An Extended Conceptual Model of Caving Mechanics

Daniel Jacques Cumming-Potvin

Research output: ThesisDoctoral Thesis

Abstract

The Duplancic conceptual caving model is the industry accepted model and the framework within which most results from numerical modelling and cave monitoring are interpreted. The Duplancic conceptual model implies that the damage ahead of the cave back decreases continuously with increasing distance from the cave surface. Evidence from a variety of sources indicates that this may not always be the case and that a discontinuous damage profile may be present. This thesis re­examines the Duplancic model and creates an extended conceptual model of caving. This extended model captures the
caving mechanism of discontinuous damage through parallel fracture banding.
