中文摘要: 为研究复杂采空区群影响下的边坡稳定性特征,针对银山露天矿现状边坡与二期边坡,采用FLAC3D三维数值模拟方法,基于复杂采空区群与露天边坡形成历史的返演,计算了固定长高比的三维边坡模型在不同边界约束下的安全系数,并分析了复杂采空区群影响下边坡的整体稳定性特征以及单个采空区对边坡局部稳定性的影响,从而对露天矿开采过程中边坡岩体潜在危险区域进行了分类区划。研究成果为银山露天矿山安全生产防控提供了可靠依据。
Abstract:In order to study the stability characteristics of open-pit mine slopes under the influence of complex goaf groups, based on the real engineering status of the current slope and second stage slope of Yinshan open-pit mine and the FLAC3D three-dimensional numerical simulation software, the safety factors of the three-dimensional slope model with fixed aspect ratio and different boundary restraints were analyzed using the revers simulation method of the forming process of the goaf groups and slope. The overall stability characteristics of the slope under the influence of complex goaf groups and the local stability of the slope influenced by single goaf were analyzed. Further, the potentially dangerous areas in the future mining process of the rock mass of slope were recognized and classified. The research results can provide a reliable basis for the safety production control of Yinshan open-pit mine.
