Raises must be large enough to accommodate a 2.4 metre drill, roughly 2.7 x 2.7 metres horizontally. Primary ground support is installed with each round taken.
Raise Development: Raises must be large enough to accommodate a 2.4 metre drill, roughly 2.7 x 2.7 metres horizontally. Primary ground support is installed with each round taken.
Raise Rehabilitation: After the raise is driven to its’ entirety, secondary ground support is installed (subject to ground conditions) for the safety of the production crews.
Hangingwall Support: Where required, the stope hangingwall is supported with deformed strand resin-grouted cable bolts at a regular pattern along the length of the raise. This is quite effective as a means to minimize dilution, as the raise is centred in the stope and therefore the support is installed where it is needed most.
