Dans le cadre des séminaires de l'équipe GOR de GeoRessources, Dalija NAMJESNIK doctorante en troisième année, encadrée par Yann Gunzburger (UL) et Jannes Kinscher (Ineris), fera une présentation de 30 min le jeudi 12 décembre 2019 à 12h dans la salle R020 à l'Ecole des Mines de Nancy. Sa présentation est intitulée « Origin of seismicity related to a flooded abandoned coal mining district at Gardanne, Provence, France ». Vous trouverez ci-dessous un résumé de ce projet.
Gardanne mine. Post mining seismicity problem
In flooded, abandoned coal mine at Gardanne in Provence region, local microseismic monitoring network has been detecting significant periodic seismic activity that seems to originate from an interaction between rocks and fluids. To reliably assess local seismic hazard, detailed understanding of the triggering mechanisms of observed seismicity is crucial, as well as knowing whether it indicates a fracture or faults system near a critical state of rupture, or simply episodes of small transient creep. Thesis project therefore focuses of seismic data analysis and further, combining these results with hydrogeological analysis and geomechanical modelling.
