摘　　要：鉴于岩爆倾向性评价的不确定性和模糊性,以模糊物元理论为基础,选取岩石强度脆性系数、强度应力比Rc/σ1、冲击倾向能WCF及岩石完整性系数作为评价指标,同时结合熵权理论及贴近度原则,建立了基于模糊物元理论的岩爆倾向性多指标综合评价模型,并将其应用于会泽锌铅矿8#矿体的岩爆预测中.结果表明该方法具有较好的合理性及适应性.In view of the uncertainty of indexes for evaluating rock burst proneness.Based on fuzzy matter-element theory,selected brittleness indexes,strength stress ratio,specimen length energy and crack density parameters as the evaluation index.couple with entropy value theory and close-degree principle,to establish a multiple attribute and comprehensive evaluation model for rock burst proneness.Used the modle for rock burst prediction of 8# orebody in Huize Lead-Zinc Mine,The results indicated that the proposed method is reasonable and practical.
