Orica is looking to set a new benchmark for blast loading designs in Latin America after deploying its Design for Outcome solution in the region.

The company, focused on integrating its digital blasting tools to improve outcomes, is leveraging its BlastIQ digital blast optimisation platform within this new solution, Angus Melbourne, Chief Commercial and Technology Officer of Orica, told delegates at Massmin 2020 last week.

In a presentation titled, ‘Blasting’s Critical Role in Extracting Ore’, Melbourne mentioned Design for Outcome as an example of where the company was delivering integrated digital solutions in Latin America.

“Design for Outcome is an automated continual optimisation solution that sets a new benchmark for blast loading designs,” he said. “It utilises data science to process both upstream and downstream data to automate blast designs. This produces tailored and optimised blast designs by reducing blast variability and explosive consumption while increasing productivity.”

Using machine-learning algorithms, Design for Outcome processes measured-while-drilling data to classify ground hardness throughout each blast hole and then match explosives energy to hardness domains to automatically generate tailored blast loading designs, Melbourne explained.

Through artificial intelligence, these algorithms are trained with the data received from the fleet control systems (FMS) and previous blast results. This enables final automation of the blasting design process and its execution in the field with Orica’s smart control systems and programming interfaces, loading the blast accurately according to the generated design. These elements combine to ensure the desired outcomes are achieved, Melbourne said.

“Digitally-enabled blasting solutions such as Design for Outcome are allowing us to work with customers in different ways, to think and act differently and expand our role in the mining value chain,” he said.

Such a solution is part of the company’s plans to automate its segment of the mining process. This goal was strengthened last month with the launch of the Orica and Epiroc jointly developed Avatel™ semi-automated explosives delivery system.

A key enabling technology of Avatel, which is built on the foundation of Epiroc’s Boomer M2 carrier, and Orica’s automation vision is WebGen™, the company’s fully wireless initiation system. When combined with Orica’s LOADPlus™ smart control system, specifically designed on-board storage, assembly, digital encoding capability and Subtek™ Control bulk emulsion, Avatel provides customers with complete and repeatable control over blast energy from design through to execution, Orica says.

While referencing the second key pillar in Orica’s digital strategy, Melbourne highlighted the use of the company’s Bulkmaster™ 7 smart, connected explosives delivery system in Latin America during the virtual event.

The new delivery systems not only improve productivity but begin to digitise critical workflows between design and execution in drill and blast operations, according to Melbourne.

The Antamina copper mine in Peru, a joint venture between BHP, Glencore, Teck and Mitsubishi, will soon be leveraging such a system, with Melbourne confirming seven Bulkmaster 7 units had been shipped to the mine and were undergoing commissioning.

Orica’s third digitalisation pillar is the measurement of downstream impacts of the drill and blast process, which is where FRAGTrack™, the company’s automated rock fragmentation measurement device comes into play.

This device captures, analyses and reports real-time data for optimising blast operations, improving downstream productivity and tracking overall operational performance in mining and quarrying, Melbourne explained.

This system is active across several key customer sites in Latin America, with Teck’s Carmen de Andacollo operation in Chile being one of the first to adopt the technology in the world, according to Melbourne. He said the copper operation is using the insights to deliver efficiencies across the value chain through digitally enabled optimised blasting.

Orica’s suite of rock movement, blast fragmentation and digital blast optimisation solutions have been gaining traction of late, with miners across the globe employing or trialling the products as they look to improve mine site performance.

Ahead of the annual Explosives and Blasting feature (to be published in the International Mining July/August 2020 issue), IM spoke with Rajkumar Mathiravedu, Vice President of Digital Solutions at Orica, to get an update on progress with the company’s digital solutions.

Back in Orica’s 2019 full-year results, Orica mentioned it had secured its first customers in Latin America for its ORETrack™ solution, which provides RFID-based tracking of rock movement from blasting operations.

Mathiravedu said these first adopters were recognising the value delivered by the technology, with ORETrack working well in the initial applications.

“We are also continuing to co-develop and expand our ORETrack technology in collaboration with customers in Latin America, with additional customers adopting the ore tracking capability,” he said.

“Further trials are also planned for the near future, including locations in Australia and North America.”

The number of customers taking up Orica’s FRAGTrack™ solution, which provides blast fragmentation data with auto-analysis capability, meanwhile, has been growing in the face of COVID-19 travel restrictions.

Orica carried out its first fully remote installation of FRAGTrack during lockdown in Australia, with a second in Finland and a third one completed in North America recently.

Mathiravedu said a key focus in developing the solution, which captures real-time fragmentation measurement data for downstream unit productivity improvement and tracking of operational performance, was ensuring it was “a plug and play solution” that could be installed and supported remotely.

“We developed rigorous training material and installation instructions and married these with real-time augmented reality capability to remotely guide and support our customers through the implementation,” he said.

“We have found this particularly advantageous during the COVID-19 restrictions, but also this allows our customers to manage the implementation timing to suit their operations.”

An example of this could be the desire for a customer to install FRAGTrack when the shovels are down for maintenance, without having to wait for an Orica specialist to come to the site and install the system.

Reflecting on the recent remote installation achievements, Mathiravedu said: “This proves we have a successful remote release model that customers are valuing during these unprecedented times.”

BlastIQ workflow integration

Fifteen months after the release of its next generation BlastIQ, Orica has now surpassed the 60-site implementation mark of its digital blast optimisation platform.

Mathiravedu said BlastIQ and the company’s ever-growing digital capabilities are designed to improve blast outcomes by integrating insights from digitally connected technologies at every stage of the drill and blast process to drive continuous improvements for its customers.

“Focusing on the needs of our surface mining customers, we have been able to deliver the benefits of cloud-based technology, providing convenience and flexibility for customers to access their blasting data online anywhere, anytime from any device,” he said.

“Customers are also benefitting significantly from digitising their blasting workflows, delivering efficiencies and improved quality control across their blasting operations, resulting in greater visibility of blast inputs and outputs in real time while benefiting from better blast outcomes.”

As an open, secure, and connected digital platform, BlastIQ’s blast-related data is being integrated directly into customers’ mining value chain and remote operation centres via secure cloud-based APIs, Mathiravedu said.

“This is enabling customers to drive better mine-level decisions based on data integrations between our platform and theirs, creating a stronger bond between planning, drilling, blasting, load and haul and processing operations at the site,” he said.

BlastIQ is an inter-operable platform and is being delivered as a Software as a Service product to customers, meaning they receive new functionality, value and features as soon as they are developed, according to Mathiravedu.

“Enhancements are scheduled and developed based on direct feedback and submissions from our customers all around the world to ensure the product evolves to meet the discrete needs of their operations,” he said.

Outside of BlastIQ specifically, Orica has started to deliver digital optimisation services to its customers, according to Mathiravedu.

“State-of-the-art” digital products and advanced data science and analytics, combined with blasting technical know-how and market-leading blasting technologies, enables customers to cover whole of value chain solutions, enabled by blasting, Mathiravedu said.

“Also, using a series of industry 4.0 smart Internet of Things sensors and Edge computing to replace inefficient manual processes, measurement data can be used in real time to improve future mining outcomes based on data science, analytics and machine-learning algorithms to drive continuous improvement of the entire mining value chain.”
