摘要
边坡稳定性是露天矿区的重要安全问题,地下水严重影响着露天矿边坡的稳定。从研究区边坡地下水渗漏这一现实问题出发,提出对可能的渗漏源头区开展高密度电法工作。通过对实际数据处理和反演,并利用三维可视化与切片提取技术对电阻率异常体进行提取,最终确定了两处地下水渗漏通道。经与现场边坡渗漏情况对比分析,高密度电法应用于边坡地下水渗漏探测准确可靠,可为露天矿边坡防治提供可靠依据。
Slope stability is an important safety problem in open-pit mine.Groundwater seriously affects the stability of open-pit mine slope.Based on the practical problem of groundwater leakage in the slope of the study area,this paper proposes to carry out high density electrical method for the possible seepage source.Through the actual data processing and inversion,and the application of 3D visualization and slice extraction technology to extract the electrical anomalies,two groundwater leakage channels were finally determined.The high density electrical method is accurate and reliable on detecting groundwater leakage,the result can provide reliable references to landslide risk prevention and treatment for open-pit mine slope.
