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. Sylvain provides editorial and authorial input to Itasca software documentation.
