A powerful hoist that can carry nearly 40,000kg of ore to the surface will be installed at Prominent Hill in South Australia as part of OZ Mineral’s ongoing $600m shaft expansion of the mine.
ABB will design and supply its highest payload Koepe production hoist (winder), which has a capacity of 39,400kg, and its strongest ever drivetrain in Australia.
Whilst the hoist ensures safety, efficiency, processing performance and a long service life, ABB will also deliver associated infrastructure and safety systems as part of the 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 4.5Mtpa, increasing to between 4.5-5 Mtpa from 2022 via a trucking operation.
The hoisting shaft provides access to mineral resource outside the current trucking mine plan that would have been uneconomical via a trucking operation from around 2033.
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 is known as a global leader in hoist systems with the last four mine hoists installed in Australia awarded to the global technology leader.
“The project is important for the country’s mining industry and metals security,” said Stuart Cowie, Head of Process Industries, ABB Australia.
“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.
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 products include Safety Plus Hoist Monitor (SPHM), Safety Plus Hoist Protector (SPHP) and Safety Plus Brake System (SPBS) including Safety Brake Hydraulics (SBH).
