Cross-border mining is an important topic of concern for surveying and mining technicians. This article takes the coal mine in Shenmu City as an example to determine the deformation aggregation area based on the average velocity map and time series analysis map obtained from InSAR monitoring of surface deformation. Using D-InSAR as a processing method to obtain the surface shape variables, surface cumulative shape variables, and maximum shape variables of subsidence map patches of SAR data in the study area, and conduct accuracy error analysis. Finally, the coal mining face and surface settlement range in the mining area are combined to accurately determine the boundary mining coal mine and export its geographical coordinates as the target area for suspected overlying boundary mining monitoring. InSAR technology can effectively monitor coal mining beyond the boundary, guide mining area production, overall planning and long-term development, and serve the sustainable development of mining areas.
