George Fisher doubles down on raiseboring
Contractors Pybar and RUC are carrying out two simultaneous raiseboring projects at Glencore's George Fisher mine to boost ventilation underground and sustain the southern blocks of its L72 operations.
The works will see the addition of a new fresh air intake and return air shaft, both stretching 750m from the surface to underground and each with a diameter of 5m.
Senior project engineer Robert Harrington said running two raiseboring contractors meant operation had access to more specialised equipment.
"This will save about 18-months on the project schedule and provides the best overall return on investment,” he said.
