DMT Group has launched a new online resource to support domestic and international owners and operators of critical infrastructure, offering, it says, a full portfolio of supporting services for vital systems and assets including mining operations.

The ‘Resilience Matters’ online platform provides a broad spectrum of engineering and consultancy services designed to plan, build, support and maintain critical infrastructure across administration, energy, transport, health, and water, the company says.

This platform will act as a one-stop information touchpoint for all stakeholders and will be supported by a live-chat service with DMT’s experts, DMT said.

DMT’s offering ensures industries have access to reliable services in close digital or virtual proximity to their assets, providing remote and on-site services to enable consistent support for critical assets internationally.

“Throughout 2020, a series of travel and entry restrictions have severely reduced international mobility, and limited access for foreign nationals travelling via air, rail, water and road,” DMT said. “Many owners and people responsible for critical infrastructure rely on different subcontractors and international consultants to deliver and monitor critical services, the provision of which has been severely affected by the COVID-19 restrictions.

“As countries consider further lockdown actions into 2021, DMT’s agile ‘Resilience Matters’ approach offers comprehensive in-house support, ensuring the continuity of service regardless of current and future periods of uncertainty.”

Jens-Peter Lux, Managing Director and Critical Infrastructure Ambassador of DMT, said: “The past eight months have shown how quickly our expectations of the modern world can be upended, but critical infrastructure is too important to leave to chance. We need a rethink on how these systems and assets are protected, and there is an important role that DMT Group can play by bringing some certainty to uncertain times.

“In the months ahead, we must all work together to move past the damage and disruption of COVID-19 and our single point of information service for critical infrastructure will help to keep vital infrastructure online and in good health.”

DMT is proposing a new set of minimum mandatory criteria for engineering and consultancy around critical infrastructure to improve the resilience of assets and systems. The criteria are: proximity to assets; advanced digitisation status; redundant reserves; agility; completeness of in-house service offering; personnel contingency; and long-term relationships.

The company’s support of critical infrastructure assets includes motorways, power stations, mine shafts, healthcare facilities, waterways, bridges, structures and tunnels.

Collaboration key to unlocking digital transformation, BHP’s Bourke says

BHP has already made great strides in digitalising its processes at mine site and operations centres, but Pat Bourke, VP of Technology for Minerals Australia at BHP, says collaboration will play a critical role in helping the company leverage further operational and safety gains.

Speaking at the IMARC Online event today, he gave examples of how BHP is combining “lean concepts” with digital solutions to improve its performance through in-house collaboration.

One such example was the company’s Maintenance and Engineering Centre of Excellence, which develops advanced maintenance strategies based on data analysis to decide on what assets to maintain, when to maintain them and how to maintain them for “superior performance”.

The BHP Operating System, meanwhile, supports the company’s “front line” to improve day-to-day operations through the use of standard systems underpinned by technology, he said.

“To fully capture the next wave of productivity at speed, we need to integrate technology and our digital solutions with these initiatives,” Bourke said, explaining that this will further enhance the company’s agenda of safety and productivity.

He then moved onto the external collaboration side, saying one of the critical elements to unlocking digital transformation was the ability to collaborate within the broader ecosystem as well.

“We can do a lot as an organisation…and as an industry…in partnership with our supplier, communities and government to solve for the future,” Bourke said. “We can do even more when we effectively combine our capabilities and bring multiple partners to collaborate on shared problems.”

Thinking differently about who the company connects and creates synergies with has led BHP to find partners outside its usual circles such as the Australian Defence Force, it said. This partnership, in particular, has seen the organisations collaborate on workforce learning, culture, technology, training and shared apprenticeships.

“Through these synergies, we can stack hands together to gain further insights and understand the similarities around areas such as quantum technologies, automation and cyber defences, for example,” Bourke said.

And, even during COVID-19, the company has been collaborating to produce productivity outcomes.

This has seen it work with Microsoft to deploy augmented reality headsets that combine video with advanced 3D sensing technologies, allowing BHP engineering teams based in the Perth office, some 1,300 km away from the Pilbara operations, to oversee complex installation of mine equipment remotely.

“But it’s not just the big partners who are helping us to find a competitive edge,” Bourke said. “In today’s world we know we need to innovate and deploy new technologies even more quickly to keep up with the pace of change.”

A collaboration with start-up Plotlogic is seeing BHP pilot precision mining technology, for instance.

“This technology will map the face of a pit wall to provide a detailed view of ore versus waste,” Bourke explained. “This type of precision mining will give us the step change in productivity that we are chasing to improve the quality of the ore we extract…this will enable further efficiencies.”

Earlier this year, Plotlogic confirmed it had signed its first contract to embed OreSense, its new AI ore characterisation technology, into an iron ore mine site of BHP’s in the Pilbara of Western Australia. This technology uses hyperspectral analysis and AI to optimise ore recovery on mine sites.

Plotlogic’s vision is to enable autonomous mining operations using precise grade control with its new AI ore-characterisation technology, bringing technology that can “see and grade ore” to optimise operations and maximise yield, it says.

TOMRA’s COM XRT 2.0/1200 ore sorters have aided Lucara Diamond’s Karowe diamond operations, in Botswana, once again, recovering an unbroken 998 ct high white clivage diamond from the 100%-owned mine.

The diamond, measuring 67 x 49 x 45 mm, was recovered from direct milling of ore sourced from the EM/PK(S) unit of the South Lobe, and follows a series of significant diamond recoveries during this recent production run, including several top quality clivage and gem-quality stones of 273 ct, 105 ct, 83 ct, 73 ct, and 69 ct in weight.

“The EM/PK(S) forms an important economic driver for the proposed underground mine at Karowe and continues to produce large gem-quality diamonds in line with expectations, a further testament to the strong resource performance at Karowe,” the company said.

Last year, a feasibility study showed the company could double the mine life of Karowe by establishing an underground mine for $514 million in pre-production capital.

The 998 ct diamond (pictured) was recovered in the MDR (Mega Diamond Recovery) XRT circuit that allows for diamond recovery post primary crushing and prior to milling. The MDR circuit has, in the past, treated material in the size range between 50-120 mm. This latest recovery represents the second plus-500 ct diamond recovered from this circuit in 2020, Lucara noted.

Year to date, Karowe has produced 31 diamonds greater than 100 ct, including 10 diamonds greater than 200 ct comprising of the 549 ct Sethunya, and the 998 ct diamond.

Eira Thomas, Lucara CEO, said: “Lucara is extremely pleased with the continued recovery of large high-quality diamonds from the South Lobe of the Karowe mine. To recover two plus-500 ct diamonds in 10 months along with the many other high-quality diamonds across all the size ranges is a testament to the unique aspect of the resource at Karowe and the mine’s ability to recover these large and rare diamonds.

“Operations at Karowe have continued through 2020 and operational challenges, due to COVID-19 restrictions, have been met with professionalism by the team. We look forward to a safe finish to 2020 and continued success at Karowe as we remain focussed on strong operations to ensure maximum resource performance.”

Sandvik overcomes COVID-19 challenges to continue machine, solutions commissioning

Despite the travel restriction difficulties associated with COVID-19, Sandvik Mining and Rock Technology says it has found novel and innovative solutions to overcoming these challenges, ensuring the company maintains its leading positions in the automation and digitalisation fields.

Considering the company first introduced automation solutions into its product offering some 15 years ago and digital technologies 10 years ago, it has been leading the way in helping the mining industry adopt and embrace the modernisation revolution.

“The African mining industry has traditionally shied away from embracing new technologies, but COVID-19 has been the push factor in accelerating the necessity to adopt change, and this has happened rapidly as mines have had to learn to operate remotely and with limited resources owing to COVID-19,” Simon Andrews, Sandvik Mining and Rock Technology Vice President for Sales in Southern Africa, says.

The adoption of new technologies, however, is no longer the primary objective. Finding ways to implement them remotely has now become the focus, Andrews says.

With the philosophy of working towards finding a solution for any challenge, Sandvik Mining and Rock Technology has  introduced a headset to enable personnel to walk and talk anyone through the process of commissioning a machine and associated software without having ever seen it before.

Niel McCoy, Automation Business Development Manager for Sandvik Mining and Rock Technology, said: “This offering removes all barriers associated with the inability to connect physically on the ground and is a mechanism of training in itself.”

Coupled with this new skillset and offering is Sandvik Mining and Rock Technology’s ability to utilise its highly skilled personnel.

“Our top-level experts within the business are no longer time restricted by travel and are able to utilise their skillset across multiple mines on a more frequent basis, something we had never considered in the past but is an exercise already reaping great success,” McCoy says.

As a result of the company’s efforts in ensuring digital technologies, and the implementation thereof, remain a top agenda for clients – regardless of remote working conditions, lockdown restrictions, etc – Sandvik has established a new communication process with its clients that, it says, is paying off.

“Never before have we communicated so effectively or as frequently with our clients as we do now,” Andrews says. “We know more about our sites now than we ever did before, which naturally provides us with the ability to better assist our clients in any areas that we can contribute towards and give input on.”

DRA under budget and ahead of schedule at NST’s Jundee expansion project

DRA Global says it has completed its engineering, procurement and construction management (EPCM) contract under budget and ahead of time for Northern Star Resources at the Jundee gold mine, near Wiluna, Western Australia.

The Jundee mining operation is situated in the Northern Yandal Greenstone Belt, with the mine yielding a record 300,000 oz for Northern Star in the year ending June 30, 2020.

Jundee’s processing circuit comprises a two-stage crushing circuit, SAG and ball mill, and conventional carbon-in-leach plant. The ball mill upgrade, undertaken by DRA, increased processing plant capacity to a nominal design throughput rate of 2.7 Mt/y, from 2.2 Mt/y.

DRA delivered the EPCM project scope under budget and ahead of time, with ore commissioning achieved some six weeks ahead of schedule in a total duration of 35 weeks, it said.

“DRA’s project team achieved this outcome by working in close collaboration with the Northern Star project and operations team, the equipment vendors and construction sub-contractors,” it said.

Delivery of the project required overcoming challenges presented by the COVID-19 pandemic, including risk mitigation strategies being initiated to maintain the accelerated project schedule, according to the company.

Northern Star’s General Manager Processing, Simon Tyrrell, said DRA had consistently met and exceeded performance expectations through a collaborative approach to the Jundee ball mill project delivery.

DRA was engaged on the EPCM contract after having completed an engineering and cost study which included scope definition, design, planning, capital and operating cost estimation. The project follows several previous plant upgrades and studies successfully completed by DRA at the Jundee gold mine, which have contributed towards the continuous production growth seen at the mine over the last four-to-five years, DRA said.

The process plant shutdown and tie-in of the new ball mill was performed in conjunction with the Northern Star operations team and contractors without incident, and the process plant has since ramped up to run consistently above nameplate design capacity, the company added.

Zest WEG helps South Africa platinum miner power up

Mine operation news, Mining equipment, Mining services, Power supply for mines, Precious metals, , , , , , , ,

Zest WEG, looking to accommodate the space constraints of a South African platinum mining customer, is constructing a large diesel powered generator set to be delivered later this year.

The capacity of the 2,500 kVA genset will make it the largest unit yet to be fully load-tested at the company’s genset manufacturing facility in Cape Town, South Africa, according to Craig Bouwer, Projects and Product Manager at Zest WEG.

“In addition to functional testing, we will be equipping ourselves to conduct load testing to 11 kV on this unit,” Bouwer says. “With load-banks in-house, we will be stepping the voltage down to 400 V during the testing, and drawing on MV specialists to ensure a safe and reliable process.”

The genset is a highly technical solution to match the customer’s specific needs, he says. Based on the available space, it is housed within a 12 m ISO shipping container with the electrically-driven radiator mounted on the roof.

Prime-rated at 11 kV and powered by an MTU diesel engine, the genset has been designed in close consultation with the customer over a number of months. Having concluded the engineering design, construction is currently underway in Cape Town.

Bouwer highlighted the detailed and time consuming nature of engineering design for a project of this magnitude and complexity: “Stringent technical requirements demanded lengthy and ongoing collaboration not only with the customer, but between our engineering team and production operations,” he said. “The customer was particularly pleased with our flexibility and the extra effort we applied to ensure the optimal technical returnables for the project.”

As one of the few South Africa-based original equipment manufacturers capable of undertaking a customised genset of this capacity in-house, Zest WEG will also be supplying the control and protection panel from its range of electrical equipment and products.

“To enhance safety and ergonomics, the control panel is in its own compartment within the ISO container,” Bouwer says. “A 1,000 litre bunded day tank has also been installed inside a separate compartment within the container, including a fuel cooler and filtration system.”

The COVID-19 lockdown has had minimal impact on the work schedule, he noted, as planning and communication with the customer could continue regardless, dealing with various technical clarifications. To facilitate the transportation of this large unit to site, it will be shipped as three separate components: the genset, radiator and exhaust system. Once installation is complete – a process that Zest WEG specialists will supervise – its experts will conduct the cold and hot commissioning, and hand over to the customer.

FLSmidth’s digital R&D bearing fruit at the right time

As miners look for more digital solutions to ensure they can cope with the challenges that come with operating through exceptional circumstances like COVID-19, FLSmidth is leveraging decades of research and development to help them make this transition.

Terence Osborn, FLSmidth’s Director of Product and Account Management for sub-Saharan Africa and the Middle East, highlights that R&D is the lifeblood of the company’s new technologies. So much so, that it has some 80 projects underway to improve its mining-related offerings.

“The power of digital technology is certainly a key element of these efforts,” Osborn says. “Together with our Blue Box digital concept, based on our ECS/ControlCenter™, which is a cybersecure interface between our equipment and cloud data storage, we use our SiteConnect™ mobile app to monitor the performance of equipment and process plants in real time. The ECS/ControlCenter V8 process control platform sits at the heart of our digital vision, a key component in our growing portfolio of digital solutions and services that we call ENABLR.”

An example of this applied capability is an FLSmidth REFLUX® Classifier modular plant operating on a South Africa mine. Using SiteConnect, operations managers can have real-time access to over a hundred operational parameters on the plant. Data analytics linked to the cloud data can also generate time-based trends for instant viewing on the app.

“We have also developed SmartCyclone™ technology for our hydrocyclones,” Osborn noted. “This innovation uses sensors to detect wear and roping, a condition that reduces separation efficiency. By sending an alert when certain operating parameters are breached, the system ensures optimal efficiency is maintained, even as slurry conditions in the circuit vary.”

He highlights that the company’s machine-level solutions are offered as part of plant and process packages. At both plant and process level, there is also FLSmidth’s advanced ECS/ProcessExpert® solutions, which facilitate not just monitoring and control, but advanced optimisation enabled by state-of-the-art artificial intelligence technologies.

“It is important to remember that control systems need to be flexible, so that they adapt to customers’ needs and to their existing systems,” Osborn says. “With FLSmidth’s depth of expertise in software engineering and machine control, we can ensure that our machine-level systems connect with all market leading control systems – to seamlessly deliver the data that mines need for effective decision making.”

The company’s R&D pushes the boundaries of performance in a range of mineral processing fields. These include advancing its lamella plate technology in mineral separation applications, adapting its vertical roller mill for dry grinding in mining, and extending wear life of pumps with new polymers.

IMDEX signs agreement with Tier 1 miner to fast-track development of MAGHAMMER

IMDEX has signed a joint development agreement with a Tier One mining company to fast-track development of the IMDEX MAGHAMMER™ for commercial use, according to Chief Executive Paul House (pictured).

The MAGHAMMER uses a hybrid drilling technique combining rotary diamond drilling with fluid driven percussive drilling to achieve higher penetration rates compared with conventional coring. The technology enables an entire drill hole to be completed with a coring rig where RC and diamond drilling is required, according to the company.

IMDEX only exercised its option to acquire Flexidrill and its patent-protected drilling productivity technologies, COREVIBE and MAGHAMMER, in December, but it had carried out test work on the MAGHAMMER technology far in advance of the transaction.

Speaking at the company’s AGM this week, House reported a new rental fleet record and month-on-month increases in revenue since May as IMDEX recovered from a COVID-19-related downturn earlier in the year.

With the strength of the gold price and other key commodities, and exploration activity surging, IMDEX’s tool rental fleet is 19% up on the same time last year and exceeds the previous record set in 2012, the company said.

House told the AGM that the recommencement of activity globally since May had continued in most regions, albeit at different speeds.

“We achieved revenue of A$61.4 million ($43.5 million) in Q1 2021 (September quarter of 2020), which was up 26% on Q4 2020 (June quarter of 2020),” House said. “This result is only slightly behind the previous corresponding year at A$67.6 million, or 4.9% on a constant currency basis.”

House said the company is seeing multi-commodity demand, with clients “well-funded” and focused on resuming sustained activity as soon as possible.

The pressures of COVID-19, which forced various governments to impose border and travel restrictions, created strong demand for IMDEX technologies linked to its cloud-based IMDEX HUBIQ™, the company said.

“We have made great progress both because of and in spite of COVID-19,” House said. “The global pandemic has increased demand for our connected technologies that support remote operations. Conversely, it has hindered client trials due to limited access to site for non-essential personnel.

“On balance, the momentum for disruptive technologies such as artificial intelligence, automation, and the industrial internet of things is gaining cadence.

“The outlook for mining tech is brighter than it has ever been.”

On top of the MAGHAMMER reveal, House said client trials of the award-winning IMDEX BLAST DOG™ had resumed.

IMDEX BLAST DOG 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.

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

RPMGlobal brings Software as a Service to the haulage sector

IoT, Mining services, Mining software, , , , , , , ,

RPMGlobal has launched its first Software as a Service (SaaS) product, providing mining companies, it says, with the capability to undertake haulage calculations in a cloud environment.

With more and more operations choosing to move business-critical operations into the cloud, RPM has leveraged the growing shift from the desktop by collaborating with industry partners to launch a service-based approach to haulage calculations, known as Haulage as a Service (HaaS).

This cloud enabled, service-oriented approach to haulage analysis means users are no longer confined to one application on the desktop. Under the new SaaS model, customers are able to write their own applications to interact with HaaS. Users can then configure haul traces, haul routes, settings and trucks to run travel time calculations automatically in the cloud.

HaaS leverages the travel time calculation engine contained within RPM’s TALPAC product which has been the de-facto standard for simulation within the mining industry for more than 40 years, according to RPM. This calculation engine enables users or customer applications to undertake travel time calculations on demand.

RPMGlobal Chief Executive Officer, Richard Mathews, said: “HaaS is tailored to the current requirements of our customers to cloud-enable their operations and enable their businesses to be conducted remotely no matter where they or their people are physically located.

“Providing our customers with flexible and scalable ways to use RPM’s software is a key part of our customer service promise, and cloud-hosted options enhance our ability to support our customers through an internet-enabled cloud access to the hosted application.

“Making our innovative software available through a variety of delivery methods will remain critical moving forward and with a number of our customers undergoing the transition to cloud environments, we are proud to be at the forefront of this migration.”

The reporting and calibration benefits within the cloud HaaS offering are already resulting in miners requesting access to HaaS, RPM says. Miners are using HaaS as a way of measuring haulage performance and identifying areas of haulage improvement, including being able to automatically compare the actual values out of their fleet management systems (FMS) with calculated values, straight after the haulage route is complete on a consistent basis.

With HaaS, miners have increased operational agility to undertake haulage calculations from any location, according to the company. Because there is no desktop application, the calculations can be delivered via the web or mobile apps instantly.

Mathews said RPMGlobal’s cloud-enabled SaaS solutions help to solve several key industry challenges, including the problem of siloed data.

“With HaaS, data is no longer trapped within individual desktop applications or siloed with individual users,” he said. “This cloud-enabled approach enables operations to get the best overall haulage performance right across their operations irrespective of where the users or applications calling the cloud service are physically located.

“Mining is a dynamic and fluid environment, often making it difficult to benchmark the performance of trucks. Miners have had to use key performance indicators such as Effective Flat Haul in an attempt to normalise data. HaaS addresses this challenge by allowing miners to compare every haul against a benchmark calculated value.”

Mathews concluded: “If there can be one positive thing to come out of the global challenges of COVID-19 it is an understanding that companies need to be able to operate their businesses remotely no matter where their people are physically located, and being able to utilise SaaS applications means they can do exactly that.”
