ABB says it has won a large order for its highest payload Koepe production hoist, associated infrastructure and safety systems from Australia-based mining company OZ Minerals.
The contract will help to ensure efficient processing performance and a long service life as part of an ongoing $400 million expansion at the Prominent Hill mine in South Australia.
The hoist, which will be designed and supplied by ABB, has a capacity of 39,400 kg and the strongest drivetrain that ABB has ever installed in Australia. ABB specialists will also supervise installation and commissioning.
OZ Minerals’ gold, silver and copper mine began operations in 2009 as an open-pit mine, but it is now an underground mine producing 4.5 Mt/y, moving to between 4.5 Mt/t and 5 Mt/y from 2022 via a trucking operation. The hoisting shaft provides access to mineral resources outside the current trucking mine plan that would have been uneconomical via a trucking operation from around 2033, ABB said.
Installing the Wira shaft will increase the annual underground mining rate, extend the mine life, reduce operating costs, lower emissions intensity, and reduce overall operational risk, according to OZ Minerals.
ABB has been awarded the last four mine hoists installed in Australia.
“The project is important for the country’s mining industry and metals security,” Stuart Cowie, Head of Process Industries, ABB Australia, said. “The local supply chain and workforce also relies on the mine and at ABB we’re enabling it to continue for several more years with increased safety, higher production rates and lower emissions.”
Once operational, the installation at Prominent Hill will have ABB Ability™ Safety Plus for hoists, a suite of mine hoist safety products that brings the highest level of personnel and equipment safety available to the mining industry, the company said. It is the first fully SIL 3 (Safety Integrity Level) certified suite of solutions for hoists, rigorously examined and certified by an independent global functional safety certifying body, and strictly developed in accordance with the International “Safety of Machinery” standard IEC62061, the company said.
The products include Safety Plus Hoist Monitor (SPHM), Safety Plus Hoist Protector (SPHP) and Safety Plus Brake System (SPBS) including Safety Brake Hydraulics (SBH).
