Queensland Mines Rescue Service (QMRS), in partnership with Anglo American, has commissioned a critical new piece of mine rescue equipment for use across underground mines in the Queensland mining industry.

A funding commitment, in excess of A$2.3 million ($1.6 million) from Anglo American, enabled QMRS to purchase the Queensland mining industry-first Shaft Rescue System (SRS), a mobile truck-mounted emergency system to assist in underground rescues.

The commissioning at the Aquila mine followed a 2019 commitment from Anglo American Australia then-CEO, Tyler Mitchelson, to wholly fund the equipment for the QMRS.

Chief Executive Officer of QMRS, David Carey, acknowledged Anglo American for funding the equipment and supporting QMRS in its design and engineering.

“While we hope we never need to use it, the SRS will form part of the emergency response plan for every underground mine site in Queensland and we’re grateful for Anglo American’s support in delivering it,” Carey said. “The SRS lowers interchangeable cages into mine shafts to rescue trapped miners and is equipped with a world-first intrinsically safe directional Wi-Fi communications system that can be used safely underground.”

The Wi-Fi enables radio communications from the rescue cage to the surface, captures and shares real-time video and sends data from a gas monitoring system, according to Carey.

QMRS says the SRS has interchangeable cage options and over 1,200 m of rope on the drum for use in deep shafts. It is engineered with multiple fail-safe braking systems, hydraulically powered from the Volvo FMX 10*4 truck engine, which also has a back-up power system.

Carey added: “This equipment will make a meaningful difference to our emergency response capabilities in Queensland and will be housed at our Dysart headquarters in the heart of the Bowen Basin, so it’s close by if ever required.”

Head of Safety and Health at Anglo American’s Steelmaking Coal Business, Marc Kirsten, said the company was pleased to support QMRS in delivering the SRS for all those who work underground in the mining industry in Queensland.

“QMRS supports our industry with leading edge emergency response capability and support, and we are pleased to have been able to support them in turn, by providing this vital and potentially life-saving equipment,” Kirsten said.

“The SRS will improve emergency response capabilities across all underground mines in the Queensland mining industry, and it was important to us to make this investment in industry safety.”

Anglo American operates five steelmaking coal mines in Queensland’s Bowen Basin, three of which are underground.

Coal technology, Mine operation news, Mining equipment, Mining services, , , , , ,

National Group says its contract mining operation, National Mining Services, is to supply services to Yancoal’s Moolarben mine in the Western Coalfields of New South Wales, Australia.

As part of a three-year mining services contract, with an option to extend for a further two years, National Mining Services will provide works that include the safe pre-stripping of a minimum of 15 million bank cubic metres (Mbcm) of overburden each year at Moolarben.

National Mining Services will use National Group’s ultra-class mining equipment on the contract, including Liebherr R9800 excavators, Liebherr T282 dump trucks and other ancillary equipment.

“This is a significant contract in National Group’s history,” National Group founder and Managing Director, Mark Ackroyd, said. “We are grateful for Yancoal’s ongoing support for National Group and for the opportunity to contribute to the world-class Moolarben open-cut coal mine. National Group looks forward to helping Yancoal achieve its goals at Moolarben.”

The Moolarben contract continues a strong period of growth for National Group in the coal industry. In January 2022, National Group extended an equipment contract for Anglo American Australia on its two expanding open-pit coal mines at Capcoal in the Bowen Basin in Central Queensland (Lake Lindsay and Oak Park).

“National Group is proud to be part of the Australian coal industry,” Ackroyd said. “We intend to expand our long-term presence in the coal sector, help more companies export high-quality Australian coal, and create jobs for regional communities.”

The Moolarben contract expands National Group’s footprint in NSW. In 2021, Newcrest awarded National Group a surface-mining contract at its Cadia gold mine in central NSW, where it is supplying Caterpillar 994K and 988K large wheel loaders, Caterpillar 793 dump trucks and the Hitachi ZX890 excavator.

“National Group continues to grow and diversify its NSW operations,” Ackroyd said. “We have significant long-term contracts in coal and gold, and a strong pipeline of opportunities for sustained growth in NSW. National Group has created well over 100 regional jobs in NSW in the past two years. We intend to create plenty more.”

Ackroyd says the Moolarben contract diversifies National Group in others ways.

“Our company is best known as a leading supplier of heavy-earthmoving equipment,” he said. “The Moolarben contract expands our work in mining services and further strengthens National Group’s unique end-to-end offering and its operational diversification.”

National Mining Services is well-positioned to take on more work in mining services by providing mining and infrastructure services to National Group’s major open-pit mining clients, it said. “The business has extensive capabilities in large-scale mining projects, meeting production requirements in excess of three Mbcm per month of waste and coal.”

Ackroyd says National Mining Services’ position within the National Group is a competitive advantage.

“Through National Group, National Mining Services has access to one of the country’s most advanced mining fleets, a large supply of experienced labour and access to capital,” he said. “Most of all, National Mining Services has a great team.”

Weba Chute Systems wins retrofit design work at Mpumalanga coal mine

Coal technology, Mining equipment, Mining services, Mining software, , , , , ,

When a coal mine in South Africa’s Mpumalanga province needed to replace its high maintenance conventional transfer chutes, it looked to Weba Chute Systems for the best custom-engineered design, the manufacturer says.

Weba Chute Systems is currently busy with designs that will pave the way for the retrofitting of over a dozen chutes at the mine. Eight of the units are silo discharge chutes, transferring coal from the operation’s run-of-mine feed to its coal processing plant. Another four chutes are to be replaced in the plant itself, while there is another chute located between two related feed conveyors.

“The main objective of the new bespoke chutes is to ensure stable supply to the plant, and from there to the nearby power station,” Dewald Tintinger, Weba Chute Systems’ Technical Manager and Designer, says. “The existing equipment is demanding too much maintenance, leading to unacceptable levels of downtime.”

The key to improved uptime and extended chute lifespan is the company’s flow control principles in its designs. The chutes in the plant, for example, must deal with oversize material of between 150 mm and 500 mm in size.

“Handling these large particles, chutes are exposed to high levels of impact and wear,” Tintinger says.“With the controlled flow philosophy of our Weba ‘cascade’ chute system, we control both the velocity and the impact.”

Commenting on other aspects of the custom designs, Tintinger says the transfer points will include features such as dead-boxes to create a lining from the mined material itself. This reduces the wear on the chute’s metal surfaces, extending the maintenance intervals and delivering more uptime. He highlights that the processing plant feeds the power station directly through two overland conveyors.

“This is a highly efficient model for delivering coal, but it demands that all elements of the materials handling system are working together,” he says. “Any disruption of coal flow caused by a transfer chute can cause costly delays, and render coal delivery unreliable.”

He notes that the mine has had good experience from the many other Weba chutes already installed at this operation, and is now standardising on this internationally accepted transfer point design for better results.

Designs and engineering are conducted in-house by Weba Chute Systems’ experienced team, using the latest software and finite element analysis tools for testing.

The design work is expected to be completed around the middle of 2022. Thereafter the mine will be in a position to contract the fabrication and installation work.

NRW Holdings Limited companies Golding Contractors and DIAB Engineering have banked some significant contracts in the mining space, the biggest of which is a Mining Service Agreement with Wonbindi Coal Pty Ltd at the Baralaba North Mine in Queensland.

The Baralaba North award is valued at around A$800 million ($546 million) and continues the strong relationship between Golding and Wonbindi where Golding has provided the contract mining services at the Baralaba North Mine over the last four years.

The scope of work remains the same and includes maintaining and operating a client-owned fleet of equipment, producing an ultra-low volatile pulverised coal injection product. The pact commenced on July 1 and follows on from a Binding Letter of Intent the two companies signed earlier in the year.

DIAB Engineering, meanwhile, has been awarded two contracts with a value of circa-A$78 million.

At the Lynas Rare Earths Processing Facility in Kalgoorlie, Western Australia, DIAB has been awarded a contract for a key component of the facility, being the construction of the Filter Building used to process and further concentrate the rare earth. The works to be performed include the supply, fabrication and erection of the Filter Building, the installation of associated equipment and piping, and electrical and instrumentation installation.

DIAB will carry out all the circa-1,500 tonne fabrication works for the Filter Building at its facilities in Geraldton using around 80 local Midwest team members. A construction workforce of 60-80 will then be mobilised to site progressively over the coming months.

Lynas Kalgoorlie Pty Ltd, a wholly owned subsidiary of Lynas Rare Earths, is the only scale producer of separated rare earths outside of China. It mines and processes rare earth ore at Mt Weld, in the north-eastern Goldfields region of Western Australia. Lynas’ new processing facility in Kalgoorlie will treat rare earth concentrate from Mt Weld to produce a rare earth carbonate.

At Rio Tinto Iron Ore’s Tom Price mine in Western Australia, DIAB Engineering, has secured the supply, fabrication and installation of multiple dust suppression systems to be utilised on the Tom Price and Western Turner crusher and conveyor systems. These systems will assist in improved control and suppression of dust generated from processing activities, reducing the impacts on personnel and plant operations, it says. The project will run for approximately 12 months, employing 60 people at its peak.

Australia-based Field Solutions Holdings Limited says it has been selected as exclusive preferred supplier for enterprise Managed Desktop, Network and general IT services for Kestrel Coal on a five-year contract term.

Coming with revenue of circa-A$25 million ($17 million), the contract extends Field Solutions’ existing connectivity provision relationship with Kestrel Coal, while leveraging its Regional Australia Network telecommunications infrastructure.

“The award of this enterprise contract to FSG validates and reinforces our strategy to build infrastructure and deploy full-time resources into rural, regional and remote Australia,” Andrew Roberts, FSG CEO, said.

FSG has been operating and building infrastructure across central Queensland for the past five years, providing residential, business and enterprise telecommunication services from its Emerald regional headquarters.

This win consolidates FSG as the largest Managed Services organisation in Emerald and surrounding areas and will see FSG expand its local operations at its Emerald Regional headquarters, the company said.

“Field Solutions’ Regional Australia Network services the mining regions northeast and west of Emerald and FSG has provided connectivity services to Kestrel Coal for three years, together with other mining and agribusiness customers,” Roberts said.

Kestrel Coal ran a competitive process to select FSG as its preferred IT partner, FSG says. Its mine is 51 km northeast of Emerald and was managed by Rio Tinto until 2018. It is one of the largest coking coal mines in the world, with an estimated 158 Mt of reserves.

Roberts added: “Last year, FSG acquired Infrastructure as a Service, cloud and ISP provider TasmaNet, which bolstered FSG’s existing capability to deliver enterprise grade managed and cloud services. This contract win highlights the value of our recent TasmaNet acquisition.”

FSG says it is currently finalising commercial terms for the Managed Network and Managed Services contracts and expects the transition to be completed by the end of July. Additional IT and procurement services will be sourced on an as-needs-basis over the course of the five-year term.

The company is continuing to pursue several key mining services contracts in central Queensland, according to Roberts.

“Mining and agribusiness areas across Australia will continue to be key focus areas for FSG to deploy its own infrastructure and services,” he said.

These areas will be serviced by FSG’s 4G and 5G Regional Australia Network, which is currently under construction.

Zululand Anthracite Colliery (ZAC) says it has commissioned a new 25 t/h filter press at its coal washing plant, in Emakhalathini, KwaZulu-Natal, South Africa.

The filter press, from South Africa-based Filtaquip, removes slurry from the water used in the coal washing process. It will aid in preventing incidents such as the coal slurry spill, which occurred at ZAC after the end wall at Slurry Pond 3 failed on December 24, 2021, the company noted.

ZAC Engineering Production Superintendent, Howard Atkinson, explained: “The filter press filters slurry-laden water and removes all the ultrafines from the water to enable reclaimed water to be reused in the beneficiation process.”

The filter press plant, which cost R14.5 million ($933,660), was commissioned on May 10, 2022, and was in full production by May 16.

Filtaquip says its filter presses have high pressure technology for up to 21 bar feed pressure; Q-Shift plate movement technology for efficiency; external filtrate discharge; and an automated and maintenance free shaker system.

The conservation, protection and management of water is a top priority for ZAC, it said.

ZAC GM, Wayne Rowe, said: “The principal aim of ZAC’s sustainable water management policy is to minimise and reduce freshwater consumption in all our operations.”

ZAC operates an underground, deep level, narrow seam operation, using both continuous miners and drill and blast mining techniques. ZAC’s current life of mine is up to 2027, but there are undeveloped known resources still to be considered in future, it says.

Hatch identifies opportunities to cut Australian tailings generation by as much as 30%

A new report from multi-disciplinary engineering, operational and development project, Hatch, estimates Australia’s mining waste can be reduced by 30% using already available technologies.

One of the biggest challenges currently facing the mining industry is managing the volume of tailings generated as minerals mining ramps up to meet the demands of the transition to renewable energy.

Undertaking an in-depth analysis to identify the technologies required to reduce or eliminate tailings of six key commodities (copper, gold, nickel, iron ore, coal and bauxite), Hatch investigated how tailings production would be impacted by applying the key technologies ‘themes’: advanced geometallurgy, ore sorting, advanced sensing and particle sorting, in-situ extraction, and preferential fracturing.

The company’s analysis revealed that technologies available today could reduce tailings by 20-30%, also identifying that, in the next 10-20 years, the integration of these technologies in future projects or expansions could provide an opportunity to reduce tailings by more than 50%.

Managing Director of Australia and Asia at Hatch, Jan Kwak (pictured), says the challenge of reducing tailings is a complex effort that is best solved utilising the innovative capacity of the entire mining supply chain.

“A balanced spread of researchers, METS (mining equipment, technology and services) companies, and operators in the mining industry are actively commercialising technologies,” he said. “Half (50%) of stakeholders identified are METS companies, whose core business is the supply of equipment and services of these technologies, indicating commercialisation is underway. This group was also present across the technologies that our analysis has shown to have higher TRLs (Technology Readiness Levels).”

The TRL ranking system measures the maturity of technologies, whereby Hatch graded technologies from zero (idea stage) to nine (commercial application).

For in-situ mining and preferential fracturing technology themes, there is a larger representation of research organisations and partnerships. This suggests collaboration is required to advance technological development, according to Hatch.

“It is vital that these stakeholders are highly engaged in the tailings reduction challenge in order to achieve the greatest cut through and introduce real change and advancement in the reduction of tailings, which will be needed to support the increase in mining activity while meeting emissions reduction targets,” added Kwak.

Batchfire invests in six new electric drive Komatsu 930E-5 trucks for Callide mine

Coal technology, Mine operation news, Mining equipment, , , , ,

More than 60% of Batchfire Resources’ pre-strip mining fleet is now made up of electric drive dump trucks, after six new Komatsu 930E-5 ultra-class vehicles arrived at its Callide coal mine operations in Queensland, Australia.

The latest investment in six haul trucks maintains Batchfire’s policy of growing the proportion of electric drive machines within its overall fleet capacity, it said. The two draglines operating at Callide in central Queensland are electric powered.

Passing the 60% electric drive milestone significantly reduces the amount of carbon dioxide generated during pre-strip mining activities, according to the company. The new Komatsu 930E-5 dump trucks come with around 8% less emissions intensity than the older diesel-mechanical models being phased out, it said.

In addition, these new dump trucks will enhance productivity and deliver improved safety outcomes for Batchfire’s team of experienced operators, it said.

“Continuing to reduce the Callide Mine’s environmental impact and carbon footprint is a key priority for Batchfire Resources,” Allan Fidock, CEO of Batchfire, said.

“Batchfire is an agile business which places sustainability at the heart of our operations. We are constantly seeking new opportunities to reduce our overall emissions and this is reflected in our procurement policy.

“The Komatsu 930E-5 provides us with clear advantages in emission control, productivity and safety so investing in this market-leading model is the right solution for our business.

“In addition to these new machines, we expect to add a further three 930E-5s in the coming months, allowing us to phase out some of our older diesel-mechanical drive models.

“Maintaining our fleet’s high standards of reliability and efficiency, while increasing the size and capacity of the machines we operate, will result in productivity gains that benefit our entire business and emissions reductions that benefit the world in which we operate.”

Fidock emphasised that the procurement of diesel-electric drive machines was one aspect of a broader sustainability strategy at Batchfire.

“Our dedicated ESG and Development team is working with the board to strengthen ESG practices and identify opportunities to further reduce our emissions,” he said.

“This includes progressing the renewable energy projects, which are a central pillar of our transitional energy business model.

“We have also reduced fuel consumption across the diesel-mechanical drive and diesel-electric drive pre-strip and coal mining fleets by investing in MaxMine and other smart solutions. This data-driven approach to operations has improved our operations efficiency.”

MaxMine’s sensors and cloud-based processing system (MaxCube) extract and process 10,000 times more data from mining equipment and operator behaviour than incumbent systems, according to the software company, driving efficiencies and productivity.

The coal that Batchfire produces for the domestic and export market is the lowest fugitive emission energy coal mined anywhere in Queensland, according to the company, helping to reduce greenhouse gas emissions in power generation within Australia and overseas.

Bravus reinforces Carmichael local supplier relationship with BCF Concreting contract

Coal technology, Mineral project development, Mining services, , , , ,

Bravus Resources has added BCF Concreting to its list of suppliers at the Carmichael coal mine, in Queensland, Australia.

The 100% Indigenous-owned business has been engaged to supply concrete to the operation, with the contract adding to the more than A$1 billion ($743 million) that has been paid to regional Queensland contractors and businesses since construction on Carmichael began.

Michael Davis, Managing Director of BCF, said the company was prepared to deliver extra concrete at short-notice for the mine.

“We were able to step in and work with Bravus at short notice because our technology enables us to both mobilise quickly and mix the right kind of concrete remotely and with precision,” he said.

“We had a team of six and one of our three volumetric mixing trucks on Bravus’ site within a few days and producing concrete not long after that.

“I have to say the Bravus commercial team was also great to work with, and the smoothness of that contracting process, together with the advantages of our new-to-industry technology, meant we were able to get this job done so efficiently.”

Bravus Mining and Resources CEO, David Boshoff, commended Davis and his Rockhampton-based team on their work.

“The Rockhampton region is a world-class mining service centre, but BCF Concreting blew us away with their professionalism, mobilisation time and technology-focused solutions,” he said.

“Responsiveness and on-time delivery is so important for us as we put the finishing touches on the construction, testing and commissioning phase of the project and move into full operations.”

BCF Concreting has a 30-year history and relocated to Rockhampton in 2019, drawn to the region by the promise of work with major projects.

A Torres Strait Islander, Davis said the company had built strong partnerships with Central Queensland’s Traditional Owner groups but had been waiting for the right opportunity to prove their capabilities on a major construction or civil project.

“We had done some subcontracting work on the Carmichael Project before but to be engaged by Bravus directly is a big step forward,” he said.

“We work with technology that’s new to the concreting industry, so part of what we do is about educating clients that the way it’s been done in the past isn’t necessarily the best way.

“Our volumetric mixers are similar to a mobile batching plant mounted onto a truck – we can get to site and start producing concrete within half an hour.

“We are getting traction, though, and as well as working with Bravus, we recently secured a long-term precast supply contract for a pipeline project in Central Queensland.

“The hope is as we win more major project work we can look at relocating the manufacturing arm of our business to Central Queensland to boost skilled employment for First Nations people even further.”

Carmichael has the capacity to produce 10 Mt/y of coal.
