    摘要:

    本文以广西区内两处露天矿区作为研究区域进行矿产资源储量监测,探讨低空无人机倾斜摄影测量技术在矿产储量监测方面的应用,为矿产资源有效地保护与开发利用提供科学的数据支撑。基于ArcGIS和Context Capture两款软件,详细阐述了利用ArcGIS提取高程点进行DTM法矿区动用储量计算和基于Context Capture软件进行矿产储量计算的两种方法,并运用新兴技术与传统成熟技术结合的方法,实现对露天矿区的储量监测,最后在检验产品精度符合规范要求的情况下,完成两种方法的精度比较。实验结果表明:1)采用两种不同方法对两处矿区进行矿产资源储量监测,得出其误差百分比分别6.17%、0.05%,相对误差均满足规范要求;2)无人机倾斜摄影技术可用于矿产资源储量的动态监测,该技术在简化作业流程的基础上,可以低成本、快速、动态的实现矿区动用储量的监测,为有关部门的管理和矿产资源的开发利用提供科学的数据支撑。

    Abstract:

    In this paper, two open-pit mining areas in Guangxi were taken as the study area to monitor the reserves of mineral resources. The application of low altitude UAV tilt photogrammetry technology in mineral reserves monitoring was discussed for providing scientific data support for the effective protection, development and utilization of mineral resources. Based on ArcGIS and Context Capture, the two methods of extracting elevation points by ArcGIS for DTM mining area production reserve calculation and mineral reserve calculation based on context capture software were described in detail, and then the combination of emerging technology and traditional mature technology were used to realize the reserve monitoring of open-pit mining area. Finally, the accuracy comparison of the two methods was completed under the condition that the product accuracy met the specification requirements. The experimental results show that: 1) two different methods were used to monitor the mineral resources reserves in two mining areas, and the error percentages are 6.17% and 0.05% respectively, and the relative errors satisfy the specification requirements; 2) UAV tilt photography technology can be used for dynamic monitoring of mineral resources reserves. On the basis of simplifying the operation process, this technology can realize low-cost, fast and dynamic monitoring of mining reserves, and provide scientific data support for the management of relevant departments and the development and utilization of mineral resources.
