本文对地理国情监测的具体案例,某尾矿库监测实施过程中主要技术进行了详细的描述。通过静态GPS测量方法完成了尾矿库控制测量工作,按国家统一坐标系解算了尾矿库基础控制点、监测点等坝体要素的三维坐标,并和尾矿库监测点的原始独立三维坐标进行对照、比较,根据不同高程基准坝体高差变化、尾矿库设计高度等坝体数据进行综合分析,绘制高程标注图。研究结果为尾矿库安全运行提供了准确、可靠的监测数据及相关合理建议。
In this paper, the specific case of geographic condition monitoring, the main technology in the monitoring of a certain tailings dam are described in detail. The measurement of tailings dam was completed by static GPS measurement method. The three-dimensional coordinates of tailings dam base control points, monitoring points and other dam elements were solved according to the unified national coordinate system, and the results were compared with the original independent three-dimensional Coordinates, comparison, according to different elevation datum dam body height difference, tailings dam design height of the dam body such as a comprehensive analysis of the data to draw elevation annotation diagram. The results provide accurate and reliable monitoring data and relevant reasonable suggestions for the safe operation of tailings ponds.
