摘要: 长期的不合理开发与利用使得我国矿区环境问题尤为突出,对矿区进行动态监测可以有效减少矿业活动所带来的负面影响。传统的矿区环境监测多采用实地考察、逐级报告的工作方式,不但需要大量的人力、物力和时间,而且在发现问题时难以作出及时的反应,因此需要寻找一种能够满足当前矿区监测工作要求的方法。本文利用无人机获取矿区高空间分辨率影像来进行矿区开采的动态监测;获取的影像通过Agisoft PhotoScan Pro软件的SFM三维重建技术进行处理,实现了影像的快速拼接,以及高质量的数字高程模型(DEM)与数字正射影像图(DOM)的快速生成;最后利用ArcGIS软件的GIS方法得到不同时期的DEM高程变化情况及填挖方量,实现了矿区开采的动态监测。本次研究成果客观,可为矿区相关部门管理与规划矿区的开采现状提供有效的资料依据。

Abstract: Due to the unreasonable development and utilization of the mining area, the mining area environmental problems are particularly prominent. And the dynamic monitoring of the mining area can effectively reduce the negative impact of mining activities.Traditional mine environmental monitoring adopts field inspection and step-by-step reporting, which requires not only a great deal of manpower, material and time, but also a timely response to problems, so it is necessary to find a way to meet the current mine monitoring required method. In this paper, the unmanned aerial vehicle (UAV) is used to acquire the high spatial resolution image of a mining area for dynamic monitoring of mining area. The images are processed by structure from Motion of Agisoft PhotoScan Pro software, which realize the fast mosaic of images and the rapid generation of digital elevation model and digital orthophoto map. Finally, we use ArcGIS software GIS method to obtain the DEM elevation changes in different periods and the amount of fill and excavation, to achieve dynamic monitoring of mining area. The results of the study are objective,which can provide effective data for the relevant departments of the mining area to manage and plan the exploitation status of the mining area.
