谦比西铜矿矿岩稳定性的模糊物元评价

基于模糊物元理论，选择合理的岩石稳定性评价指标，通过隶属度计算，建立了岩石稳定性评价的模糊物元模型。为避免权重确定的主观性，采用求和归一法来确定评价指标的综合权重，最后根据关联度计算结果及最大关联度原则，实现了对谦比西铜矿井下围岩稳定性等级的多指标综合评判。结果表明：采用模糊物元理论进行岩石稳定性评价是有效可行的，为岩体稳定性评价提供了一条新的思路。

Fuzzy Matter-element Evaluation for Ore-rock Stability in Chambishi Copper Mine

Based on the fuzzy matter-element theory，a reasonable evaluation index of rock stability is chosen，and the fuzzy matter-element model of rock stability is finally built through the calculation of membership. In order to avoid the subjectivity of weight determination，the sum normalization method is adopted to determine the comprehensive weight of evaluation index，and then according to the calculating result of membership and the principle of maximum correlation degree，the multi-index comprehensive evaluation of stability grades for underground surrounding rock of Chambishi Copper Mine is realized. The results show that it is effective and feasible to evaluate the rock stability with fuzzy matter-element theory，and what's more，it offers a new thought to do this.
