NRW Holdings Limited’s wholly owned subsidiary, Golding Contractors Pty Ltd (Golding), has signed a mining services agreement (MSA)
with Stanmore SMC Pty Ltd (Stanmore) at the South Walker Creek (SWC) mine in central Queensland, Australia.

The MSA has a total value of approximately A$1.6 billion ($1.07 billion) over a five-year term, commencing in January 2026.

The scope of the MSA includes operating and maintaining eight fleets of heavy mining equipment to remove overburden and mine steel-making coal consistent with current contractual arrangements. The Golding-owned assets employed consist of those assets purchased as part of the HSE SWC contract acquisition that completed on August 1, 2024.

South Walker Creek is an open-cut mine 35 km west of Nebo in Queensland’s Bowen Basin. The mine has been operating since 1996 and adopts a multi-bench, open-cut mining method uising a dragline, and truck and hydraulic excavators. With a mine life of 25-plus years, South Walker Creek produced 4.9 Mt of high-quality low volatile PCI coal in the 2021 financial year. Stanmore Resources acquired BHP’s 80% interest in BMC in May 2022, becoming the operator of South Walker Creek.

The MSA provides employment to approximately 650 personnel mostly residing within the region.

NRW Chief Executive Officer, Jules Pemberton, said: “I am delighted to announce that NRW has been awarded this contract with Stanmore,
allowing us to build on the successful relationship we have had with Stanmore over a long period. NRW’s drilling and blasting subsidiary ADB is currently working with Stanmore at SWC and Golding now renews its prior association. With the addition of the SWC MSA, NRW’s order book climbs to a record A$7 billion. I look forward to a successful partnership with Stanmore.”

Kestrel Coal Resources has announced that it has partnered with the Queensland Government, through the Treasury’s Low Emissions Investment Partnerships (LEIP) program, for the funding of a 30 MW coal mine waste gas power station project.

The project will allow the company to expand its gas drainage system to capture more gas, preventing it from being released into the atmosphere and repurposing it for power generation.

The 30 MW power station will generate enough electricity to power up to 40,000 homes and increase the reliability of the electricity grid in the region.

This LEIP funding initative is a significant step forward in delivering Kestrel’s emissions reduction targets as it continues to sustainably supply the steelmaking industry, Kestrel says.

EML369 Multi-Load

An evolution in ‘hands free’ exploration drilling

Automation, Mining equipment, Mining services, , , , , , , , , , , , , , ,

Evolution Drill Rigs out of Queensland, Australia, believes it has come up with a cost-effective and time saving solution to one of the most labour-intensive parts of the exploration drilling operation: handling drill rods.

Its Evolution EVO Multi-Load drill rod handling system is a true “hands free” diamond drill rod & casing handling and storage system, according to General Manager, John Slattery, explaining that it has been designed to work with most current exploration drill rigs, including the Evolution FH2000 & FH3000 and Sandvik DE840 & DE880 drills.

Evolution is not the first to come onto the market with a hands free rod handling system – readers may be thinking of Boart Longyear, Epiroc, Major Drilling, MEDATech Engineering’s Borterra division and others here – but Slattery is convinced the EVO Multi-Load system has the potential to make the biggest market impact.

“By choosing to design a system to work in conjunction with existing rig designs, the drilling contractors are able to utilise existing equipment with a few small changes,” he told IM. “Rather than invest in completely new drill rigs and handling systems, they can save significant capital outlay by investing in the EVO Multi-Load system.”

The other benefit of working with the existing rigs is the increased efficiency of rod tripping operations by using the existing rig main winch, he explained. “The ability to trip rods in 9-m lengths on deep holes during bit changes and ‘Navi-runs’ is a significant time saving method when compared to tripping rods in either 3-m or 6-m lengths as some other rod handling systems are limited to,” Slattery added.

The company already has one company speaking to these benefits too, with South32 recently running a 12-month trial of the EVO Multi-Load prototype at the Jessica and Cararra exploration projects in the Northern Territory of Australia. The company conducted this trial with its contract partner DDH1 Drilling, owned by Perenti, and said it was a “success” with plans to deploy the system on other South32 exploration projects in its 2025 financial year. South32 also provided funding to support Evolution’s prototype field trial and ensure the equipment was suited for ongoing use.

Slattery said the company’s ongoing testing of the prototype rig – in the workshop and the field – had led to an ongoing improvement plan ahead of commercialisation.

“Our engineering staff have worked closely with our customer DDH1 Drilling during the EVO Multi-Load development and our workshop team continued this during the testing phase and field trials,” he said. “We identified some areas for improvement during the workshop testing, which were incorporated into the rod loader prior to the field test: the sequencing of adding and removing rods from the loader has simplified the operation and helped with productivity.

“We have a few more updates in the pipeline to streamline the tripping process and increase overall productivity.”

This process has been aided by collaboration with DDH1 Drilling, according to Slattery, allowing the company to understand the contractor’s methods and requirements for handling rods during deep coring and directional drilling. “This allowed us to further develop our concept into a working prototype,” he said.

DDH1 Drilling’s experience with the use of several other types of drill rod handling system has allowed Evolution to benchmark operational cycle times against competitor products and confirm the productivity of the EVO Multi-Load system, he added.

Outside of the top head drive multi-purpose drills the Evolution system has already been designed to work on, there is the prospect of expanding this list further with a few small tweaks.

“In regions outside of our native Australia, such as Africa and South America, there is a large existing fleet of multi-purpose drills that could most likely use the system,” Slattery said.

This speaks to the faith Slattery has in the global potential of the system.

“We believe the majority of the drilling contractors and mining companies are interested in improving the operational safety around drilling projects in general, and drill rod handling is a big part of that,” he explained. “The EVO Multi-Load drill rod handling system has been designed around the needs of deeper core and directionally drilled holes, large volumes of drill rods, as well as the need to deal with different pipe and casing sizes. These more complex drilling programs are normally undertaken by the larger mining companies that have been calling for reduced human involvement in the drill rod handling process for some time.”

He concluded: “Our system has been designed to work with a range of rod and casing sizes and is flexible enough to be used on any brownfields exploration drilling program that involves the need to drill deep holes.”

Anglo American introduces teleremote dozing at Capcoal Complex

Automation, Coal technology, Mine operation news, Mining equipment, Mining services, Steel and iron ore, , , , , ,

Dozer operators at Anglo American’s Capcoal Complex in Queensland, Australia, are in training to embrace remote control technology to improve operator safety on site, the company says.

The operation, near Middlemount, is trialling a remote-controlled stockpile dozer ahead of plans to retrofit the entire fleet.

Anglo American, which operates five steelmaking coal mines across the Bowen Basin, will reduce in-cab dozer exposure time by 45,000 to 75,000 hours a year once the technology is fully deployed across all sites.

Coal handling and processing plant dozer operators are the first to gain experience operating teleremote dozers as part of a pilot program to reduce exposure to concealed stockpile voids. The pilot includes the retrofit of a stockpile dozer with the latest Wi-Fi-enabled technology to set up connectivity between the machine and operator chair in the control centre.

An Anglo American Australia spokesperson told IM that the company had collaborated with RCT on this trial, leveraging RCT’s OEM-agnostic ControlMaster® solution.

Capcoal General Manager, George Karooz, said it was the first time the remote control dozer technology would be used at Anglo American’s Australian operations.

“Upskilling our workers in this new technology is paramount to its success because their expertise is irreplaceable, even when the work is done remotely,” he said. “In pursuit of safety and efficiency, the mining industry has been a constant driver of innovation for generations.

“Operating our fleet of dozers from a safe distance will reduce the number of hours in the cab and fully remove our operators from the dozer seat in what is another significant advancement in autonomous mining.”

Acting Automation Operations Manager, Matthew Wakeford, said operators were being trained in how to control a dozer from a remote control centre, in a transition that has been nine months in the planning.

“We are re-imagining mining to improve people’s lives. From a business safety perspective, this will remove our coal miners from the hazards of working with voids in our coal stockpiles,” he said. “We are starting with small steps as our workers adjust from the ‘feeling’ of manual operation to remote control with cameras and computer screens.

“We already have microphones in the machine sending the sound back to the operators along with six cameras on the dozer itself – as well as cameras around the stockpile which can all be adjusted remotely.

“Through feedback, we are now looking at whether we can adapt the chair to tilt and provide movement feedback through the joystick the same way our operators would sense the stockpile beneath when manually operating the dozer.

“We’re starting with just one dozer, but the plan is to ramp up and retrofit the entire fleet – that’s 13 in total across our Capcoal and Moranbah operations.”

Anglo American launched the trial in January, with the pilot program involving the setup of a room in a building in close proximity to the stockpile. The spokesperson added: “Once it’s rolled out to further machines across the Australian business, the teleremote dozer operators will be in a dedicated control room.”

NRW Holdings Limited’s wholly owned subsidiary, Golding Contractors Pty Ltd, has executed an agreement to acquire the mining services contract, associated fleet and transfer of the employees that HSE Mining Pty Ltd has deployed to Stanmore Resources Limited’s South Walker Creek (SWC) mine site, in Queensland, Australia.

The transaction value of A$85 million ($56 million) less assumed employee liabilities of approximately A$15.3 million, will be funded via NRW’s asset finance facilities.

The transaction will see Golding employ approximately 550 HSE personnel and operate the heavy mining equipment presently deployed at SWC. The mining services contract to be novated to Golding as part of the acquisition is expected to generate annual revenue of approximately A$250 million, and unless further extended by agreement between Golding and Stanmore, expires in August 2025.

South Walker Creek is an open-cut mine 35 km west of Nebo in Queensland’s Bowen Basin. The mine has been operating since 1996 and adopts a multi-bench, open-cut mining method uising a dragline, and truck and hydraulic excavators. With a mine life of 25-plus years, South Walker Creek produced 4.9 Mt of high-quality low volatile PCI coal in the 2021 financial year. Stanmore Resources acquired BHP’s 80% interest in BMC in May 2022, becoming the operator of South Walker Creek.

Jules Pemberton, Managing Director and CEO, said: “I am delighted that NRW has been successful in acquiring the HSE Mining assets and inventory and securing the novation of the mining services contract with Stanmore at South Walker Creek.

Coronado Global Resources looks at running updated waste mine gas truck trial at Curragh operations

Environmental, Mining equipment, Mining services, Steel and iron ore, , , , , , , , ,

Coronado Global Resources’ plan to capture and use open-pit waste mine coal gas from its Curragh operations in the Bowen Basin of Queensland, Australia, are accelerating, with the company confirming at its AGM last week that first gas from pilot wells was achieved in January 2024 with better than anticipated flow rates.

Curragh has been operating since 1983 and was acquired by Coronado in 2018. It is made up of two active open-pit mines – Curragh South and Curragh North – which are serviced by four large draglines, one electric rope shovel, 13 truck and excavator fleets and two coal preparation plants. It produces high-quality, low-vol hard coking coal, semi-soft coking coal, pulverised coal injection and thermal coal.

Curragh’s gas project is targeting the capture and beneficial use of open-pit waste mine coal gas from operations, with priority downstream use cases being for power generation and use  as a diesel substitute in mining fleets.

The company says it now has wells operational, with surface production facility installation works complete and thee anticipated flow rates from first gas achieved in January exhibiting better than anticipated flow rates.

The next steps for the project are to run an updated converted gas truck trial to test feasibility of transitioning to waste mine coal gas conversion on more trucks.

As part of Coronado Global Resources’ emissions strategy, the company conducted a trial to test gas-converted haul trucks, working with its partners Mine Energy Solutions (MES) and Thiess. Over an eight-week period beginning in July 2023, it converted a single 793F haul truck to dual fuel and operated it within a normal production environment. Results from the trial proved that the operational performance of the trucks remained within the normal range of a diesel truck, it noted.

The company said in its recently released 2023 sustainability report: “We also developed an understanding of the key partnerships and requirements for larger-scale deployment and the challenges we need to overcome for operational readiness.”

Achievements and findings from the trial included:

  • Saving of 19,200 litres of diesel;
  • A 17-20% reduction in diesel exhaust pipe CO2 emissions;
  • No observed decrease in truck horsepower, engine life or other components due to burning compressed natural gas (CNG);
  • More than 320 hours of dual-fuel operation and 547 hours of overall operation;
  • No observed decrease in travel time, cycle time or speed on grade; and
  • Operators’ positive feedback that vehicles operated similarly to non-gas 793F haul trucks.

BHP BMA’s Goonyella met coal mine receives ABB electrification upgrade

Coal technology, Communications in mining, Mine operation news, Mining services, Steel and iron ore, , , , , , , , , ,

Sustainability, employee protection and operational insights are the drivers of a cutting-edge electrification upgrade at BHP BMA’s Goonyella Riverside Mine in Queensland, Australia, ABB says in a recent case study.

At the BHP-Mitsubishi Alliance (BMA) conjoined metallurgical coal mines Goonyella and Riverside in Queensland’s Bowen Basin, Subra Nedunuri, Senior Project Manager, Goonyella Riverside Mines (GRM), is responsible for delivering capital electrical projects without compromising environment, safety, quality, or mining schedules.

When a 43-year-old section of Goonyella Riverside’s power infrastructure became unreliable, Nedunuri began designing an upgrade with ABB capabilities, which protect employees, equipment and the environment, and enable predictive maintenance of 16 pumps critical to the mine’s operation.

Nedunuri said: “A rehabilitation project to move earth from one side of the mine to the other may cost $20 million, but in contrast this $3 million electrical upgrade can save lives and hundreds of millions of dollars in downtime.”

To power the coal wash treatment plant, pumps are used to direct water for reuse or into tailing dams: without them the plant can’t operate. In the past, the now obsolete electrical system communicated only three states of condition for the pumps operation – “On”, “Off” or “Fault”. The system had no protection against arc flash incidents (explosive releases of energy when an electrical arc travels through ionised air to ground or another part of the electrical system), which endanger the lives of service technicians and nearby workers.

For the upgrade, BMA wanted not only the safest switchgear to protect its employees, but a human-machine interface (HMI) that would enable remote and on-site monitoring and control of the electrical system and pumps around the clock.

ABB’s system-integrated Ultra-Fast Earthing Switches (UFES) formed the basis of GRM’s upgrade with safety, and protection of the people within the vicinity of the equipment in mind.

“The switch is installed into the panel to prevent an arc flash, if it occurs it will be detected and switch off the power in less than four milliseconds,” Nedunuri said. “In addition to UFES-enabled switchboards, the mine wanted to take advantage of new and trending technology in the form of digital communications between the switchboard and the plant.”

ABB Ability™ Electrical Monitoring and Control for Distribution Networks, known as ZEE600, integrates diverse devices from a variety of suppliers, under the IEC 61850 standard of communication preferred by BMA, ABB explained. At GRM, this condition monitoring solution harnesses the real-time diagnostic data of substation equipment and electrical assets – primarily the pumps – to alert on-site teams to respond with preventive maintenance.

“Via the HMI, you can actually see the health of the pumps, motors and starters – everything. Our analysis and improvement team also continuously collect the data and analyse it for troubleshooting and future enhancements,” he said.

Nedunuri said it’s all connected back to plant supervisory control and data acquisition (SCADA).

Installation and commissioning of the upgraded system took place during the mine’s biannual three-week-long scheduled maintenance shutdown in August/September 2022.

Prior to the shutdown period, Nedunuri constructed the system at ABB premises in Brisbane. Together with the ABB technicians, they matched cabling inlets and outlets with a template of the GRM system.

Henry Lin, Project Manager for Electrification Service at ABB in Brisbane, says ABB customers need to reduce the risk of costly downtime. “Our main objective in these projects is to ensure that our customer’s assets operate at peak performance levels and are available as required,” he said.

BMA has performed much research on the digitalisation of its mines and the ongoing upgrade of infrastructure involves a constant rollout of individual projects. When it comes to the safety and reliability of electrical infrastructure, Nedunuri said the company doesn’t compromise, regardless of the cost.

“All upgrades must not only comply with Australian Standards, but also require ongoing modifications to meet the higher bar set by BHP BMA to make sure it runs efficiently and effectively into the future,” he said.

“I feel proud that I eliminated a huge risk to the business through the pump electrification project. We are protecting people using the new system with arc flash mitigation and at the same time, the monitoring and control enabled by ABB ZEE600, not only improves pump efficiency, but also adds a lot of functionality – it’s easy to operate and easy to maintain.”

BMA and ABB are collaborating on a pipeline of further potential upgrades to existing on-site installations, with each project planned to deliver greater safety, reliability and sustainable growth, ABB says.

The scope of the variation includes operating and maintaining a second 600-t excavator and 220-t rear dump truck fleet to mine pre-strip overburden, increasing the full scope of the agreement to two 600-t mining fleets.

The variation is valued at approximately A$160 million ($105 million) and will commence in April 2024 using existing owned fleet and supplemented with hire equipment, NRW says.

NRW subsidiary Action Drill & Blast Pty Ltd has also been awarded the following contracts in Queensland:

  • Blasthole drilling services for Batchfire Resources at the Callide coal mine. The contract, valued at circa-A$52 million over five years has commenced and will use a workforce of some 40 personnel;
  • A 12-month extension to supply agreement with Dyno Nobel Asia Pacific Pty Ltd for a Bowen Basin mine valued at A$30 million; and
  • A services agreement involing drilling for a central Queensland mine. This has a contract term of three years on an agreed rates basis with an estimated value of A$28 million.

These contracts will also use existing ADB-owned equipment where applicable, the company said.
