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.
Its experienced staff of hydrogeologists, geologists, geochemists, and engineers enables Itasca to address virtually all aspects of mining hydrogeology, including dewatering, depressurization, water quality, water balances, mine-water disposal, water supply, water management, and field investigations. With offices situated around the world, Itasca possesses first-hand knowledge of the particular mining challenges in each local region. Itasca pool of expertise covers the gamut of mine operations, from hard to soft rock mining in both open pits and underground mines. Itasca hydrogeologists and engineers have taught mining hydrogeology short courses at annual meetings of the Society for Mining Metallurgy and Exploration (SME) and for mining clients around the world.
One of Itasca’s strengths is the ability to effectively design and optimize mine dewatering and depressurization systems. The company designs and supervises the installation of dewatering wells, sub-horizontal drain holes, drainage galleries, and seepage-collection systems for surface and underground mines located around the world.
In additional to the operational hydrogeologic aspect, Itasca also performs work related to the environmental and permitting aspects of mining projects. Experience in these areas ranges from the baseline characterization of hydrogeologic conditions and mined materials (waste rock, tailings, and ore) to the technical evaluation of potential or observed water-resource impacts for the National Environmental Policy Act (NEPA) and/or State permits, such as drawdown of the groundwater table, subsidence, and water-quality impacts.
Itasca has developed a sophisticated, three-dimensional, finite-element groundwater flow model code called MINEDW™ specifically for the evaluation of complex mining water-related issues. MINEDW is currently being used worldwide at many large-scale open-pit and underground mines. Depending on a client’s requirements, the widely-known MODFLOW and FEFLOW numerical codes are also used.
The core services offered include the following.
