发布时间：2019-02-18 14:58
【摘要】：为客观评价岩爆危险性,将物元理论与变权理论结合,构建了变权物元评价模型。首先,对指标数据规则化处理,解决传统物元模型自身局限性;其次,基于变权理论确定评判指标权重,避免评价过程中的主观性,同时使得被评价对象主动参与综合评判;第三,以非对称贴近度代替传统模型中的最大隶属度;最后,通过物元等级变量特征值的计算结果对样本等级进行评定,以权重及特征值对指标的敏感性确定影响评价结果的关键性指标。以甲玛矿为例,计算结果显示该矿为弱岩爆等级,且偏向于无岩爆,与现场实际情况吻合,与已有评判结果基本一致;倾向性指数、应力指数为敏感性指标,应力系数为一般敏感性指标。
[Abstract]:In order to evaluate the risk of rockburst objectively, a matter-element evaluation model was established by combining matter-element theory with variable weight theory. Firstly, regularize the index data to solve the limitation of the traditional matter-element model; secondly, determine the weight of the evaluation index based on variable weight theory, avoid subjectivity in the evaluation process, and make the evaluated object participate in the comprehensive evaluation actively. Thirdly, the maximum membership degree in the traditional model should be replaced by asymmetric closeness. Finally, the sample grade is evaluated by the calculation result of the eigenvalue of the matter-element grade variable, and the key index influencing the evaluation result is determined by the sensitivity of the weight and the eigenvalue to the index. Taking Jiama mine as an example, the calculation results show that the ore is of weak rockburst grade and is inclined to no rockburst, which is consistent with the actual situation on the spot and is basically consistent with the existing evaluation results. Tendentiousness index, stress index is sensitivity index, stress coefficient is general sensitivity index.
