- NSW, Australia
Electrical supply infrastructure and ventilation facility for Australian underground mine extension – PBE Rutherford provide complete electrical solution at Angus Place East for Centennial Coal.
The Location
The Angus Place Mine is owned by Centennial Coal in joint venture with SK Kores Australia Pty Ltd and is operated by Centennial Angus Place. The project was based in the remote location on the Newnes Plateau near Lithgow, New South Wales. Angus Place established a new electrical supply infrastructure and a ventilation facility for an underground mine extension known as Angus Place East. There has been coal mining at Angus Place Colliery for nearly 70 years with Production approval for approximately 4 million tonnes per annum.
The Situation
The requirement was to established new electrical supply infrastructure and a ventilation facility for the underground mine extension based on 66kV and 11kV. The new facility provided the underground longwall operation with improved ventilation and electrical supply through surface to seam shafts and boreholes. The project also required a fully integrated and comprehensive communication system allowing full diagnostics and remote operation.
The Situation
PBE provided a full turnkey solution for the project including design, supply, construction,testing, commissioning and handover. The key features of the projects were:
- ASP1 contestable works involving the augmentation of the existing 66kV overhead Endeavour Energy infrastructure for the 66kV connection point
- 66kV Metering and Switching Station including liaison with the electricity retailer and metering provider (Sub 0)
- 4.5km of buried 66kV transmission lines including dual fibre optic communications
- 66/11kV Transportable 15MVA Substation (Sub 1)
- 1km of buried dual 11kV transmission lines including dual fibre optic communications
- 11kV distribution switchroom including 1.5MVA kiosk transformer for surface supply's and dual PFC Units (Sub 2)
- 11kV underground feeder cables via two 380m deep boreholes suspended from surface to seam including all communication cables
- Fully integrated and comprehensive communication system allowing full diagnostics and remote operation
Requirements
- Permanent electrical infrastructure for mine extensions
- Adequate and reliable ventilation
- Turnkey project and full contractor ownership
- Fully integrated and comprehensive communication system allowing full diagnostics and remote operation
Solution
- 66kV and 11kV infrastructure deployed
- Ventilation system incorporated
- Communications infrastructure for diagnostics and remote operation
- Project delivered on time and within budget
