GroundProbe and Orica collaborate on ‘world-first’ BlastVision solution

GroundProbe, a member of the Orica Group, has launched BlastVision®, a world-first solution that, it says, delivers actionable blast performance insights for optimal safety and productivity.

The crucial data aids in the detection of potential misfires and out-of-sequence firing and in identifying and tracking fly rock, according to the company. Intra-blast monitoring also adds valuable wall control insights, such as monitoring and mapping instantaneous blast damage to slopes and identifying movement on significant structures.

GroundProbe, a specialist in geotechnical monitoring, leveraged the partnership with Orica, a leading mining and blasting solutions provider, to gain information around current blast monitoring methods through interviews with engineers, according to GroundProbe CEO, David Noon.

“Through talking to mine site engineers responsible for blasting on the ground, we identified that many sites were still using quite simple and sometimes unsafe methods for blast analysis.

“Techniques included recording blasts with ground-based camera systems and conducting visual inspections of this footage to determine areas of concern.

“From this, the idea of using drone footage and automated algorithms to quickly identify key areas of interest was born.”

BlastVision takes custom high-speed drone footage of a blast as it happens, using world-first advanced proprietary algorithms and modern AI frameworks to convert the footage into analytics data, according to GroundProbe. Data is then remotely analysed in its custom software platform, with insights swiftly reported back to the site. From these insights, mine site personnel can optimise blasting and monitor the impacts of blasting, improving both safety and productivity, the company said.

The solution has been tested, trialled or demonstrated across over 60 mine sites around the globe, positively impacting hundreds of drill and blast team members across these mine sites, according to GroundProbe.

GroundProbe’s VP – Technology, Fernanda Carrea, said that no other solution provides the range of insights from the whole blast area that BlastVision provides, from start to finish.

“BlastVision provides an increased level of safety, efficiency, accuracy and productivity through our software algorithm automatically identifying key areas and issues,” Carrea said.

“Data is also able to be captured before, during and after a blast, and covers the blast area in its entirety.

“We can proudly say that this patent-pending technology is a world first.”

Orica ups the fragmentation monitoring ante with FRAGTrack Gantry

Orica has announced the release of what it says is its most innovative fragmentation monitoring solution yet, FRAGTrack™ Gantry.

The company calls FRAGTrack Gantry a market-first haul truck measurement solution that combines real-time oversize detection alerts and accurate particle size distribution (PSD) of fragmentation on all models and sizes of haul trucks.

The new product combines the success of the existing suite of automated post-blast fragmentation monitoring solutions – covering the original FRAGTrack release and the release of FRAGTrack Crusher earlier this year – and the feedback from customers experiencing loss of production due to crusher blockage.

FRAGTrack Gantry uses advanced machine vision and machine learning technologies to enable autonomous triggering and processing, without interfering with the haulage operation, Orica claims

It leverages real-time oversized detection through artificial intelligence (AI), with the machine-learning capability applied to real-time detection accomplished within seconds, with alerts syndicated via Fleet Management Systems (FMS), email or SMS for the re-routing of trucks. Operators can also predetermine customisable oversize limits, enabling a reduction in crusher blockage/damage frequency due to oversize material, the company says.

Orica Vice President – Digital Solutions, Raj Mathiravedu, said: “The full adoption of AI technology into our architecture, coupled with our strategic partnership with Microsoft, allows us to expedite the delivery of capabilities that were not previously possible, and FRAGTrack Gantry is another example of how we are leveraging AI to help deliver intelligence and value to our customers.”

The reliable and accurate fragmentation information from FRAGTrack Gantry enables customers to optimise their drill and blast operations for downstream processes without impacting the haul circuit operation, Orica says. The addition of a Gantry option complements the suite of FRAGTrack measurement systems currently available for shovel-, crusher- and conveyor-mounted configurations.

Sandvik introduces new tophammer drill rig for drill and blast contractors

Sandvik Mining and Rock Solutions is launching what it says is a new, even more productive and sustainable top hammer drill rig, designed especially for drilling and blasting contractors.

The redesigned Dino™ DC420Ri will replace its predecessor, the Dino DC410Ri, although the proven overall concept – namely the biggest coverage area in its class and powerful rock drill – will remain, Sandvik says. In addition, the new Dino DC420Ri will feature a wider carrier for improved stability and a Stage V engine for lower emissions, together with a drill rod carousel and one-hole automation for increased productivity.

During the span of just a few years, the Dino DC410Ri top hammer drill rig has become a popular choice for urban contractors and others such as small mine sites and quarries looking for productivity and mobility in the 51–76 mm hole size range, according to Sandvik. The boom system has the largest coverage area in this drill rig category and the powerful 14-kW RD414 rock drill enables high-capacity drilling, it says.

Upgrades were, however, needed to ensure its proven concept remains competitive for years to come, in terms of both productivity and sustainability, Sandvik said.

Several of the key features on the newly-introduced Dino DC420Ri have been completely redesigned. A Stage V diesel engine now provides regulatory compatibility for the markets where this low-emission engine standard is required and the rig carrier is wider, offering better stability – thereby improving operator safety in difficult terrain and at challenging work sites, Sandvik said. The third major upgrade is the actual drilling system, which can now be fitted with an optional three-rod carousel cassette to enable longer holes, up to a depth of 14 m. Future upgrades will add the option of one-hole automation, making full use of the potentially longer holes and improved productivity made possible by the addition of the drill steel carousel.

In addition to the most significant upgrades to the tracked carrier, drilling system and engine, the Dino DC420Ri will also feature several other smaller, but nevertheless significant, new features, Sandvik says.

Operators of the new machine will enjoy a new 7 in (178 mm) touchscreen and a control system and screens with the same look and feel as cabinless Sandvik drill rigs Commando™ DC130Ri and DC300Ri, offering a unified user experience, ease of training and other commonality benefits, the company said. The drill navigation system is updated to the TIMi version and the electric systems have been redesigned to improve overall robustness and reliability.

Over the next few years, the Dino series will be streamlined into a single Dino DC420Ri with two engine options for both Tier 3 and Stage V emission classes, Sandvik says. Until then, the Dino DC410Ri will remain on the market to bridge the offering for those customers requiring a Tier 3 engine. Future system updates will also include an open interface for transferring 3D data to third-party systems for purposes such as drill and blast planning or production control.

Sales of the new Dino DC420Ri have already commenced, with deliveries due to start late 2022, Sandvik added.

IMDEX focuses on drilling fluids, AMC BORE HOLE STABILISER release to boost productivity

IMDEX is talking up the use of drilling fluids as part of its holistic focus on improving drilling performance when out in the field.

The company’s drilling optimisation solutions combine best-in-class technologies, sensors, and motors to deliver improved performances, but, for IMDEX Drilling Optimisation General Manager, Charles Macfadyen, drilling fluids are at the start of the value chain, maximising the data delivered from the company’s technology and tools.

“Costs are always increasing, so the emphasis is on precision drilling: drilling smart metres and drilling efficiently,” Macfadyen said.

“It all relies on fluids to be able to do that. Fluids are an essential part of the drilling process with the potential to unlock hidden productivity when used effectively.”

He says while the oil and gas industry has long understood the importance of fluids and the skills of mud engineers, the understanding within the mineral exploration community has not been as widespread.

“There is a big difference in the cost of exploration drilling between oil and gas, and mineral exploration, but the science and logic will come to mining; the understanding that it’s far more than just a fluid, there’s an understanding of what equates to precision and enhanced performance that makes it special.”

Additional costs caused by higher operational standards, environmental restrictions and increased hole depths will continue – and could be the catalyst for a greater understanding of the part played by fluids, according to IMDEX.

IMDEX has around 100 drilling fluid products to cater for specific regional and global requirements, with the most recent addition being AMC BORE HOLE STABILISER™ (BHS).

BHS is a multifunctional product formulated specifically for air drilling applications, particularly drill and blast applications.

It helps prevent a wide range of down-hole problems including poor collaring, hole decay or sidewall instability, provides a degree of lubrication to the hole and will improve the lifting capacity of the air stream for cuttings transportation, according to the company.

Use of BHS in an underground mine in Western Australia resulted in an increase of up to 40% more metres drilled per day, reduced drilling consumables by up to 50%, improved load times and explosives use for explosive crews, and reduced HSE risks through less manual handling to mobilise and install casing, IMDEX says.

“For drill and blast, the side wall imperative is for both function and efficiency,” Macfadyen said. “BHS delivers improved productivity while using less explosives and less redrills.

“IMDEX drilling fluids are much more than a fluid – you actually get the knowledge that comes not just from making premium fluids and understanding that over more than 30 years, but also the knowledge that comes from our understanding of the drilling market, and of rock knowledge.

“Others don’t have that rock knowledge. It’s the tangible knowledge that at any given moment in time you know what you’re drilling through, the geological understanding, the resource definition, the granular knowledge behind how to optimise your fluids program to cater for that.

“Whether it’s orientation, mineralogy or any geological understanding it’s the essential knowledge that you need to develop a fluid or optimise a drilling program.

“It puts us in a leading position. Unlike others, IMDEX is able to leverage intimate rock knowledge, lab capabilities and global mud engineers to unlock the potential of any drilling program.”

IMDEX’s presence in 70% of major mining operations globally has allowed the company to foster this knowledge, according to Macfayden.

Thiess to deliver mining services to Mount Holland lithium mine JV

Thiess says it has been awarded a four-year contract by Covalent Lithium to deliver mining services at the Mount Holland lithium mine in Western Australia.

Covalent Lithium is a joint venture between Wesfarmers and Sociedad Quimica y Minera de Chile (SQM), one of the world’s largest lithium miners.

Under the contract, Thiess will deliver drill and blast services, mining of overburden and ore, and equipment maintenance with a strong focus on community development and environmental protection, it said. Thiess commenced mobilisation and early mining operations in January.

Thiess Executive Chairman and CEO, Michael Wright, said: “We are very pleased to be selected by Covalent to undertake mining at the Mount Holland mine. This award recognises our team’s ability to deliver sustainable mining solutions and deliver enduring value for our clients across diverse commodities.

“We look forward to working with Covalent Lithium to safely position their operations for optimal efficiency, productivity and cost performance, and contribute strongly to a clean energy future.”

The Mount Holland Mine produces lithium-bearing ore that is concentrated and refined to produce lithium hydroxide, a mineral used to enable electric vehicles and battery-based energy storage systems. EPC contractor, Primero, is currently constructing the Mt Holland concentrator to process ‘run of mine’ ore at a rate of circa-2 Mt/y and produce an output of circa-400,000 t/y of spodumene concentrate to feed the company’s integrated lithium hydroxide conversion refinery situated in Kwinana.

Metarock Group transformation takes shape with new coal contracts

Australia-listed Metarock Group has banked two contract wins this week, one at the Cook Colliery in Queensland and one at the Maxwell underground coal project in New South Wales.

The former has seen its Mastermyne subsidiary become the contract operator at Cook for Constellation Mining, a subsidiary of QCoal Group. The contract term of four years comes with a further two-year option and the company will see work commence immediately under the Mining Services Agreement.

The Cook Colliery was purchased by QCoal in July 2020 and has been maintained under care and maintenance since the acquisition. In July 2021, Mastermyne was selected to carry out a package of work to prepare the mine to re-commence production. This work included recommissioning of existing underground infrastructure, overhauling of mining equipment, establishment of production panels and other associated administrative and procurement works. This first tranche of work has been completed and the mine is now ready to commence production.

Mobilisation underground is already well progressed with the first Joy (Komatsu) miner underground and cutting coal as it forms up the production panels that will see the next Joy machines start production mining using a low-risk place changing methodology, Metarock said.

The project will produce approximately 4 Mt of run of mine coal over four years across three production panels.

At Maxwell underground, Metarock’s PYBAR Mining Services has been named the preferred contractor for the Maxwell Underground Project Access Drifts as part of an executed letter of intent with Malabar Resources. The contract term of 12 months will commence later this year following the execution of a binding Alliance-style mining services pact.

The scope consists of twin parallel drifts around 1.3 km in length, which will provide access to the targeted coal seams. Excavation of the drifts will be carried out with metalliferous-style drill and blast equipment and methods, modified for operating within a coal mining lease.

Having only recently completed the acquisition of PYBAR and the renaming of Mastermyne to Metarock, MD Tony Caruso said: “Mastermyne’s transformation from an underground coal contractor to a diversified mining services provider is taking shape and the awarding of this project (Maxwell) is a major vote of confidence from customers in the new larger business.”

He added: “This project is quite unique in that it brings together the combination of the Mastermyne and PYBAR skill-sets, which is a real differentiator for the Metarock Group.”

3GSM tackles drill comms, pattern analysis in latest BlastMetriX UAV blasting software update

3GSM GmbH, a developer of software to optimise blasting and reduce inherent environmental issues, has announced several updates to its flagship BlastMetriX UAV software that, the company says, improves communication with smart drills, offers face profiling enhancements and delivers more sophisticated drill pattern analysis.

Robert McClure, President of Robert A McClure (RAM) Inc of Powell, Ohio, an international blast and engineering consulting firm that provides service, support and training for BlastMetriX UAV, said: “3GSM works closely with its blasting customers to adapt to new challenges faced in the field and improve blast optimisation. Customers with an active update licence automatically receive these new features inside the BlastMetriX software, or they can be ordered separately.”

The enhanced drill pattern analysis tool provides heat mapping of drilled borehole deviations for simple visualisation of differences between “as planned” and “as drilled” patterns, while semi-automatic mapping of linear rock mass features is imported into the blast plan. By providing enhanced burden and spacing information, the software allows users to adjust explosive amounts in each borehole to account for irregularities, according to the company. “This is a great tool for a company’s key performance indicator program,” McClure said. “The software captures information from each blast and allows users to go back and review historical data to correct issues in the field.”

Updates to the IREDES (International Rock Excavation Data Exchange Standard) interface improves two-way data communication between BlastMetriX UAV and smart drills. It now allows for import of measure for drilling data like drill penetration rate and air pressure to map the subsurface geology of the borehole. At a quick glance, the software shows the geology and burdens from borehole top to bottom out to the free face. The program is compatible with all major drilling equipment manufacturers, according to the company.

Incorporating the ShapeMetriX system for generating and assessing 3D images, new geological mapping integration allows users to better visualise dips, strikes, seams and voids throughout the drilling pattern. The software can characterise irregularities in the face, which are projected back through the borehole. This allows for more precise loading of the borehole and improves blast safety.

In another update, the underground volumetric measurements tool inside ShapeMetriX now provides the determination of precise volumes in a “generalised” manner, based off captured subsequent tunnel faces and perimeters.

With the aid of aerial targets or standard BlastMetriX targets as reference points, the software imports images from a calibrated DSLR camera or unmanned aerial vehicles to quickly, safely and accurately capture 3D face profiles for enhanced visualisation of the blast area. Multiple data-rich overlapping images generate hundreds of thousands of data points for accurately characterising typography of the surveyed area and creating a 3D face profile.

BlastMetriX UAV gives technicians the confidence the blast will perform as designed to mitigate fly-rock issues, high air overpressures, excessive vibration, poor fragmentation, sub-par cast, loss of grade control and wall damage, the company says.

“Through blast design optimisation using BlastMetriX UAV, operations can realise significant benefits including improved fragmentation, higher crusher throughput and lower drilling man power requirements,” 3GSM said. “The scalable BlastMetriX UAV software allows companies to integrate as much or as little technology as required.”

NRW cements Karara Mining services contract

NRW has followed up on a letter of intent with Karara Mining Limited for mining services works at the Karara Iron Ore mine in Western Australia, sealing a formal contract with the company.

PT Kaltim Prima Coal feels the effects of AECI IntelliShot electronic blasting initiation system

Having previously relied on conventional non-electric initiation systems, Indonesia-based PT Kaltim Prima Coal (KPC) has turned to AECI Mining Explosives’ IntelliShot® electronic blasting initiation system to improve the safety and efficiency of its operations.

Located close to Sangatta and Bengalon, East Kalimantan, Indonesia, KPC operates one of the largest open-pit mines in the world with coal resources of 9,275 Mt. The mine employs load and haul operations within its numerous pits, which are managed by two mining divisions: Mining Operation Division (MOD) and Contract Mining Division (CMD).

KPC commenced with coal production in 1992 and today moves approximately 500 million bank cubic metres of overburden per year, which allows the production of 60 Mt of coal. About 80% of the overburden requires drilling and blasting to enable efficient excavation, AECI says.

The mine has traditionally used conventional non-electric initiation within its CMD area, where AECI Mining Explosives Indonesia (AECI Indonesia) is contracted as the blasting services provider. This method required a lead-in-line to be run from the blast location to the firing position. In 2017, this method of initiation consumed approximately 650 m of lead-in-line per blast location, according to AECI.

High daily production targets set by KPC require multiple locations from where blasts could be initiated safely.

“Whilst this is possible within the strict safety parameters set by the mine, it sometimes requires some clever footwork, especially related to moving expensive capital equipment out of harm’s way,” AECI says. “This cumbersome method isn’t always the most efficient and often result in a loss of production time.”

AECI Indonesia, as the incumbent blasting services provider for KPC CMD since 2009, suggested IntelliShot, the company’s advanced electronic blasting initiation system.

IntelliShot has the capability to initiate one or more initiating systems wirelessly, known as remote firing. This application has the ability to generate much needed efficiencies by only using a short length of harness wire as opposed to the cost of a full lead-in-line when non-electric blast initiation is applied in the same application, the company says.

“Any new application of technology at the mine requires careful planning and demonstration of the ability to safely maintain improvement of these parameters,” it says. “The AECI Indonesia team embarked on a carefully controlled trial to test the applicability of the system and to ensure that KPC gets the full benefits.”

In addition to saving on costly lead-in lines, remote firing through the IntelliShot system offers additional safety benefits such as an advanced security system, the possibility to easily initiate the blast at larger and safer distances, allowance for the blaster to fire from locations that give greater visual security of the blast area during firing, and eliminating potential slap, snap and shoot that is possible with shock tube.

The introduction of remote firing at KPC was performed as a project and carried out in stages in the CMD area of KPC. Focused key performance indicator (KPI) targets agreed by the project team were carefully monitored on a daily basis to ensure the best possible outcome.

The project was conducted in the three CMD contractor pit areas at Sangatta and Bengalon under the management of KPC drill and blast department. AECI Indonesia successfully delivered multiple events of remote firing blasting in all areas. The team also complied with all safety and efficiency KPIs, AECI says.

The average usage of harness wire per remote firing event was around 100 m, compared with 650 m per blast of lead-in-line used in conventional blast initiation and has reduced the cost of blast initiation in KPC CMD by over 50%, AECI claims.

Yuli Prihartono, KPC Drill & Blast Manager, says: “Throughout the trial project of remote firing at CMD pits, AECI Mining Explosives has demonstrated its capability to deliver safe and efficient project to world class operations. Remote firing has successfully delivered quantifiable cost benefits for KPC. We expect AECI Mining Explosives to expand this initiative by introducing remote firing to all blast locations at CMD KPC.”
