stability of tailing storage facilities, laboratory tests, numerical analysis
1.3 Mine closure and reclamation
We would like to participate in a larger consortium where we can provide stability analysis regarding tailings storage facilities (TSF) such as tailing dams or piles of filtered tailings, as well as the evaluation of mine closure actions in safe conditions. We have a good geotechnical laboratory experienced in analyzing stress-strain, consolidation and resistance parameters, also at the light of critical state soil mechanics, of these evolving materials. These parameters can be used in advanced deformation numerical analysis with models capable of coping with the high deformations existing in liquefaction phenomena.
We are also capable of testing the addition of flocculants, superabsorbing polymers or additives that may reduce tailings water content, or add strength preventing their liquefaction potential.
Excellence. Innovation. Entrepreneurship. Qualities that make FEUP a faculty of repute in Portugal and abroad. Its mission is to train world-class engineers and our effort is on research and development of excellence.
FEUP works closely with several respected institutions such as the European Space Agency (ESA), IBM, Microsoft and the European Organization for Nuclear Research (CERN). It also teams up with research universities such as the Massachusetts Institute of Technology (MIT), the University of Texas at Austin (UTA) and the Carnegie Mellon University (CMU).Supported on its high quality R&D, which is produced as a result of the excellence of its various research units and its strong international partnerships, FEUP is an institution that seeks to ensure that students are able to conceive, develop, implement and operate complex systems in order to generate added value in an environment of social and professional sustainability, based on ethical principles.
Our research center, CONSTRUCT – Institute for research and development in construction, comprises 6 very well equipped laboratories in the civil engineering area with expertise in geotechnics, geosynthetics, concrete technology and structural engineering, seismic engineering as well as vibrations and structural monitoring.
In particular, the Geotechnical Laboratory includes the following main equipments: an Automated Dynamic-Cyclic Triaxial System with continuous Seismic Wave Velocities's Monitoring; an automated True Cubic Triaxial System and Double Cell Triaxial System with Suction Control and measurement, assembled with Piezotransducers for S and P waves velocities measurements; an automated Stress-Paths Triaxial System, with internal monitoring of forces, displacements , Vs and Vp (Bender/Extender Elements) and mid-height pore/suction pressures.
These laboratory facilities have allowed several PhD thesis and a significant number of publications in international journals (JRC) expression the high experience of the CONSTRUCT-GEO group for these studies.
