Open pit mining often result in high rock slopes, sometimes combined with difficult rock conditions. This is further augmented by large blasting rounds resulting in high vibrations. Reinforcement of pit slope walls is also difficult and many times associated with high costs and loss of production. Bench slope stability is vital for a safe working place for all personnel in the mine as well as for avoiding production loss. Itasca Consultants AB is providing technical, on-site rock mechanics expertise to several open pit mines in northern Sweden.
The 56th US Rock Mechanics / Geomechanics Symposium covers all aspects of rock mechanics, geomechanics, and rock engineering.
Miguel Fuenzalida (M.A.Sc., B.Eng.) is a senior geomechanics engineer at Itasca Consulting Group, a consulting and software firm across the mining, civil engineering, and energy industries. He holds a Bachelor’s degree and a Master of Science in Mining Engineering from the University of Chile. He has received the “Juan Bruggen” Best Graduate of the Class of 2010 Mining Engineering Award by the Mining Engineering Institute of Chile (IIMCh). Based in Minneapolis, USA, Miguel provides consulting services to underground mining by applying numerical modeling to sequencing, stability, ground support, and mining-induced seismicity. Miguel has extensive experience in sublevel, block and panel caving projects—from concept to feasibility level—and cave mines in North America, South America, Africa, Eastern Europe, Southeast Asia, and Australia where he has specialized in undercut and extraction level design, draw scheduling, forecasting of caveability, fragmentation, recovery, infrastructure stability, and surface subsidence. He has participated in several mining and rock mechanics conferences and has been part of international collaborative research consortiums such as Mass Mining Technology (MMT) and Caving2040, focused on critical reviews of conventional caving design approaches, collation of common caving practices, and advancing the understanding of caving fundamentals. He is currently a member of the American Rock Mechanics Association (ARMA) and the Society of Mining Engineering (SME).
