Sandvik Mining and Rock Technology, in an effort to speed up rock drill innovations, has opened a new Rock Drills Innovation Center in Tampere, Finland.

Announced during day one of its Innovation in Mining event this week, the centre will introduce state-of-the-art production and testing facilities for this core Sandvik technology. It will be home to extensive rock knowledge and drilling technology expertise, creating a hub for innovation, the company says. The centre will also complement Sandvik’s existing leading drilling technology competence centre, consisting of an R&D centre, an underground test mine with laboratories, a modern factory environment and university cooperation.

IM put some questions to Timo Laitinen, Vice President of the Rock Drills business unit, to find out more about the €18 million ($21 million) investment.

IM: How will the new innovation centre help the Rock Drills business unit more rapidly develop new products?

TL: We wanted to bring all key functions needed in the development and production of rock drills under one roof. This makes communication between different functions more effective and enhances cross-functional work when developing new products.

Also, as reliability is the most important characteristic in rock drills – and the key feature of Sandvik rock drills – based on our recent customer survey, we increased our durability testing capacity. Now we can do even more endurance testing in a shorter calendar time.

Thirdly, our factory investments speed up prototype production, minimising waiting times between the iteration rounds. All these speed up time to market.

IM: What new technology, expertise, innovation, etc will you be leveraging to speed up the R&D and product development pipeline?

TL: In addition to what I mentioned above, we utilise a Lean & Agile methodology in our R&D with increased customer involvement, transparency and cross-functional cooperation. As Sandvik’s drilling equipment development, as well as digital technology development, happens for the most part here in Tampere at the same site, we can leverage that work for rock drill development too. Digital technology helps read data from Sandvik drilling equipment and service operations around the world, which we utilise to create even better rock drills. Sandvik’s expertise in machining solutions has helped us to integrate advanced quality assurance solutions in our production system. This generates valuable information for rock drill research and development.

IM: Will the Rock Drills business unit have a designated area of the Tampere Test Mine to test prototypes? Was the division previously using the existing test mine facilities?

TL: We have always had a certain designated area in our test mine for rock drill testing. With this investment program for the Rock Drills Innovation Center, we did build a new area in the test mine for this purpose with increased safety and functionality, more capacity and more space.

IM: In terms of R&D, what areas will the innovation centre focus on? What problems/challenges are your customers continuously talking about that you hope to address with this new facility?

TL: Drilling the holes for explosives comes first in the drill & blast production cycle, followed by the other phases of the cycle. Therefore, it was not a surprise to us when the customer survey result was that ‘reliability’ was the most important feature of a rock drill; followed by productivity and operating cost per metre. In addition to further developing these features in Sandvik rock drills, digital technology is sneaking into our rock drills. Our Rock Pulse technology is a prime example of new technology, which helps our customers drill more, better and at lower cost.

IMDEX’s Blast DOG™ technology is gaining recognition, with the drill and blast innovation winning a Queensland mining award last week.

IMDEX Blast DOG, being developed in collaboration with Universal Field Robots (UFR) and tested at Anglo American’s Dawson coal mine in Queensland, won the Greyhound Innovation (METS) Award at the 2020 Queensland Mining Awards.

A semi-autonomously deployed system for logging material properties and blast hole characteristics at high spatial density across the bench and mine, IMDEX Blast DOG™ is commodity agnostic. It is a semi-autonomous system that helps optimise blasting based on high-resolution three-dimensional material models built from sensor data. It is aimed at helping miners get predictable fragmentation and determine ore and waste boundaries, and control vibration, dust, fumes and heave, the company says.

“No other technology has the capacity to produce the same data and provide as large an impact on downstream processes including enhancing productivity,” IMDEX said.

The judges said UFR and IMDEX conquered the challenge of logging blast holes, while removing operators from harm’s way.

IMDEX Chief Executive Officer, Paul House, said: “To be the winner among such esteemed competition is a testament to the team and our collaboration partners, Universal Field Robots, Anglo American, Teck Resources Ltd and Orica, supported by METS Ignited.

“IMDEX has a passion to provide the mining industry with purpose-built solutions. IMDEX Blast DOG is no exception and we are investing heavily in solutions that provide significant benefit to our customers.”

The IMDEX Blast DOG solution moved from concept to prototype in just four months which provided the platform and justification to develop a commercial version, IMDEX says.

The innovation category was hotly debated, with judges looking at all five finalists as addressing the industry’s big issues. This included Emesent’s Hovermap drone payload for “mapping the inaccessible”, Polymathian – “Transforming Mining Value Chains with Industrial Mathematics”, Redeye Apps – “Optimising O&M Inspections – The Redeye Digital Twin” and Sedgman – “SMART Condition Monitoring”.

Coal technology, Mine operation news, Mining services, , , , , , , , ,

CIMIC Group’s Thiess has been awarded a contract extension by Glencore to provide mining services at the Mount Owen coal operation in the Hunter Valley of New South Wales, Australia.

The 18-month contract extension, to commence in July 2021, will generate revenue of A$340 million ($240 million) to Thiess.

Thiess will continue to provide mine planning, design and execution, drill and blast, overburden removal and coal mining services at the mine, it said.

The global mining services provider has operated at Mount Owen since 1994, applying, it says, industry best practice mining operations, with uncompromising environmental and safety standards. It is Thiess’ largest coal mining operation in New South Wales, processing up to 15 Mt/y of run of mine, of which 7.8 Mt/y is mined by Thiess from the Mount Owen North Pit.

Thiess Managing Director, Douglas Thompson, said: “For more than 25 years we have delivered industry-leading, specialised mining techniques at Mount Owen, leading to higher resource recovery, increased plant efficiency and reliable material movement for our client.

“Our team looks forward to continuing our long association with Glencore and the Hunter Valley community.”

Thiess says it has a strong presence in the Hunter Valley where it provides mining services at three mines. It works to deliver social benefits through local employment and training, local procurement, community engagement and Indigenous affairs.

Maptek brings fragmentation analysis option to PointStudio 2020

Comminution of minerals, Explosives and blasting, IoT, Mineral processing, Mining services, Mining software, , , , , , , , , ,

A powerful fragmentation analysis tool is a highlight of Maptek’s new PointStudio 2020 geospatial modelling and reporting software.

Better understanding of fragmentation can account for downstream cost efficiencies, with implications for many aspects of an operation, according to Group Product Manager Mine Measurement, Jason Richards.

“Sub-optimal fragmentation is immediately associated with inefficient excavation and haulage,” Richards said. “Undue damage to crusher parts is another impact. Excessive energy usage, crusher downtime due to wear and tear outside of planned maintenance and delivering out-of-specification product are directly linked to operational performance.”

PointStudio Fragmentation Analysis, released to customers this week, allows key performance indicators to be achieved consistently, Maptek says.

Individual rocks can be modelled from scanning of muck piles and draw points to provide accurate fragmentation S-curves from blasting or caving operations.

The new tool allows blast engineers and surveyors to quickly assess the condition of blasted rock, ideally before the material heads to the crushing process, while oversize rocks can be isolated for more effective haulage and processing, the company says.

“A simple scan-analyse-report workflow provides a table where rocks outside of spec can be identified and dealt with before the material gets anywhere near the plant,” Richards said. “A unique feature allows editing rocks or fines in the 3D view and characterising any that are not correctly defined.”

Visual and tabular reporting is immediately understandable so rock can be fed with optimal dimensions for crushing, according to the company.

Fragmentation analysis on 3D data is considerably more powerful and intuitive than methods that rely on analysing imagery. For operations with Maptek BlastLogic, the digital output can be used to compare actual with predictive fragmentation for continuous improvement of drill and blast processes.

While Fragmentation Analysis is a paid add-on in PointStudio 2020, many other new and enhanced features will be delivered to existing customers for free in the update, Maptek says.

One of the new options allows field surveyors using R3 laser scanners to complete scan registration immediately after scanning has finished.

“We’ve made it possible for fully registered scans to be imported from the scanner controller tablet into PointStudio,” Richards said. “Subsequent scans can then be registered with a single click as they are acquired.”

Surveyors can immediately start interrogation, analysis and modelling in PointStudio. An additional benefit derives from field access to aligned scans, allowing timely checks for survey coverage before moving to the next position.

Mine operations commit significant effort to the capture and measurement of as-built data for working faces and stockpiles, Maptek says.

“They can’t afford to let data inaccuracy and inefficient processing prevent them from getting full value from their survey data,” Richards added. “Bad data can lead to poor productivity and risks bad decisions based on incomplete information.”

Dynamic Drill and Blast Holdings is to carry out drill and blast services at Rio Tinto’s Western Turner Syncline 2 project in Western Australia after entering a services contract with WBHO Infrastructure Pty Ltd (WBHO-I).

Under the contract at the bulk earthworks project, Dynamic Drill and Blast is expected to commence delivery of services immediately until late October. This timeline is dependant on drill and blast volumes required as the project progresses, it noted.

This newly awarded project follows on from current services being undertaken by DDB at the Western Turner Syncline Northern Access Road project, the ASX-listed company said. The company will mobilise two drill rigs, 15 personnel and ancillary equipment to deliver the required services, all of which are contracted on standard terms and conditions for a short-term pact of this nature, it said.

Back in November 2019, Rio said it would invest $749 million in the Western Turner Syncline Phase 2 (WTS2) mine at its Greater Tom Price operations, in the Pilbara of Western Australia, facilitating mining of existing and new deposits and including construction of a new crusher as well as a 13 km conveyor.

On top of this work at WTS2, Dynamic Drill and Blast is currently deploying equipment and personnel to two short term, strategic projects, it said.

“Whilst these contracts are not considered to be material contracts by Dynamic Drill and Blast, they have the potential to evolve into further opportunities in the gold and/or iron ore production sectors,” the company said.

It estimates the revenue generated from the three short-term combined projects will be around A$1-A$3 million ($738,004-$2.21 million). This is based on the fixed and variable nature of these types of agreements, the company explained.

Dynamic Drill and Blast continues to source suitable drill rigs to increase the capacity of the fleet, it said.

Since listing on the ASX earlier this month, three additional Epiroc T45 drill rigs have been sourced to complement the company’s existing fleet, it said. One unit has been mobilised to the Pilbara region of Western Australia, with another two units being transported from North America currently. These drills support the existing asset strategy and are suitable for projects within the tendered pipeline, it said.

And, with DDB’s current workshop facility lease maturing, a new fit for purpose premises including workshop, laydown, and office facilities, has been secured in Wangara, Western Australia, it said.

“The new facility provides greater maintenance and supply chain capacity, and this is now the company’s principal place of business,” Dynamic Drill and Blast said.

OceanaGold’s Haile mine steps up drilling productivity with Epiroc BenchREMOTE

The drill and blast team at OceanaGold’s Haile gold mine, in South Carolina, recently added remote technology from Epiroc to its blasthole drilling process.

Haile is the first gold mine in the US to use Epiroc’s BenchREMOTE technology for remote control drilling with two of its three Epiroc drills, according to the miner.

“This technology provides many advantages for Haile’s workforce – no strangers to working in sometimes harsh South Carolina environmental conditions of extreme heat, wind, and rain,” the company said.

The BenchREMOTE system enables operators to work from a safe distance in a comfortable environment, handling up to three rigs in parallel. This technology allows the operator station to be placed up to 100 m away and +/- 30 m in elevation with a line of sight to communicate with the drills. Haile purchased two Epiroc D65 drills, BD7 and BD8, in 2019 compatible with this new technology.

“The BenchREMOTE package includes the operator station only, so installation design is determined at the operator’s discretion allowing for a customisable end product,” the company said.

Haile Drill and Blast General Supervisor, Aaron Kash, worked with ATC Trailers to design Haile’s housing, building the remote station into a fully insulated enclosed trailer.

“When we bought the equipment from Epiroc, I reached out to our local ATC trailer dealer and had them bring up the specs of a similar trailer,” Kash said. “We made a few changes – making it a little longer, equipping it with a bigger A/C unit to withstand the heat, and upgraded the generator.”

Safety is a primary concern any time people are present on a drill pattern with remotely operated drills. Communication, situational awareness, preparation, and warning systems are necessary for maintaining safe operation, according to the miner.

“Perhaps the most significant benefit of the remote drills is the potential for increased productivity,” the miner said. “Now one driller can operate up to three machines at a time, increasing utilisation.”

Another safety benefit is that the remote drill can access areas that may be unsuitable for people to access.

“With the development of the new Haile Pit, we are encountering historic workings,” Kash said. “We may want to drill into an area with little cover to see what’s there, but we don’t want to risk putting somebody physically in the drill.”

In 2020, the Haile gold mine is expected to produce between 180,000-190,000 oz of gold.

IMDEX continued to advance testing of its BLASTDOG™ technology for drill and blast applications in the June quarter, with another two test sites near Brisbane, Queensland, established.

The company said it also accelerated progress with automated data and visualisation elements of the technology.

In an update almost a year ago, the company said it had carried out successful trials in Nevada, USA, and in Queensland, Australia, while it had additional trials planned in Chile and Australia in the first half of 2020.

BLASTDOG is a semi-autonomous system that helps optimise blasting based on high-resolution three-dimensional material models built from sensor data. It is aimed at helping miners get predictable fragmentation and determine ore and waste boundaries, and control vibration, dust, fumes and heave, the company says.

IMDEX is pursuing these developments as part of a METS Ignited project with Orica, Anglo American and Teck Resources.

Details of the latest BLASTDOG advancements came at the same time as the company released its 2020 financial year results.

These results showed off A$237.7 million ($171 million) of revenue for the year – with a record year-to-date revenue for the nine months ending March 31, 2020 – and EBITDA of $54.4 million.

The company said it had also seen an encouraging start to the 2020 financial year, with improving rental fleet numbers and continued strong industry fundamentals underpinning its growth.

Back in July, the company agreed to acquisition of AusSpec, an industry leader in automated mineralogy to the mining sector, in an A$8.5 million cash and shares deal.

Contract miner MACA has been given an extension to its contract at Ramelius Resources’ Mt Magnet gold mine, with the ASX-listed company set to continue providing mining services at the Western Australia operation for another three years.

The project extension will consist of open-pit mining services including drilling and blasting, and loading and hauling, MACA said.

It is expected the project extension will generate approximately A$130 million ($93 million) in revenue for MACA over the three-year term.

MACA says its total work in hand position now stands at a healthy A$2.3 billion.

Mike Sutton, MACA CEO and Managing Director, said: “We are pleased to continue our relationship with Ramelius Resources at Mt Magnet for a further three years. The services we provide at Mt Magnet and Edna May for Ramelius make up an important part of MACA’s work in hand in the gold sector.”

Orica on the right Track with new digital blasting solutions

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.”
