Sandvik showcases digital mining developments in Brisbane

Last week, close to 300 leaders from the mining, construction and quarrying industries from Australia, Japan and Indonesia met in Brisbane, Australia, for a two-day summit, hosted by Sandvik, to showcase best practice examples of digitalisation.

The Digitalization in Mining event, on December 3-4, allowed Sandvik to demonstrate its latest digital offering and introduce participants to the latest innovations across its product portfolio, including process optimisation with OptiMine®, information management through My Sandvik digital services and autonomous operation with AutoMine ̶ together with the latest equipment in underground and surface drilling, loading and hauling, crushing and screening and the rock tools management system.

During the event Sandvik also announced two product launches: AutoMine Access API, which gives mines the power to connect non-Sandvik equipment to AutoMine, and its first Stage V compliant underground loaders for hard-rock mining applications.

Jim Tolley, Vice President, Sales Area Australia Pacific, Sandvik Mining and Rock Technology, said digitalisation is helping companies to grow and optimise their operations. “Our partners were keen to join us at this event because they know that digitalisation has a critical part to play in making their mines sustainable for the future.”

Day one of the event featured speakers from mining companies across Australia, as well as leaders in mining technology, process optimisation and automation. They explained the benefits their organisations have gained by implementing automation and process optimisation solutions, as well as the accompanying change in mindset, according to Sandvik.

The following presentations set the program for the day, followed by a panel discussion:

  • Shaping the Industry Digital Ecosystem (Sandvik);
  • Holistic Perspective, Focusing on Productivity, Safety and Optimised Machine Performance (Byrnecut);
  • Developing the Mine of Tomorrow (Barminco Ltd);
  • Machine Learning  ̶  Keeping it Real with Case Studies from across the Mine Value Chain (PETRA Data Science);
  • Capturing Opportunities for Digital and other Product Technology Solutions (Rio Tinto);
  • Automation Technology to Improve Efficiency and Consistency in Longwall Development Operations (Glencore);
  • Direction of Technology and Automation (Newcrest); and
  • Data Privacy, Rights and Control (Sandvik).

Pat Boniwell, Managing Director, Byrnecut Australia, said the industry will improve productivity, safety and optimise machine performance through a more “fundamental understanding” of the individual processes that make up our operations.

“New technology, automation, data transfer and analysis will all assist us in increasing the utilisation of our resources,” he said. “Data is essential, but if it is not being looked at then we are just gathering data for the sake of it. We need to continue to increase the levels of engagement between all stakeholders.”

He concluded: “We are doomed to failure unless we take our people with us and are prepared to question and be challenged.”

PETRA CEO, Penny Stewart, meanwhile, homed in on machine learning, which, she said, powers “digital twin prediction, simulation and optimisation to increase mine productivity, efficiency and yield, by showing engineers and supervisors how to reproduce their ‘best performance’ 24 hours a day, seven days a week”.

She added: “PETRA’s MAXTA™ Suite digital twin applications provide platform agnostic software-as-service operational decision support across the mine value chain ̶ from resource engineering through to processing plant set point optimisation.”

Day two of the event began with a presentation on sustainability by Henrik Ager (pictured), President, Sandvik Mining and Rock Technology, explaining how critical it is for long-term performance.

“Driving productivity and greenhouse gas efficiency together is going to be key for us at Sandvik, improving productivity and greenhouse gas efficiency will be the best way for us to add value for our customers,” he said. “My view is that the more we link our sustainability targets to normal business targets and find ways to combine them to achieve a common good, the better chance we have to deliver on them.”

Also, during the second day, delegates had the opportunity of a virtual visit to several Sandvik customers, including: Northparkes Mine (Australia), Resolute Mining Syama mine (West Africa), RedBull Powder Company (New Zealand) and Aeris Resources Tritton mine (Australia).

Harry Hardy, General Manager Customer Accounts, Applications Engineering and Marketing, Sandvik Mining and Rock Technology, Sales Area APAC, said the company often gets asked for reference cases and data to illustrate the value and payback of digital solutions. “Over the two days of the conference, our customers were able to share their own experiences and quantitatively demonstrate how our solutions have helped increase their productivity, reduce their production costs and increase their safety.”

Maptek, PETRA Data Science combine mine schedule optimisation and digital twin expertise

In what is claimed to be an industry first, Maptek and PETRA Data Science have established a partnership to enable “seamless value chain optimisation and simulation” from resource models through to metal produced.

This development will allow mining companies, for the first time, to use millions of tonnes of their historical performance and resource metadata for dynamic optimisation, according to the two companies.

PETRA Managing Director, Penny Stewart (pictured, left), said: “I see Maptek as the go-to company for spatial data in mining. Whether you are looking at their 3D virtual environments for geological modelling and mine optimisation, or long-range laser scanners for 3D mapping and monitoring, every aspect is custom built for mining. Any true digital twin in mining needs to consider geology.”

She continued: “Our partnership with Maptek provides PETRA with easy access to upstream geological data for value chain optimisation, and enables Maptek to extend schedule optimisation downstream of the mine. For the first time, miners will be able to play forward the mine schedule into the processing plant.”

Stewart recently visited the Maptek R&D facility in Adelaide, South Australia, where she listened as the Manufacturing Manager explained how in response to customer requests, they have shed 4 kg off the weight of their scanners, she said.

“The custom-built innovations incorporating aerospace technology and military grade specs are really impressive. I mention this example because it illustrates Maptek’s laser focus on their mining customers, and this is strongly aligned with PETRA’s reason for being.”

She concluded: “As a mining engineer, I know that Maptek’s reputation for maintaining substantial investment in software and hardware for spatial data is second to none. I feel honoured that Maptek has chosen to partner with PETRA, and the whole PETRA team is excited by what this partnership will achieve for the mining industry!”

The integrated technology offerings of PETRA and Maptek cover solutions from geological modelling to plant and process optimisation and simulation. The partnership combines deep domain expertise from across the whole value chain and, together, PETRA and Maptek offer the industry a practical alternative to the common practice of siloed optimisation, according to the two companies.

Under the partnership, Maptek Evolution mine schedule optimisation will be dynamically linked to PETRA’s latest digital twin performance models including; metal produced, grade, quality, recovery and throughput. “Dynamic mine scheduling is made possible by bringing together Maptek optimisation engines and PETRA’s prediction and simulation algorithms,” they said.

The agreement will see Maptek BlastLogic blast design optimisation also benefit from dynamic links to PETRA digital twin models for loading, crushing and grinding. In addition, PETRA MAXTA digital twin blast design simulation will benefit from connection to BlastLogic historical drill and blast design data.

Stewart will continue to drive the growth and development of PETRA solutions, with Maptek Managing Director, Peter Johnson (pictured, right), appointed to the PETRA Advisory Board. “PETRA will continue to operate a platform-agnostic business model, with investment funds channelled into further development of PETRA’s open format integrations, including APIs and architecture,” the companies said.

Peter Johnson said Maptek’s goal to enable customers to realise greater value from the available mine data requires consideration of a context far beyond the orebody model and mine plan.

“We need to empower our customers to relate the performance and characteristics of processes and equipment far downstream from geology or planning assumptions and understand the relationships better,” he said.

“PETRA has a proven capability to create prediction and optimisation algorithms for miners through the innovative application of their data science expertise and experience in the real world,” he added.

He concluded: “Our investment and ongoing partnership is all about building business improvement into the mining cycle by leveraging the technology of both companies.”

PETRA’s algorithms are deployed by mining companies around the world, while its MAXTA digital twins for value chain optimisation ingest 10s of millions of tonnes of ore data to predict and simulate plant performance using machine learning. The latter have been successfully used for geometallurgical prediction, drill and blast simulation, and process control simulation and optimisation.

The company recently applied its big data and AI capabilities to an iron ore mine in Western Australia, which, according to PETRA Technical Director, Zeljka Pokrajcic, was able to demonstrate the link between the mineral resource and comminution.
