无人机摄影测量在矿山土石方采剥量计算中的应用

The Application of UAV Photogrammetry in the Calculation of the Amount of Earth and Stone Excavation

矿山开采过程中,确定土石方采剥量对矿山的生产成本监控具有重要的意义。但传统的测量手段消耗大量的人力、物力和财力,且在区域环境恶劣的条件下还给测量人员带来安全隐患。无人机为矿山土石方量的计算提供了新思路,其不受矿山地形的影响,可在短时间内获取相应区域的土石采剥量,快捷方便,可行性高,大大减少了外业工作量,且内业自动化程度高。本文通过获取研究区域两期无人机影像数据,利用数据成果在Civil 3D中计算两期土石方量,通过相应的检查点检验其精度,成果达到相应国家规范的土石方计算精度要求,为类似工程案例提供思路与借鉴。

In the process of mining,it is of great significance to determine the amount of earthwork for the production cost monitoring of the mine.However,the traditional measurement method consumes a lot of human,material and financial resources,and under the condition of bad regional environment,it also brings security risks to the measurement personnel.UAV provides a new idea for the calculation of the earth and stone volume of the mine.It is not affected by the mine topography,and can obtain the earth and stone mining and stripping volume of the corresponding area in a short time,which is fast,convenient,highly feasible,greatly reducing the workload of the field work,and the automation degree of the field work is high.In this paper,the UAV image data of two phases in the research area are obtained,the earthwork volume of two phases is calculated in civil 3D by using the data results,and the accuracy is verified by the corresponding checkpoints,and the results meet the accuracy requirements of the corresponding national specifications for earthwork calculation,providing ideas and references for similar engineering cases.
