锚杆连梁技术在高陡岩质边坡支护与生态修复中的应用——以安徽省萧县露采边坡支护与复绿工程为例

Application of the technique of anchor bolts and tie beams in the support construction for steep rock slopes and their ecological restoration: A case study of the support and reforestation project for the slopes of an open pit in Xiao County, Anhui Provinc

矿山露天开采常常形成高陡岩质边坡,受岩体结构面的组合影响,局部地段容易形成危岩体,影响坡体稳定性,而对于高陡边坡难以实施常规生态修复措施,在场地条件受到限制时又不能采用削坡方式放缓坡度。为解决这一技术难题,笔者在萧县牛头山矿山地质环境治理高陡边坡支护和生态修复工程中采取了“锚杆连梁技术”辅助复绿,在对危岩治理的同时,也为喷播复绿奠定了基础,有效地解决了这类崩滑地质灾害和生态修复问题,取得了较好的效果。该方法可为同类工程提供借鉴。

High and steep rock slopes are often formed in open-pit mining. Due to the combined effect of rock mass structural surfaces, dangerous rock masses are easy to form in some parts, which affects the stability of slope bodies. It is difficult to implement conventional ecological restoration measures for high and steep slopes. When the site conditions are limited, slope cutting cannot be used to reduce the slope grade. In order to solve the technical problem, we applied anchor bolts and tie beams in the high and steep slope support construction for facilitating ecological restoration as we performed mine geo-environment treatment in Niutoushan, Xiao County. The technique has been proved effective in treating the slopes to avoid collapses and landslides, and laying a basis for ecological restoration, which can be used for reference.
