The studied mining area
is located north of Stockholm, 1,200 m deep, in one of the deposits of Garpenberg polymetallic mine.
A multidisciplinary approach has been implemented: it integrates visual observation of the deep underground environment, predictive and comparative 3D geomechanical digital modeling, high-resolution microseismic and geotechnical monitoring, as well as production data follow-up.
The objective is to better understand the conditions and dynamics of small-and large-scale rock deformation and fracturing as well as the aseismic mechanisms and their impacts, in response to exploitation. Specific in situ experiments are planned, the analysis of microseismic data will include the application of template matching * methods, taking advantage of the e.cenaris
monitoring infrastructure.A doctoral project
has also started in March 2020, in collaboration with the GeoRessources laboratory (University of Lorraine) and the Institut de Physique du Globe de Paris, and with the support of the Grand-Est region. It follows Francesca De Santis' doctoral thesis
, defended in February 2019.
