Hydrogeological Hazards in Open Pit Coal Mines–Investigating Triggering Mechanisms by Validating the European Ground Motion Service Product with Ground Truth Data

This research focuses on the investigation of hydrogeological hazards in open pit coal mines. The study area is Amyntaio sub-basin area, located West Macedonia prefecture, Greece. A major part SE this occupied by mine. In recent decades, basin’s aquifer has been overexploited both dewatering wells mine and irrigation wells, triggering extensive land subsidence an that extends 3 km around Additionally, one biggest mining landslides worldwide occurred South-West slopes 10 June 2017. current investigates phenomenon landslide, highlighting influence interaction their causal factors which were strongly affected groundwater management. To estimate ground surface movement, Earth Observation data from European Ground Motion Service, Copernicus Union′s observation program, used for period 1 January 2016–31 December 2020. geologic, geotechnical hydrogeologic coming truth survey have incorporated with data, opposing mechanisms interacting geohazards.
