Gold Fields will soon begin an autonomous truck trial at its Granny Smith underground mine in Western Australia, leveraging the robotic smarts of Universal Field Robots (UFR) and an existing Epiroc Minetruck MT65 it has within its fleet.

In the company’s recently released annual results, Gold Fields stated it was developing its first underground automated truck, ready for trials at Granny Smith in the second half of this year.

Later, the company told IM that this project involved Brisbane-based UFR, with the machine in question having already received the custom paint job (see photo above).

The purpose of this trial is to validate autonomous truck haulage over shift change when the mine is evacuated for blasting, the company said in its annual results, with Rob Derries, Unit Manager: Innovation & Technology at Gold Fields Australia, confirming the truck will initially be tested and validated in a separate area underground at Granny Smith.

“Once validated, we will be operating the automated truck on the main decline over shift change when the mine is normally evacuated for blasting activities, enabling further material haulage in time where activities are normally halted,” he told IM.

The initial truck pilot is expected to continue for up to 12 months with plans to retrofit further trucks in the Granny Smith fleet to operate autonomously over shift change after validation of this initial pilot.

Gold Fields says it is investigating and partnering to develop a number of automation solutions to ensure the safety of its people while also enabling increased productivity.

Derries said: “This trial aligns with Gold Fields’ approach to adopting agnostic technology and automation solutions. In the future, this technology can be adopted on a number of different machine manufactures and types and will integrate with existing teleremote guidance LHDs and Mine Operating Systems.”

UFR, for its part, has been involved in the development of several automation projects within mining, including BLAST DOG™ blasthole sensing and physical measurement technology – in collaboration with IMDEX – and a robotic application for zero-entry work on underground production blastholes – a project it is working on with METS Ignited and several mining companies, including Gold Fields.

Granny Smith produced 288,000 oz of gold at an all-in cost of $1,171/oz in 2022. It is currently mining four lenses from the Wallaby orebody (Z70, Z80, Z90 and Z100), accessed from a single decline. Mining administration and maintenance is located at the Wallaby mine, while ore is processed at the Granny Smith carbon-in-pulp processing plant, 15 km east of the Wallaby underground mine, under campaign milling conditions.

Back in October 2022, Epiroc confirmed an order from Gold Fields for a fleet of 65-t payload Epiroc Minetruck MT65 underground haul trucks with automation features to be used at Granny Smith.

IMDEX’s Lawie on BLAST DOG’s continual orebody knowledge evolution

In a presentation to the International Mining and Resources Conference (IMARC) in Sydney, Australia, today, entitled ‘Get a Dog’, IMDEX Chief Geoscientist and Chief Technologist – Mining, Dave Lawie, charted the five-year development journey of the company’s BLAST DOG™ technology that, the company says, provides unrivalled pre-blast orebody knowledge and a 3D view into the bench.

BLAST DOG is a commodity-agnostic blast hole sensing and physical measurement technology that will provide near real-time blast hole physicals and orebody knowledge, according to IMDEX. The value of the technology is in the power of integrated data, enabling experts to make informed decisions that affect each stage of the mining value chain.

“Ten years ago, orebody knowledge was quite an abstract notion,” Dr Lawie said. “When we first discussed it, people wanted more information. Five years ago, they were becoming more interested, and today it’s a theme in the industry.

“IMDEX has led that discussion and been at the forefront of the development of technologies that deliver better orebody knowledge. Reliable orebody knowledge is central to good mine planning. It provides the data that allows for informed decision making that delivers savings throughout the mining life cycle.”

The BLAST DOG sensor is on a track-mounted robotic platform with semi-autonomous hole positioning and alignment capability working over variable terrain and bench conditions, IMDEX explained.

Directly and rapidly measuring the orebody via blast holes reveals what the ore reserve looks like in the ground, at a high resolution, and immediately prior to its extraction, providing mining companies with “insurance” data that protects people, heritage, equipment and neighbouring communities, according to the company.

The data has the potential to be used to develop programs to, the company says, improve safety; mine planning; blast design; fragmentation; reduce fume, flyrock, vibration, air-blast and dust; and improve material assignment post blast.

Dr Lawie said an IMARC presentation in 2015 discussing spatial factors among the activity drivers in mining confirmed to IMDEX that its identification and focus on orebody knowledge was correct. But at the time there was no “Internet of Geosensing” system able to deliver the right information.

“The reference to spatial factors is really the Internet of Geosensing; IoG is an orebody knowledge system, and that’s what BLAST DOG delivers,” he said.

The reduction or management of variation alone creates value, with the characterisation of waste as important as the identification of the target metals or minerals, according to IMDEX.

It creates the opportunity for better segregation of ore from waste during mining and, therefore, grade optimisation as well as maximisation of ore recovery and minimisation of dilution.

With the delivery vehicle coming from Universal Field Robots and the downhole sensors designed and refined by IMDEX, the addition of MinePortal 3D visualisation software has accelerated IMDEX BLAST DOG for mining production, IMDEX says.

The company achieved its first commercial contract with BLAST DOG in August this year, at Iron Bridge in the Pilbara region of Western Australia, with the agreement providing for the staged use of up to three units together with associated products, software, data analysis, reporting and support.

Six commercial prototype trials are planned for the 2023 financial year under the first phase of BLAST DOG development.

IMDEX concluded: “The BLAST DOG technology will continue to evolve, with new answer products, novel and democratised modelling and visual outputs being developed along with expansion to other commodities and geographies and eventually to underground applications.”

IMDEX has announced what it says is a “major milestone” for its BLASTDOG™ drill and blast technology.

IMDEX BLASTDOG is a semi-autonomously deployed system for logging material properties and blasthole characteristics at high spatial density across the bench and mine and is commodity agnostic, according to the company. It has been developed in collaboration with Universal Field Robots and tested at mines in Queensland, Western Australia, Chile and Nevada (USA).

At an industry event today, IMDEX said BLASTDOG would move from engineering development to commercial prototype by the end of the year.

Progress was outlined to representatives from development partners from METS Ignited, as well as other mining sector executives.

IMDEX said there is already strong industry interest in BLASTDOG because of its capacity to deliver reliable, real-time data that will enable critical mine planning decisions to be made earlier, introducing greater efficiencies throughout the mining value chain.

IMDEX Chief Executive Officer, Paul House, said no other technology had the capacity to produce the same data and provide as large an impact on downstream processes, including enhancing productivity.

“It has the capacity to improve productivity, efficiency, and safety and is part of IMDEX’s internet of geosensing initiative, and will significantly increase mine to mill efficiency,” House said. “Moving to a commercial prototype is a significant development. We will work with prospective clients to ensure that when it is released IMDEX BLASTDOG will deliver the results, efficiencies, and safety that will be its trademark.”

Among the benefits of IMDEX BLASTDOG outlined by the company are the ability to:

  • Improve fragmentation;
  • Improve material and grade control;
  • Reduce geotechnical risk;
  • Reduce adverse vibrations;
  • Define ore boundaries and prevent ore waste;
  • Indicate reactive ground; and
  • Reduce fume, fly rock and vibration

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”.
