Sandvik equipment starts to arrive for OceanaGold’s Macraes expansion

OceanaGold Corp has received the first of three new Sandvik machines at its Macraes gold mining operation on the South Island of New Zealand.

The company has taken delivery of a 17-t payload Sandvik LH517i underground loader (pictured), Sandvik Mining and Rock Solutions confirmed.

A Sandvik TH551i truck and DD421 development drill will also be delivered this year as Macraes prepares to extend its mine life to 2028, the mining OEM said.

The LH517i is a matching pair with the Sandvik TH551i truck. It features the Sandvik Intelligent Control System and My Sandvik Digital Services Knowledge Box™ on-board hardware as standard.

In December, OceanaGold received approval to extend the mine life of the Macraes operation to 2028. This is expected to involve the development of the Golden Point Underground Mine, the Deepdell North Stage III open-pit extension, and the Frasers West expansion.

These projects are forecasted to produce 1.1 Moz of gold over an eight-year mine life, with open-pit and underground operations expected to produce, on average, 150,000-170,000 oz/y of gold.

De Beers taps Sandvik expertise for Venetia underground diamond mine transition

De Beers Group has ordered 19 units of high-tech equipment from Sandvik Mining and Rock Technology for its Venetia Underground Project (VUP), in South Africa.

According to Simon Andrews, Managing Director at Sandvik Mining and Rock Technology Southern Africa, the company will supply a range of intelligent equipment including LHDs, ADTs, twin-boom drill rigs, roof bolters and cable bolters. Amongst the advanced models are the 17 t LH517i and 21 t LH621i LHDs, 51 t TH551i ADTs, DD422i face drills, DS412i roof bolters and DS422i cable bolters.

Partnership will be the watchword in the technological collaboration between the global diamond leader and mining OEM.

South Africa’s largest diamond mine, Venetia has been mined as an open pit since 1992. De Beers Group is investing circa-$2 billion to start mining underground from 2022, extending the mine’s life beyond 2045. The VUP represents the biggest single investment in South Africa’s diamond industry in decades, according to the company.

Allan Rodel, Project Director of the VUP, says the use of new technology is critical in building the mine of the future and will ensure the safety of its people, as well as create unique employment opportunities.

He adds that the successful implementation of this technology holds the key to further improve the mine’s productivity and cost effectiveness, enabling the quality and accuracy required for precision mining. This will also provide real-time geospatially referenced data that supports digitalisation of processes and provide a wealth of data for analysis and continuous improvement.

The underground mine will use sublevel caving to extract material from its K01 and K02 orebodies. Initially the ore will be hauled to surface using a combination of underground and surface haul trucks. As the operation matures, the hauling systems will transition to an automated truck loop in combination with vertical shafts for steady state production.

Sandvik’s Andrews said: “As important as the equipment itself is, De Beers Group was looking to partner with a company who would support them through the VUP journey. Taking a mine from surface to underground has many challenges, including the change in operational philosophy.”

Andrews highlighted that change management processes are as crucial to success as the capacity and performance of the mining equipment. The implementation of the new technology is seldom a straightforward process, and always requires a collaborative effort.

“The expectation of the customer is for a strong relationship with a technology partner who will help them to apply, develop and fine-tune the systems they need, over a period of time,” he says. “This way, the technology is assured to deliver the safety, efficiency and other positive results that the new mine will demand.”

Andrews believes Sandvik Mining and Rock Technology leads the pack from a technology point of view, having introduced its intelligent i-Series machines to enhance remote operation capability. This advanced range combines automation with data management capacity, aligning with the philosophy that De Beers Group has applied to this world-class operation, which prioritises the safety of its people.

Also included in the package for VUP is the Sandvik OptiMine® control system which enables continuous process management and optimisation, focusing on key areas such as face utilisation and visualisation of the operation in near real time. Using data generated by the i Series machines, OptiMine helps mining operations to achieve the lowest operating costs and highest levels of productivity.

Andrews noted that Sandvik Mining and Rock Technology is not new to the Venetia site, having worked with Venetia’s surface operations for some years, providing tools for drilling as part of a performance contract.

“We’ve been following the VUP with great interest and were ideally placed to contribute as we have extensive South African experience with mining customers in transitioning from opencast to underground,” he said. “This has involved providing equipment, implementing the systems and getting a full operation running with the latest equipment.”

He added: “Sandvik Mining and Rock Technology has successfully completed numerous large and ambitious projects, and it reflects our experience in applying automation technologies from first principles. The learnings from these projects will be seen in the VUP as the mining systems are rolled out. We will take the very latest technology and assist the mine to implement it in an underground environment through a collaborative approach using local skills and supporting it from a local base of expertise.”

He emphasises that the automation will be applied through a phased approach, beginning with manual operation and closely monitoring performance through data analytics. Automation can be gradually introduced with the necessary training and experience, ensuring consistency of operation which is the key to success.

“This will allow costs to be driven steadily lower, using the data from the operation of the fleet to guide the transition to automation,” he says. “We will work with the mine to introduce automation and further data management as work progresses deeper into the mine, and as mine employees become more comfortable with this way of working.”

Sandvik Mining and Rock Technology (soon to be Sandvik Mining and Rock Solutions) is geared to support the trackless systems implemented at the mine through the full lifecycle of the machines by supplying spare parts, tooling and components from an on-site Vendor Managed Inventory stockroom and its other South African based facilities.

Sandvik goes back to Toro legacy for underground load and haul line

Sandvik is reintroducing the Toro™ family name to its underground hard-rock loaders and trucks, with some of its i-series models set for the treatment later this year.

The Toro family name has been recognised by Sandvik underground mining customers for decades and now Sandvik is bringing back the bull, firstly with the large intelligent loaders Toro LH517i and Toro LH621i, it said.

“Toro, ‘the bull’, has traditionally symbolised the strength of Sandvik underground hard-rock loaders and trucks since the first model was introduced in the early 1970s,” Sandvik said. “Even though the family name has not been used for 15 years, it has never disappeared from the thoughts of the company and many of its customers.”

For the new generation of Sandvik loaders and trucks, the Toro stands for safer, stronger and smarter, according to Sandvik.

Wayne Scrivens, VP Product Line, Load and Haul, explained: “Safety is at the forefront of our product design and crucial for those who work in or around our loaders and trucks. We also believe that environmentally-sound solutions and sustainability principles firmly belong with safety.

“Being strong and powerful is at the very heart of the old Toro. To be robust, reliable and productive in the most demanding of conditions is part of our heritage, and we will keep that with us going forward. Being smart involves seamless integration with Sandvik’s AutoMine® and OptiMine® offering, but it is also about innovation and smart design: eg how we arrange maintenance access, improve efficiency and reduce waste. Developing intelligence on all frontiers is, and will be, one of the key elements of the Toro going forward.”

The large intelligent loaders Toro LH517i and Toro LH621i now come with several design upgrades aimed to further boost productivity, reduce total cost of ownership and improve operator experience, Sandvik said.

Both loaders can now be equipped with a Stage V engine, meeting the most stringent current emission regulations. Operator speed assist, a new feature that will be available with the Stage V engine option, specifically supports downhill tramming and preserves the equipment brakes as the Sandvik Intelligent Control System can be set to limit maximum speed, the company said.
A new traction control system, available as an option, reduces wheel spin and slippage when penetrating the muck pile, extending tyre lifetime.

Finally, a Digital Trainer training simulator has been added to the load and haul equipment range, offering a compact and flexible solution for the safe training of operators, with authentic controls and real loader control system, Sandvik said.

As matching pairs for the large loaders, the 51 t Toro TH551i and 63 t Toro TH663i trucks will be among the first equipment models to acquire the Toro family name.

Both trucks have recently benefitted from several significant design upgrades including, for example, a new transmission, heavy-duty cooler, AutoMine for Trucks with on-surface navigation possibility and an ongoing Stage V engine trial.

Scrivens said: “Customer feedback on the i-series trucks indicates that overall maintenance costs have decreased compared to their predecessors, the Sandvik TH551 and Sandvik TH663: we have also received the same customer feedback on LH517i and LH621i loaders. Reducing costs in addition to the already-reported positive operator feedback clearly shows we are on the right track, which befits the Toro family.”

The fifth model acquiring the Toro family name is the world’s largest payload capacity underground loader, Toro LH625iE. This features a 25,000 kg payload capacity and is electrically powered by a trailing cable.

The Toro LH625iE loader builds on well-proven technology, but also features the i-series intelligence needed for connectivity and digital solutions, Sandvik said.
