Dr. Detournay has experience in the development of numerical models for application to coupled fluid-thermo-mechanical problems. She is a principal developer for the groundwater-flow and thermal logic in FLAC3D, and has been involved in the development of several of the constitutive models available with Itasca continuum codes.
FLAC3D TMis a numerical modeling code for advanced geotechnical analysis of soil, rock, and structural support in three dimensions. FLAC3D is used in analysis, testing, and design by geotechnical, civil, and mining engineers.
This FLAC3D V7.0 training course accommodates new and experienced users. It will be based on examples that attendees will develop and run by themselves to better grasp the mechanics of using FLAC3D V7.0, the key underlying calculation principles and the spectrum of available features. Attendees are encouraged to bring one of their specific cases that may be discussed.
The upcoming 70th annual Highway Geology Symposium will be held in Portland, Oregon, October 21st through October 24th, 2019.
Dr. Fairhurst, BSME, DEA, PhD, obtained his BSME degree in Mechanical Engineering from the University of Minnesota, Institute of Technology, Minneapolis, Minnesota (USA) in 1983 and obtained his DEA and PhD in Mining Technologies from the Ecole Nationale Supérieure des Mines de Paris, in Fontainebleau, France in 1984 and 1987, respectively.
Itasca Denver, Inc., (Itasca) in conjunction with Newmont Mining Corporation (NMC) developed a numerical model to estimate gold (Au) production from NMC’s heap-leach operations. A current practice of prediction of cyanide gold (AuCN) recovery at NMC is based on spreadsheet models (Excel®) that are unique for each operation. NMC has found that the tool is very useful for short- and long-term predictions of Au production; however, the methodology is limited for quantitatively assessing mechanisms for improvement and optimization of Au recovery. Hydrodynamic modeling is an alternative to the existing practice of prediction, and it is a complimentary addition to the existing predictive techniques
