摘要
露天矿山边坡安全是影响整个矿山安全生产的关键因素,为了解决顺层边坡治理问题,文中以某金矿为例,根据前期地质探勘和最终圈定境界揭露情况,将边坡划分为边坡整体性较差,岩体内部节理裂隙较发育型;边坡整体性较好,岩体内部节理裂隙较发育型;边坡整体性好,岩体内部节理裂隙不发育型三种类型,提出了锚(索)杆主动支护+锚(索)杆、网片、喷浆耦合分区支护技术及治理方案,提高了边坡稳定性,消除了安全隐患,提供了安全工作空间.
Abstract
In order to solve the problem of slope treatment along the layer,this paper takes a gold mine as an example,according to the results of early geological exploration and the final delineation realm disclosure,the slope is divided into slope integrity is poor,the internal joint frac-tures of the rock mass are more developed,the integrity of the slope is better,the internal joint fractures of the rock mass are more developed,the integrity of the slope is good,and the internal joint fractures of the rock mass are not developed.The spray coupling zoning support technol-ogy and treatment scheme improve the stability of the slope,eliminate the potential safety hazards,and provide a safe working space.
