A methodology to select valid results from Lab tests to estimate properties of intact rock with microdefects

Mr. Russo has 25 years of experience in the mining industry. He has worked in porphyry copper deposits such as El Teniente and Chuquicamata underground project acquiring a strong experience in geological, structural and geotechnical mapping for underground mining, geological and geotechnical logging of drill holes and identification and characterization of geotechnical domains and lithologic model update. He has a strong experience in geotechnical characterization of rock mass according to Laubscher, Barton, Bieniawsky and GSI of Marinos & Hoek classification systems, geomechanical laboratory tests analysis, definition of the caving sequence and caving orientation. Definition of ground support through empirical methods such as Barton´s Q and validation through numerical models such as Phase2. He has worked on various open pit projects analyzing slope stability. He has worked on an environmental project acquiring experience in rock mass grouting using the GIN method. For his degree thesis he worked on the genetic model of several ore bodies in SW Sardinia (Italy) (SEDEX type deposits). His doctoral work involved the tectonic - sedimentary evolution of a carbonate platform of the Lower and Middle Cambrian in the NW of Spain and the genetic model of two mineralized levels at the base and top of the formation (SEDEX type deposits).
