The Influence of Blast Fragmentation on Loadability in Sublevel Caving
By Daniel Johansson, Markus Danielsson, Håkan Schunnesson
In sublevel caving, blasted material flows gravitationally into the drawpoint from above in a periodical manner. This type of flow behavior entails muck pile conditions that are variable along the cou
