This training is an introduction to continuous modeling with FLAC2D and FLAC3D. At the end of the course, participants will master the graphical interface, documentation and the main modeling steps. Concepts are illustrated using a tunnel excavation example, from building the model geometry to results analysis. This introductory course provides the foundation for more advanced use of the software, which can be covered in more specific training modules.
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
