摘　　要：采用无人机倾斜摄影测量技术方法对贵州省清镇市麦格乡双麻窝铝铁矿开采面地表进行沉降监测作业,对获取的不同时期的航摄影像进行分析处理,生成DEM渲染数据成果,通过叠加分析多期DEM数据,获取DEM差值成果,直观展示不同时期开采面地表沉降变形信息;为对倾斜摄影监测成果进行精度检核,采用二等水准测量方法对倾斜摄影监测数据进行校核,验证了该技术方法在大面积矿区开采面沉降监测中的可靠性,消除了传统监测方法的弊端,大大提高了监测效率。In this paper,UAV oblique photogrammetry technology is used to monitor the surface subsidence of mining faces of Shuang-mawo aluminum and iron mine in Mag township,Qingzhen city,Guizhou province,and the acquired aerial photography images in dif-ferent periods are analyzed and processed to generate DEM rendering data results.The DEM difference results are obtained by super-position analysis of multi-period DEM data.,intuitively display the surface subsidence and deformation information of mining faces in different periods;in order to check the accuracy of the results of oblique photography monitoring,the second-class leveling method is used to check the data of oblique photography monitoring,which verifies the reliability of this technical method in monitoring the sub-sidence of mining faces in a large mining area,makes up for the shortcomings of traditional monitoring methods,and greatly improves the monitoring efficiency.
