摘要
【目的】探讨无人机与GIS技术在尾矿库闭库阶段的地质灾害探测与防治中的协同应用,为尾矿库闭库工程的安全实施提供数据支撑,助推绿色矿山建设。【方法】以甘肃省某尾矿库为研究对象,基于无人机倾斜摄影测量技术和GIS空间分析技术进行研究。【结果】获取了尾矿库的DOM和DSM等基础地理数据,探测识别了尾矿库周围存在的7处不稳定斜坡。【结论】结合基础地理数据和现场环境条件提出了将削坡缷荷、支护加固和坡面修复等3种方式综合应用的地质灾害防治措施。
[Purposes]This study explores the synergistic application of UAV and GIS technologies in the detection and prevention of geological hazards during the closure phase of tailings ponds,aiming to pro⁃vide data support for the safe implementation of tailings pond closure projects and to promote the devel⁃opment of green mines.[Methods]A tailings pond in Gansu Province was selected as the study area.The research was conducted based on UAV oblique photogrammetry and GIS spatial analysis techniques.[Findings]Basic geospatial data such as DOM and DSM of the tailings pond were obtained,and seven unstable slopes around the pond were identified.[Conclusions]Based on the geospatial data and field environmental conditions,a comprehensive geological hazard mitigation strategy was proposed,involving slope cutting and unloading,support reinforcement,and slope surface restoration.
