Abstract
Abstract. Monitoring of mining areas and associanted dam stability, has become increasingly important as the awareness of safety and environmental protection is rising. An appropriate monitoring scheme is necessitated to legally activate, reactivate, or terminate mining operations. The project Integrated Mining Impact Monitoring (i2Mon) aims to identify and analyze mining-induced impact, in particular its ground deformation. The monitoring system comprises terrestrial measurement and remote sensing: levelling, GPS, LiDAR scanning, UAV survey, and SAR interferometry. For interpretation and prediction, modelling will be used to simulate local displacements by different factors. The final goal is to launch an interactive GIS-based platform as an early warning and decision making system for mining industry. Currently, the project is proceeding from a preparatory phase. This paper focuses on spaceborne SAR interferometry, whereby we can cost-effectively monitor ground movement at millimeter level over a large area. We introduce the prototype of our InSAR monitoring system. The test result from Sentinel-1 images shows the surface movement during 2018 at a deactivating open-pit coal mine in Germany. We discuss the current status, ongoing works, planned test sites in Poland, and how we integrate data from different sensors and approaches.

Summary
The mining industry accounts for an important component of their economy. Open-pit and underground mining causes surface deformation like ground subsidence Monitoring this mining impact is increasingly important for the safety of human lives and properties. Remote sensing based on spaceborne data offers an efficient and cost-effective alternative This technique aims at frequent surveillance over large areas and provides comparable complements to in-situ measurement data. Distributed scatterer interferometry (DSI) (Berardino et al, 2002; Ferretti et al, 2011; Lanari et al, 2007) approaches are used and adapted These two approaches estimate surface movement across a broad area at millimeter accuracy. The active sensors are weather independent and have a day-and-night vision ability This advantage makes SAR images free of cloud occlusion and always available for use.
