摘要
针对传统的矿山修复监测通常采用人工巡查的方式开展,难以量化评价修复成效,具有监管效率低、监管力度不够等缺点,提出采用无人机倾斜摄影测量的方式构建矿区2023年6月到2024年12月四期实景三维模型,通过不同时间点的线划图和数字高程数据量化矿区内建筑物拆除进度和回填土总量,实现了矿山修复的可视化管理。试验结果表明,通过无人机倾斜摄影测量可量化计算矿区复垦开展成效,为矿山生态环境修复监管提供可靠的技术手段。
Traditional mine restoration monitoring is usually carried out through manual inspection,which is difficult to quantify the effectiveness of restoration and has the disadvantages of low supervision efficiency and insufficient supervision.It is proposed to use unmanned aerial vehicle oblique photogrammetry to construct a three-dimensional model of the four phases of the mining area from June 2023 to December 2024.By quantifying the progress of building demolition and the total amount of backfill soil in the mining area through line drawings and digital elevation data at different time points,visual management of mine restoration is achieved.The experimental results indicate that the effectiveness of mining area reclamation can be quantitatively calculated through unmanned aerial vehicle oblique photogrammetry,providing a reliable technical means for the supervision of ecological environment restoration in mines.
