摘要
露天矿山高陡边坡的安全稳定具有重要意义。蕲春县石鼓冲绿色建材基地项目建设的特大型绿色砂石矿山露天开采后将形成高度超过450 m,坡度达60°的高陡边坡。本文对矿山高陡边坡进行工程地质分区,利用GeoStudio进行多工况的边坡渗流分析和稳定性评价,基于稳定性评价结果开展矿区边坡的分期监测方案研究,构建了多要素分期监测网络。提出的矿区高陡边坡稳定性分区评价方法和分期监测方案有助于有效管控边坡地质灾害风险。
The safety and stability of high and steep slopes in open-pit mines are of great significance for the stable operation of mining enterprises.After the open-pit mining of the super large green sand and gravel mine in Shiguchong Green Building Materials Base project in Qichun County,a high and steep slope with a height of over 450 m and a slope of 60°will be formed.Engineering geological zoning was carried out on high and steep slopes in mines,and GeoStudio was used for multi condition slope seepage analysis and stability evaluation.Based on the stability evaluation results,a staged monitoring plan for mining slopes was studied,and a multi-element staged monitoring network was constructed.The proposed zoning evaluation method and staged monitoring plan for the stability of high and steep slopes in mining areas are helpful for mining enterprises to effectively control the risk of slope geological disasters.
