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.
