... rock, especially in the hangingwall, can be kept in place to reduce the amount of damage and production delays resulting from rockfalls and rock- bursts. The primary function, therefore, of an imme- diate stope face support system is to maintain'the in- tegrity of the fractured hangingwall beam...

... are influenced by many factors, however, given a set of conditions the local stability of the usually intensely fractured hangingwall is largely dependent on the detailed mechanisms of interaction between supports and the blocky rock at the skin of the excavation. Detailed modelling of this region may provide...

... to simulate the observed underground failure and to identify the fundamental failure mechanisms. The influence of variations of support types and support spacing on hangingwall stability was established. The results have provided insights into the mechanisms which are taking place and which influence rockmass...

... ABSTRACT ABSTRACT Reef and concrete stabilising pillars are modelled in the two dimensional plane strain code FLAC. The rock mechanics criteria used for comparison are hangingwall stability, pillar stress distribution and stope closure profile, as well as the punching effect of the pillar...
