For this purpose, an area under production of the metal mine of Garpenberg (Sweden) was instrumented with a geophysical and geotechnical monitoring network. In situ monitoring data were analyzed and interpreted considering mining operations and the local geological setting. In addition, a 3D elasto-plastic numerical model was built to better understand the interactions between quasi-static stress changes due to mining and the generation of the induced seismicity. Results of this multiparameter approach show a complex rock mass response. We observed two main types of seismic behaviors: one local and temporally short, directly induced by production, the other long-lasting over time and remote from excavations being mainly controlled by geological heterogeneities. In addition to seismicity, we also observed creep-like phenomena induced by mining. In turn, these time-dependent strains appear to be a third mechanism driving seismicity. All these findings underline the importance of considering both seismic and aseismic deformations when one wants to characterize the rock mass response to mining. This significantly enhances our understanding of the phenomena involved, as well as their interactions, for an improved hazard assessment in deep mining operations. date: 2020-05 publication: International Journal of Rock Mechanics and Mining Sciences volume: 129 number: 104273 publisher: ScienceDirect id_number: 10.1016/j.ijrmms.2020.10427 issn: 1365-1609 official_url: https://www.sciencedirect.com/science/article/pii/S1365160919311888?via%3Dihub access_IS-EPOS: limited owner: Publisher citation: De Santis, Francesca and Renaud, Vincent and Gunzburger, Yann and Kinscher, Jannes and Bernard, Pascal and Contrucci, Isabelle (2020) In situ monitoring and 3D geomechanical numerical modelling to evaluate seismic and aseismic rock deformation in response to deep mining.
