Sandvik receives record AutoMine order from Codelco’s El Teniente mine

Sandvik Mining and Rock Solutions says it has received a major order for the AutoMine® load and haul automation system valued at about SEK 250 million ($28 million) from Chile’s Codelco to be used in the El Teniente mine.

In addition, a connected load and haul equipment order, with an initial value of SEK 150 million, was received, bringing the total value of the orders to SEK 400 million, Sandvik said.

The contract will run from 2022 through 2027 at the Andes Norte block cave.

Since the first AutoMine system was commissioned in El Teniente’s Pipa Norte mine in 2004, Sandvik has supplied several intelligent load and haul equipment fleets as well as AutoMine and OptiMine solutions to Codelco mines.

The new order will be supplied in two phases. During 2022 and 2023, Codelco will receive two Toro™ TH663i trucks and two Sandvik LH514 loaders, as well as an AutoMine Fleet system capable of being scaled to support up to 16 machines and AutoMine production area hardware for future expansions over several years.

The first phase of the order, which also includes support contracts for the equipment and AutoMine system, will initially be used by Codelco Andes Norte in a new block caving area in El Teniente that is expected to commence production between mid-2022 and early 2023.

From 2023 through 2027, Sandvik will deliver six more Toro TH663i trucks, six Sandvik LH514 loaders and an additional AutoMine Fleet system.

Emilio Vega, Business Line Manager for Automation, Sales Area Andean & South Cone at Sandvik Mining and Rock Solutions, said: “Codelco selected Sandvik’s solutions based on our proven technology, capable of fulfilling requirements for safety, reliability and productivity. Furthermore, we have competent staff capable of serving and supporting the organisation’s existing systems. This provides value-added services that enable optimised productivity in order to meet the customer’s production performance.”

AutoMine underground for loading and hauling is an automation system for autonomous and tele-remote operation of a wide range of Sandvik loaders and trucks. The scalable solution can provide tele-remote to fully autonomous operation for a single machine or multiple machines, including full fleet automation with automatic mission and traffic control capability, according to Sandvik.

Patricio Apablaza, Vice President Sales South Cone & Andean at Sandvik Mining and Rock Solutions, added: “Codelco’s objective is to continue implementing automation and digitalisation solutions in its mining operations. We have a great opportunity, as a key supplier, to be part of this change by supporting Codelco with high-end technology and providing key support to its operations to help our customer succeed in this journey.”

The AutoMine Fleet system is a highly advanced automation system for a fleet of Sandvik underground loaders and trucks sharing the same automated production area. It provides advanced traffic control capabilities, as well as a wide range of interfaces for infrastructure integration to allow for complex automation applications in challenging environments.

Pablo Gandara, Project Portfolio Manager, El Teniente Mine, explained: “For Codelco and, in particular, for El Teniente mine, it is a goal to continue being the largest underground mine in the world. This purpose also needs to be accompanied by other attributes that are key today to continue being leaders in the mining business, such as safety, environmental sustainability, and productivity.

“Considering all these elements, we have come to the conclusion that to operate our mines we require companies that have the same values, and that is how we came to define that the Sandvik AutoMine product satisfies all our needs. In addition to show best practice of a real partnership is the cooperation that began many years ago between Codelco and Sandvik in the first automated project for El Teniente, which was the Pipa Norte sector in 2004. From there we have built a relationship between two companies, we understand each other very well, and we trust in the joint capacities that we have developed.”

David Hallett, Vice President, Automation at Sandvik Mining and Rock Solutions, said: “We are excited to continue our journey in automation and digitalisation at Codelco’s El Teniente mine to help increase safety and productivity for their operations. This order will be delivered as a turnkey solution composed of all elements of Sandvik Mining and Rock Solutions’ offering for equipment, digital technologies and aftermarket. Sandvik strives to be the number one productivity partner for our customers and this order and delivery will embody all elements of this.”

Back in February 2021, Sandvik said it would deliver its AutoMine Fleet system to automate a new fleet of Sandvik LHDs running at Codelco’s Pacifico Superior and Pilar Norte GTI operations, part of the El Teniente underground mine.

Sandvik bolsters Toro LHD line up with LH515i

Sandvik Mining and Rock Solutions says it is launching a new, higher-capacity 15-t size class loader as a next generation model for the current 14-t Sandvik LH514.

The 15-t Toro™ LH515i has one tonne greater capacity than its predecessor, yet it is designed to operate within the same footprint. This new member of the Toro family has been redesigned from the ground up, leveraging all of the benefits of its predecessor, while improving the design based on customer feedback, according to the company.

The new loader has been designed following the principles of intelligence and simplicity, Sandvik says. The Toro LH515i features a totally new Sandvik intelligent control system with 12-in touchscreen colour display, making loader health monitoring easy, providing quick access to data and enabling new solutions for efficient troubleshooting, the company says.

“With a multitude of smart technologies and optimised for use with Sandvik’s AutoMine® and OptiMine® systems, Toro LH515i brings digitalisation to the operator’s fingertips, enabling optimal productivity,” Sandvik says. “To ensure quick and efficient maintenance, the loader features easy access to service points, roomy component layout organised to facilitate servicing and excellent access to systems, both in the cabin and on top of the equipment.”

The loader features an entirely new cabin designed to provide an ergonomic working environment for operators during long shifts, including increased leg space, new seat and dashboard and improved visibility over the extremely flat rear frame of the loader.

The Toro LH515i is available with two different engine configurations from Volvo Penta: the 265 kW Stage V diesel engine, and the 256 kW Tier III engine.

Equipped with selective catalytic reduction exhaust gas technology and a new diesel particulate filter, the Stage V configuration meets very stringent emission regulations. To further help to reduce their greenhouse gas footprint, both versions of engines are fully compatible with paraffinic diesel fuels meeting the EN 15940 standard, Sandvik says.

The launch of the new loader is part of Sandvik celebrating the 50-year journey of Toro loaders and trucks.

Gold Fields looks for South Deep productivity boost with teleremote loading project

As part of plans to establish a sustainable footing for its South Deep mine in South Africa, Gold Fields is trialling teleremote loading in a project with automation specialist RCT.

Gold Fields’ problems at South Deep have been well documented, with the company, in 2018, launching a restructuring plan involving the reduction of mining areas, the lowering of overhead costs and an aim to use fewer machines more productively. This followed significant amounts of investment and continued underperformance at the mine.

It is the latter productivity goal that has led the company down the teleremote loading path.

In the June quarter of 2019, Gold Fields commenced non-line of site remote loading training at South Deep. Phase one of the project was to locate the operator control station in close proximity to the underground loading site, according to the company.

Martin Preece, Executive Vice-President Gold Fields South Africa, said soon after this training started, operators suggested an almost immediate move to “Phase 2” with an operator control station located in a recently built surface control centre in the main building at South Deep.

A surface automation chair was ordered from RCT, installed and commissioned in the centre and the company started the process of training up operators.

RCT’s ControlMaster® Automation and Control solutions enable companies to automate a single machine, to a fully autonomous fleet, while also offering step changes with teleremote solutions that allow operators to take control of machines from control centres, trailer cabins or mobile stations.

The interoperability of these systems allows for the seamless integration into any mine’s ecosystem, according to RCT.

Preece said Gold Fields’ approach with all technology is to trial with limited application, to develop and prove the technology, followed by rapid roll out.

“We are still in the first phase of the project and are learning and adapting our approach as we progress to perfect the system before broader application,” he said.

This first phase already has the company using one Sandvik LH514 LHD for teleremote loading operations in the long-hole stope loading areas of South Deep during shift changes. As Preece explained, the RCT technology allows for the LHD to tram between loading and dumping locations, and back autonomously with operator intervention only required when loading and tipping the LHD.

RCT has provided the on-board sensor technology, the network infrastructure in the working areas, the safety application and the surface operating chair – the Operation Automation Centre – located in the surface control centre, he said.

The control centre (pictured, left) was designed and established by South Deep and hosts the teleremote LHD operator automation centre, a teleremote rock breaker station, the operations control room, maintenance and production scheduling as well as business reporting functions.

This teleremote loading technology is, essentially, adding loaded tonnes to the operation where there previously was none, coming close to ticking off the ‘use of fewer machines more productively’ criteria Gold Fields previously set out in its turnaround plan. While not explicitly stated by the company, one would expect it helped South Deep achieve a 36% year-on-year boost in long hole stoping volumes mined, to 631,000 t, in 2019. Overall, Gold Fields said the mine produced 222,000 oz of attributable gold last year.

Teleremote rollout?

Preece said the technology it is trialling has been de-risked in the respect that it has been proven in many applications globally, and the company had very clear safety and commercial imperatives for it.

“The success of any change intervention is to ensure that the application becomes an enabler rather than a distraction for our frontline teams,” he said.

“We would like to believe we are close to operational deployment. Most of the initial challenges experienced with the technology itself have been addressed; the underground mining team is taking ownership by addressing the operating conditions. Furthermore, a second round of operator and maintenance training has been conducted.”

While the trial is currently limited to long-hole stope loading in between shift changes, in time, teleremote loading in development and destress areas of the mine could also be possible, Preece said. With plans to equip more machines in 2020, the results could get even better.

“The project business case is based on being able to continue loading over shift changes, so there is further upside when we add in the in-shift productivity gains as well as improvements to the development and destress mining cycles,” he said. “Our approach to expanding the rollout is that it must be self-funding – the value generated by the first deployment must fund the rollout of subsequent deployments.”

The company’s ultimate goal is to be able to operate LHDs continuously for 22 hours a day (the limit the machine can safely operate between refuelling, safety inspections and pre-start inspections, according to Preece), but there is more to achieving this aim than just rolling out teleremote LHDs.

“A pre-requisite for loading during shift changes is to be able to break big rocks in the tipping bins,” Preece said. This is where the successful deployment of teleremote rock breaking, operated from the same surface control centre as the remote LHDs, comes in.

Then there are the interactions with other equipment and, most importantly, people to consider.

“When operating the teleremote machine, the whole area has to be barricaded, isolated and protected by laser barriers, which, if breached, force the machine to stop automatically,” he said. “This will limit the application to areas which we can isolate.”

In areas where personnel are required to perform drilling, supporting, backfilling and other activities, the area cannot be completely isolated and the LHD cannot function optimally, according to Preece.

This might not be the case indefinitely.

“South Deep is exploring opportunities to schedule activities separately to enable broader application,” Preece said.

Similar technology deployed for trucks would be another future area of focus, according to Preece, while he said the mine was also in the early stages of trialling automated long-hole drilling in stopes over shift changes.

South Deep is one of the deepest mines in the world, going to depths close to 3,000 m below surface. Even so, depth is not one of the main business drivers for the increased take up of teleremote operations, according to Preece.

“Safety benefits and the time a machine can effectively be utilised make up for the bulk of the return on investment,” he said. “The challenge with deeper mines are on the support side; if the network infrastructure is in place, it should be the same for shallow or deep mines. For deeper mines, it will take longer to get maintenance and instrumentation support to the machine if something goes wrong.”

Still, could full automation be on the cards?

“Yes! Loading activity remains the most challenging given the variable fragmentation of material,” Preece said. “Operators still need to perform the loading and tipping activities.”

These teleremote and automation projects, on top of personnel and mobile equipment tracking systems previously mentioned in the company’s 2019 annual report, bode well for future automation take up at South Deep, as well as the success of Gold Fields’ turnaround plan for the asset.
