摘要
该文以四川省会东县某公司小沟头尾矿库建设规划为研究案例,探究无人机摄影测量技术在该领域的适用性。与传统GPS-RTK测量数据相比,无人机摄影测量的水平和高程中误差为0.311m、0.304m,满足矿山尾矿库建设规划运用需求。通过分析,无人机摄影测量具备以下特性:(1)外业工作时间低于传统测量数倍,工作效率具备明显优势;(2)高精度DOM能更方便地辅助尾矿库周边区域地物识别与标注;(3)地表高程数据受地物直接影响,能真实反映地表起伏;(4)三维可视性强,可辅助实现尾矿库3D规划展示和堆积核算。实验表明,无人机摄影测量技术能有效辅助尾矿库建设规划以及安全风险评价,可为有关管理部门实施矿山合理建设和生产提供技术支撑和执法依据,具备良好市场运用前景。
This paper takes a company in Huidong county, Sichuan province as a case study, to explore the applicability of UAV photogrammetry technology in this field. Compared with the traditional GPS-RTK measurement data, the error of UAV photogrammetry level and height is 0. 311 m and 0. 304 m, which meet the needs of mine railings reservoir construction planning and application. Through the analy- sis, the UAV photogrammetry has the following characteristics： the field work time is several times low er than the traditional measurement, and the working efficiency has obvious advantages; high precision DOM can help to identify and mark the surrounding area of tailings reservoir more conveniently; surface elevation data is direc＇tly affected by the fea＇tures, can truly reflect the surface fluctuation; 3D visibility is strong, can assist to realize 3D planning display and accumulation accounting of tailings reservoir. The experimental results show that the UAV photogrammetry technology can effectively assist the construction planning and safety risk assessment of the tailings pond, which can provide technical support and law enforcement basis for the management department of the mine construction and production, and has good market application prospect.
