中文摘要: 岩爆是矿山生产中棘手的地质灾害,严重威胁人员与设备的安全。为了对岩爆进行合理预测,选取应力系数σθ/σc、脆性系数σc/σt和弹性能量指数Wet作为分级评判指标,主客观组合赋权确定指标间的权重,主观赋权方法为专家打分法,客观赋权方法为熵权法,采用乘法合成法进行组合赋权。通过组合赋权调整权重确定的主观性,建立组合赋权的可拓综合评价岩爆预测模型。将建好的模型应用于工程实例中,预测结果与实际情况一致,是一种可以应用于工程的模型。
Abstract:Rockburst is a difficult geological disaster in mine production, which seriously threatens the safety of personnel and equipment. To reasonably predict rockburst, the stress coefficient σθ/σc brittleness coefficient σc/σt, and the elastic energy index of Wet are selected as grading evaluation indexes. The weights of the indexes are determined by the combination of subjective and objective weights. The subjective weighting method is an expert scoring method, the objective weighting method is an entropy weighting method, the combination weighting method is used to adjust the subjectivity of weight determination through combination weighting, and the extension is comprehensive evaluation rockburst prediction model of combination weighting is established. The established model is applied to the project, and the predicted result is consistent with the actual situation, which is a model that can be applied to the project.
