This work addresses a methodology based on the Interferometric Synthetic Aperture Radar (InSAR) to analyse and monitor ground motion phenomena induced by underground mining activities, in the Legnica-Glogow Copper District, south-western Poland.Two stacks of ascending and descending Sentinel-1 Synthetic Aperture Radar 3701129802670 (SAR) images are processed with a small baseline multitemporal approach.A simple method to select interferograms with high coherence and eliminated images with low redundancy is implemented to optimize the interferogram netwrork.

The estimated displacement maps and time series show the effect of rectangular barn quilt patterns both linear and impulsive ground motion and are validated against Global Navigation Satellite System (GNSS) measurements.
