by determining the optimal comprehensive weight of indicators and combining it with the theory of multidimensional connection cloud model.Using 14 domestic tunnel projects as sample data for model verification,and comparing them with fuzzy synthesis,matter element extension discrimination results,and actual situations.Finally,the model is applied to the stability evaluation of the surrounding rock of a given gold mine roadway.The research results show that the stability evaluation results of underground metal mine roadway surrounding rock based on game theory multi-dimensional connection cloud are completely consistent with the conclusions of on-site investigation,verifying the feasibility and effectiveness of this model in evaluating the stability of roadway surrounding rock.It can provide an accurate and quantifiable new approach for evaluating the stability of underground metal mine roadway surrounding rock.
