摘　　要：多采场开采下,重复应力扰动易产生衍生灾害.针对缺少评价协同开采效用和衍生灾害防控效用指标的问题,通过综合协同开采效用因子与衍生灾害防控效用因子,提出了协同开采指数的构建方法.以某金属矿山为工程背景,建立了不同采场参数的数值模型,计算了不同采场和矿柱尺寸协同开采指数,揭示了多采场开采过程中应力扰动影响规律及其衍生灾害效应.基于现场监测结果,验证了协同开采指数对多采场开采协同开采效用和衍生灾害防控效用评价的有效性,研究成果可为采场最优结构参数的确定提供参考.Repeated stress disturbance tends to produce derivative disasters in multi-stope mining.In view of the lack of evaluation indicators of the effectiveness of cooperative mining and derived disaster prevention and control,the construction method of cooperative mining index is proposed by integrating the effectiveness factors of cooperative mining and derived disaster prevention and control.Taking a metal mine as the engineering background,the numerical model of different stope parameters is established,the cooperative mining index of different stope and pillar size is calculated,and the influence law of stress disturbance and its derivative disaster effect in multi-stope mining process are revealed.Based on the field monitoring results,the effectiveness of cooperative mining index in evaluating the effectiveness of multi-stope cooperative mining and derivative disaster prevention and control is verified,and the research results can provide reference for determining the optimal stope structural parameters.
