Dr. Aglawe is a mining engineer with experience in rock mechanics (hard and soft rock) and in application of advanced numerical modeling for mining and civil projects. He has been involved in the development of models for tunnels, caverns and dams in hydroelectric projects.
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.
Caving is applied to increasingly deep, large, strong, and heterogeneous ore bodies. This increases the risk of stranded reserves in overhangs, potential for cave stall and air-blast, infrastructure rehabilitation or loss, and large-scale caving-induced subsidence. Geomechanical analyses are therefore critical to understand and predict:
Itasca simulates mine caveability and subsidence using the continuum program FLAC3D and the discrete element programs 3DEC and PFC to predict the progressive failure and fragmentation of the rock mass from an intact/jointed to a caved material. Both FLAC3D and 3DEC can utilize Itasca’s CaveHoek and Imass material models, whereas both 3DEC and PFC can utilize bonded or free-flowing blocks/particles.
Coupled with Itasca’s deterministic, physics-based code REBOP or the statistical, cellular automata code CAVESIM, the collapse, bulking, and movement of caved rock can be better incorporated. The coupled method captures many important aspects of caveability affecting cave design, such as hang-up formation, material recovery, timing of surface breakthrough or interaction with other lifts, crater development, and surface subsidence.
