... and then related to in-situ conditions. The rock mass consists of finite-thickness horizontal layers separated by zero-thickness parting planes; also, a finite-thickness dyke may be defined ahead of the stope face. The generic stope model consists of a rectangular FLAC model within which may be embedded...

.... Preliminary studies indicated that the initial jump in stope closure after blasting is correlated with the stope face stress. 1 INTRODUCTION The design of deep level mine layout configurations and the implementation of effective strata control strategies is often reliant on direct experience of mining...

... with the consequence that the rock inevitably fractures. Figure 1 shows the fractured rock at a stope face. Figure 1. Photograph showing fractured rock at a stope face. All stoping takes place within this environment of fractured rock, therefore it is important if mining methods are to be improved that the generation...
