Mangoola CHPP wins mining industry awards

Glencore’s Mangoola coal operation in the New South Wales Hunter region celebrated an award-winning trifecta at the recent 2019 Australian Mining Prospect Awards. The site’s Coal Handling and Preparation Plant (CHPP) was named overall Australian Mine of the Year, Coal Mine of the Year and also picked up the award for Excellence Occupational Health and Safety. This is the second time Mangoola has claimed Mine of the Year winning first in 2013.

Ausenco QCC and Downer delivered the greenfield 1,800 t/h CHPP under an engineering, procurement and construction (EPC) contract in 2011. The EPC project was delivered below budget, ahead of schedule and without any lost-term injuries (LTI). Since commencement in 2011, the Mangoola operating team has remained LTI free.

Safety Innovation

Ausenco QCC Manager, Engineering Operations, Craig Sorenson, said the safety record and recent mining awards is a very impressive result and testimony to the dedicated management and operating team of Glencore employees and multiple contracting companies on site at Mangoola.

“The operators of the Mangoola CHPP have always appreciated the effort that the original design team went to in order to provide what is commonly regarded as a benchmark plant, so when the operating team needed an engineering design to safely remove the run of mine feeder wear plates, they again sought the involvement of the Ausenco QCC team. Ausenco QCC designers worked with Glencore’s operations team to design an innovative system to prevent high risk incidents while performing this maintenance activity. We are delighted that our design has contributed to the excellent safety record at Mangoola, and for the management and operations team to have been recognised in such a manner,” Craig said.

In a media release from mine owner Glencore, the Mangoola Coal mine operations manager Nick Slater said: “The health and safety of our staff is our number one priority and our CHPP team has done an excellent job in designing a rail and hydraulic system for one of the higher risk maintenance tasks at the plant - replacing chain feeder plates. I’m delighted their important work has been acknowledged in this way.”

The chain feeder transfers material from the run of mine (ROM) coal bin to the coal sizer, with top and bottom plates bolted to the main frame of the chain-feeder. Historically, replacing these plates is a lengthy task undertaken in restricted spaces and under suspended loads.

The Mangoola innovation uses a hydraulic, trolley-mounted lifting table, travelling on a rail system. It allows old plates to be removed and railed out, and the new ones to be railed in and lifted squarely into position without exposing employees to suspended loads.

Mangoola’s CHPP Manager Chris March said: "By using a combination of rail and hydraulics, we've been able to take our people away from areas of higher risk, as well as significantly reducing the time needed to replace the plates."

Mangoola project background

The original project was an alliance contract to design, construct and commission a plant from raw coal receival, crushing and treatment, plant feed with two stage washing using a dense medium cyclone and spirals process, rejects and tailings handling, product coal storage and handling, overland conveying and train loading.

The project began with early stage studies through to Definitive Feasibility (FEL3), full detailed design and EPC management, including diversion and routing of major high voltage power supply lines, plant and process testing and commissioning to handover.
