Full project details
Laing O’Rourke was responsible for the design, manufacture, supply, installing and commissioning of an upgrade to Centennial’s coal-handling plant at Cooranbong, New South Wales. An additional coal-handling export facility was integrated into the plant, which now includes a truck-loading system and an export stock pile stacker.
The Cooranbong coal-handling plant receives coal from the nearby Centennial coal mine. Run-of-mine coal is delivered via an underground south drift conveyor to a 2000 tonne storage bin on the surface, adjacent to the existing coal-processing plant.
The upgrade involved:
- modifying the existing run-of-mine bin interface to a new 1200 tonnes per hour truck-loading bin and stockpiling system
- installing a fully automatic twin truck-loading system
- installing 2000 tonnes per hour rated conveyor systems, including a truck bin transfer conveyor and a new export stockpile conveyor
- installing all the required electric-powered reticulation and control systems
- reinstalling all the required reticulated services to the run-of-mine bin
- installing the separate washdown and fire-fighting and stockpile dust suppression spray systems and tie-ins to existing services
Laing O'Rourke drew on its multidisciplinary engineering and construction expertise to complete the upgrade within a tight timeframe. The civil works and piling were undertaken by Expanded (a Laing O’Rourke subsidiary company). A modular, pre-engineered stressed skin conveyor system manufactured by Redispan (also a Laing O'Rourke company) was incorporated into the upgrade.
Fully operational, the upgraded plant now offers the capacity to increase the output of the mine. This allows for the export of Centennial’s high-grade coal to the open market, while the mine continues to feed the Eraring Power Station and meet its full requirements.
