At Troy Mine, a progression of pillar failures led to surface subsidence. Itasca back-analyzed this behavior, using a large-scale numerical model, to understand the level of stresses and failure mechanism leading to the collapse of some pillars. Forward predictions on pillar stability in another nearby deposit, in a similar geomechanical setting, were also done.
The 56th US Rock Mechanics / Geomechanics Symposium covers all aspects of rock mechanics, geomechanics, and rock engineering.
Mr. Wang is a senior geomechanics engineer with experience in mining engineering and geotechnical engineering. His research involves numerical modeling and simulation, and has involved projects related to sheet-pile walls with retained slope, mine-void detection using geophysical methods and stability of underground mines. He is the Software Product Manager for FLAC.
