摘要
由于有色金属矿山普遍分布于地形复杂的山区,传统测绘方法难以满足矿区资源管理与安全评估的需求,而航空摄影测量技术凭借高效精准的优势,在矿区测绘等方面展现出广泛的应用潜力。本研究以航空摄影测量技术为核心,构建矿区三维模型并实现资源储量动态估算与安全风险监测。通过云南某铜矿案例分析,采用无人机航摄(飞行高度200m,分辨率5cm)获取时序影像,结合点云生成与形变分析技术,实现平面5cm、高程8cm精度的三维建模,监测周期缩短70%;识别出3处高危边坡(形变量>20cm),预警准确率达95%;动态更新矿石储量数据,误差率低于3%。研究表明,该技术可显著提升矿区测绘效率与决策科学性,为资源开发与环境管理提供可靠支撑。
Due to the widespread distribution of non-ferrous metal mines in mountainous areas with complex terrain,traditional surveying methods are difficult to meet the needs of resource management and safety assessment in mining areas.However,aerial photogrammetry technology,with its advantages of high efficiency and accuracy,has shown wide potential for application in mining area surveying and other aspects.This study focuses on aerial photogrammetry technology to construct a three-dimensional model of the mining area and achieve dynamic estimation of resource reserves and safety risk monitoring.Through the analysis of a copper mine case in Yunnan,unmanned aerial vehicle(UAV)aerial photography(flight altitude of 200m,resolution of 5cm)was used to obtain time-series images.Combined with point cloud generation and deformation analysis technology,three-dimensional modeling with a precision of 5cm in plane and 8cm in elevation was achieved,and the monitoring cycle was shortened by 70%;Identified 3 high-risk slopes(deformation>20cm)with a warning accuracy rate of 95%;Dynamically update ore reserve data with an error rate of less than 3%.Research has shown that this technology can significantly improve the efficiency of mining area surveying and decision-making,providing reliable support for resource development and environmental management.
