Mr Lachenicht has 25 years’ experience in mining geomechanics ranging from consulting, research projects, studies to mine operational experience. Over the course of his experience, positions held include manager, senior geotechnical engineer, geotechnical superintendent and principal geotechnical engineer roles with associated levels of responsibility.
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 Fifth International Itasca Symposium will be held at the University of Vienna (Austria). The Symposium will features the application of Itasca software for solving engineering and scientific challenges in geomechanics, hydrogeology, microseismicity, and more.
David is a principal geotechnical engineer with more than 20 years of operations and consulting experience in the mining and civil industries. Since joining Itasca in 2007, David has performed numerical back analyses and forward analyses for numerous open pit and underground mining operations around the world using Itasca software. David has also performed numerical analyses for several surface and underground civil infrastructure projects.
It has become common practice to create a three-dimensional (3-D) geomechanical model for the analysis of rock stability. One of the key inputs for a geomechanical model is the 3-D pore-pressure distribution. For complicated geologic settings under excavation, such as open pit walls and underground mine workings, pore pressures generally do not follow hydrostatic distributions with depth; therefore, a 3-D groundwater flow model is required to simulate pore-pressure distributions. MINEDW is a groundwater flow model code that was specifically developed to simulate the complicated hydrogeologic conditions related to mining. It is capable of simulating the excavation of open pits and underground workings, and the changing hydraulic conductivity of the displaced rocks surrounding the excavated area. This paper describes the features of MINEDW and how MINEDW can export 3-D pore-pressure distributions to be readily useable in FLAC3D and 3DEC models.
