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. Lorig has more than 35 years of experience in engineering projects requiring specialized geomechanics consulting. His area of expertise is in the application of numerical models to provide solutions to stability, support and dynamics problems in civil and mining engineering.
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
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.
