Blast Fragmentation of Rock with Discontinuities

posted in: | 0

In mining, accounting for pre-existing discontinuities in fragmentation prediction has followed pragmatic empirical e.g. blastability approaches. Efforts to improve prediction and blast design are increasingly employing dynamic crack propagation models. Here, a discontinuous computational approach based on the combine finite-discrete … Continued

Fracture Networks in Rock

posted in: | 0

Natural fractures such as joints and faults are ubiquitous in crustal rocks. These naturally occurring discontinuities often comprise complex networks and create highly disordered geological conditions. Fractures, along which rupture has caused cohesion loss and mechanical weakness in the rock, … Continued
