AVKO Mining is using the first Atlas Copco ROC D9C Silenced Smart Rig, with silenced mast, for the new $2 billion Brisbane North-South Bypass Tunnel (NSBT) project.
This new “silenced drill” enables the mining company to work longer during the day in a built-up urban area than it would be able to with a conventional drill rig.
The quieter drill also reduces the number of associated occupational health and safety hazards for the company’s employees.
Avko is currently using the ROC D9C Silenced Smart Rig to drill out rounds for explosive charging in a vertical shaft development and subsequently for ground stabilisation drilling.
Avko specifically chose the drill to ensure that the drilling and rock blasting throughout the project would be carried out with maximum accuracy and speed as well as minimal noise and vibration disturbance.
The NSBT project includes a 4.8km tunnel and associated road connections within about 6.8km of overall development.
The tunnel is scheduled to open in the second half of 2010.
