Abstract:
The Cannington mine embarked on several significant ground support rehabilitation projects during 2006 in
response to safety and business risk concerns arising from falls of ground, decreasing reliability of older
installed ground support, and potential time delays of main accesses to the production ore blocks from
ground instability. This instability was caused by regional structurally controlled ground movements,
triggered by excavation of the stopes within the Southern Zone. This combined with the lack of sufficient
ground reinforcement capacity (from historically installed ground support), and absences of surface
retention and ravelling prevention between the rocks bolts due to the lack of surface support such as mesh or
fibre reinforced shotcrete (fibrecrete) that was not installed during the early Cannington project
development.
