Brokk, a leading manufacturer of remote-controlled demolition robots, has introduced the Brokk Pedestal Boom, a compact, stationary breaker boom system for the mining and aggregates industry.

The new machine range allows producers to apply the power and precision of Brokk’s demolition robots to primary breaking tasks that feed mobile crushers, jaw crushers, gyratory crushers and grizzlies.

The Brokk Pedestal Boom, Brokk says, offers an unrivalled range of motion, pairing Brokk’s three-part arm system with 360° slewing for maximum versatility in underground applications. The unit can be operated with either the tethered remote or from a control room.

Depending on network configuration, the machine can be manoeuvred from 2,000 m away or longer, using Brokk’s SmartRemote™ technology to increase safety and efficiency.

The standard remote operation solution features remote-control, intuitive controls and professional-grade radio technology with a 300 m working range, allowing operators to maintain the best view possible while staying safely out of harm’s way.

The networked remote operation solution allows operators to control the robot while sitting in an office, which, depending on network configuration, can be located 2,000 m away or longer. The machine is connected and operated over Ethernet or Wi-Fi.

The standard video option includes two cameras on the machine and an operator’s desk with integrated controls and video screen. Upgrades are available, including additional cameras for better visuals and optical zoom cameras. One control system can be paired with up to six Brokk Pedestal Boom systems.

Brokk will showcase the Brokk Pedestal Boom (the Brokk 300) and highlight other robotic mining solutions at MINExpo 2021, September 13-15, in Las Vegas.

Martin Krupicka, President and CEO of Brokk Group, said: “Brokk saw an opportunity to give our customers a better solution for breaking oversize rock in crushing and grizzly applications. We’ve developed technology that is powerful, compact, flexible and easy to install. The new Brokk Pedestal Boom provides a plug-and-play solution that is perfect for underground spaces with low headroom or other space constraints. We are leveraging our 45 years of experience and proven technology platforms to create a smart, safe and user-friendly solution.”

The Brokk Pedestal Boom is based on the proven arm system and power pack of Brokk’s demolition robots. The machine body is then mounted on a pedestal, rather than tracks. This allows the machine to be installed in a stationary position next to a crusher or any area where primary breaking is needed, the company says.

Unlike existing breaker boom options in the market, the Brokk Pedestal Boom system integrates the power source and arm for a compact breaking solution with just a single power cable. No external power pack or hydraulic hose connection is needed.

Model sizes for the range include the Brokk 200, Brokk 300, Brokk 500 and the Brokk 900 Pedestal Boom, which is capable of producing 3,050 J/Nm at a rate of 330-680 blows per minute with the BHB 1500 hydraulic breaker to power through even the toughest rock formations.

The Brokk Pedestal Boom offers more flexibility in underground and confined space applications, Brokk says. The three-part arm design allows producers to reach closer to the crushers and manoeuvre in as little as 1,800 mm of height clearance. This, paired with the unit’s 360° slewing capabilities, means operators can maintain the best angle against the material for efficient breaking.

Brokk’s compact and more flexible three-arm system also makes maintenance and switching attachments easier, especially in areas with space constraints.

The Pedestal Boom comes standard with a corresponding BHB hydraulic breaker for optimal efficiency and breaking capacity.

“Worker safety is a major focus for many companies and Brokk actively searches for ways to make every aspect of our customers’ processes safer,” Krupicka said. “Over the years, our demolition robots have helped mechanise a number of high-risk, heavy labour tasks such as scaling, drilling and secondary breaking. The new Brokk Pedestal Boom range addresses one more challenge, enabling customers to efficiently complete work without any health and safety risks.”

Komatsu and Vale are set to reveal more about their underground hard-rock mechanised cutting technology collaboration at the upcoming MINExpo 2021 event next month.

The companies, through the Canada Mining Innovation Council, have been engaged on a project to advance the future of underground hard rock excavation through optimising use of Komatsu’s DynaCut mechanical cutting technology.

The technology was previously tested at the Cadia underground mine in New South Wales, Australia, operated by Newcrest Mining, which IM revealed last year as part of an exclusive interview with Vale’s Luke Mahony, Head of Geology, Mine Engineering, Geotechnical and Technology & Innovation for the Global Base Metals Business; and Andy Charsley, Project Lead and Principal Mining Engineer, Technology & Innovation.

Vale and Komatsu will start trialling DynaCut’s capabilities on Komatsu’s new MC51 machine at Vale’s Garson Mine in Sudbury, Ontario, Canada, shortly, working together to increase the pace at which the innovative technology will be available to the larger market.

The machine is set up at Garson and expected to start cutting in the next month, IM understands.

“True innovation requires effective collaboration between the end user and suppliers to ensure the technology meets the needs of the industry,” Dino Otranto, Chief Operating Officer of North Atlantic Operations and Asian Refineries for Vale, said. “This partnership is that first step to really prove and understand the technology, while meeting our high standards for safety.”

Through more than 10 years of research and development, Komatsu says it has determined how to break rock continuously and precisely through a fully-electric system that outputs zero emissions. By automating and controlling processes so the machine can be operated remotely via line of site, Komatsu customers can move their operators further from the cutting face and from harm’s way leveraging DynaCut technology and the MC51 machine, it said.

Rudie Boshoff, Director of Hard Rock Cutting Systems at Komatsu, said: “We’re excited to be trialling this new machine and technology because it offers the potential to really change the way our customers mine. Not only does the DynaCut technology provide a very controllable way of cutting rock – within 50 mm accuracy to plan – the machine itself, the MC51, is designed to advance more sustainable mining methods by reducing the amount of equipment required to get to the orebody.”

Komatsu and Vale will be co-presenting about their partnership to drive innovation on September 13, 2021, on stage at the Komatsu booth in Las Vegas.

Just this week, Hillgrove Resources said it was set to trial the DynaCut technology on an MC51 machine to develop a portal and underground decline at the Kanmantoo mine in South Australia following a A$2 million grant from the South Australia Government.

The Wirtgen Group is planning to present its field-tested 220 SM(i) 60 ton (54 t) class surface miner for the first time on the North American continent at next month’s MINExpo 2021 event in Las Vegas.

With a cutting width of 2.2 m and a cutting depth of up to 300 mm, the new 220 SM(i) surface miner (pictured) is an ideal choice for the selective extraction of minerals, routing operations and infrastructure projects, according to Wirtgen. A particular highlight of the 220 SM(i), which offloads extracted minerals in windrows, is its spacious ROPS/FOPS operator’s cabin. It can be heated or air-conditioned and is soundproofed and isolated from vibrations, the company says. An operator-friendly multifunctional joystick controls all key functions of the machine.

In addition to the 220 SM(i), Wirtgen plans to preview the successor to its 2500 SM at the show, which runs from September 13-15.

Sales of the 280 SM(i) surface miner are scheduled to begin at the turn of the year. The highlight features of the new 280 SM(i) include a slewable operator’s cabin, with the machine’s technological innovations working together to ensure high overall productivity and cost-efficiency, Wirtgen says.

Wirtgen will be adding more new models to its range of surface miners. The first of these will be the 260 SX(i), which is not designed primarily for traditional mining applications, but for use in large-scale infrastructure projects such as the construction of railroads, drainage canals, freeways and highways and the enlargement of tunnels.

HARD-LINE plans to unveil a diverse line-up of new mining products geared towards automation and safety at MINExpo 2021 next month.

The company’s Auto RockBreaker, TeleOp Assist and Brow Alert will be just some of the company’s booth highlights from September 13-15, in Las Vegas.

HARD-LINE’s Auto Rockbreaker is going to “disrupt” the mining industry, according to the company.

“For the first time ever, operators will have the ability to automate many rockbreaking tasks” HARD-LINE said. “With Auto Rockbreaker, mining companies will be able to reduce maintenance and operator training costs, decrease wear and tear while extending the life of all rockbreakers.”

The system has many functions, including auto deploy and auto park, as well as other features making the operator experience that much more intuitive with its 3D User Interface, it said.

TeleOp Assist is the latest addition to the company’s TeleOp suite, which equips the base TeleOp system with intelligent steering assistance and collision detection to keep machines off walls while driving.

Using real-time 3D LiDAR scans, Assist will automatically steer to handle the articulation adjustments required to keep the machine as centred as possible within the drift, the company said.

“With Assist’s adaptive technology, a pre-scan of the drift is not required – providing significant cost savings,” HARD-LINE said. “The system does not require any training when moving from one level to another.”

Brow Alert, meanwhile, is an added level of protection for underground mining operations.

It serves as an add-on system designed to deter an operator from manually driving a vehicle past the brow line of a stope by using sensors and modules.

The system is easy to install, reduces risk of workplace injuries and fatalities, encourages accountability and keeps operators a safe distance from the brow, the company says.

Auto RockBreaker, TeleOp Assist and Brow Alert will be joined by the likes of RRC (Radio Remote Control), TeleOp system, vehicle conversion kits (drive-by-wire), and HARD-LINE’s low-profile loader series (LP401 and LP301) on the company’s MINExpo booth.

Robit’s ‘built to last’ philosophy on show with newest products

Environmental, Explosives and blasting, Mining consumables, Mining equipment, Mining services, Steel and iron ore, Sustainable mining, , , , , , , , ,

Robit has launched two new products that, it says, have been designed to deal with the harshest mining conditions.

Its tubeless range of high-performance down-the-hole (DTH) hammers and the Robit Extreme Carbide are made for environments where wear and tear are a constant factor, the company says.

The new range of tubeless DTH WH TL hammers has been designed to eliminate the risk of foot valve breakages and the resulting operational downtime, according to Robit. Not only has the foot valve been removed to enhance reliability, but the design of the hammers has been further revamped to bring maximal usability in a minimal footprint, making them ideal for both blasthole and energy well drilling applications, Robit said.

The integrated choke system allows for airflow adjustments to suit the compressor and improve flushing, Robit says. The hammers’ inner liner allows optimal airflow and provides improved performance in wet conditions. The piston, itself, has been redesigned for improved strength and optimal performance. The hammers are suitable for ground conditions with high volumes of water or in soft unconsolidated ground, according to the company.

The Dual Property Extreme Carbide, meanwhile, is built to last.

Customer trials conducted in North America showed bit life improvements of over 50% when drilling in highly abrasive ground conditions, making it the ideal choice for blasthole and well drilling applications, Robit claims.

The Dual Property Extreme Carbide has a wear-resistant outer layer that uses the Robit Extreme grade #4 carbide. This is specifically formulated for highly abrasive ground conditions, staying sharper for longer while increasing productivity and reducing the number of necessary regrind processes. Furthermore, the Robit Extreme Carbide has been developed to reduce the overall CO2 impact of drilling and to improve the sustainability of Robit products, the company says.

Under the outer layer of wear-resistant Robit Extreme Carbide, the inner core is made of standard grade #1 carbide. This makes it strong and durable against fracturing, all the while guaranteeing the DTH bit performs at the same high level as Robit standard quality carbides are renowned for once the outer layer has eventually worn away. And for customers that do not re-grind drill bits, preferring to “drill-to-destruction” or “run-to-life”, the Robit Extreme carbide has shown to be even more advantageous, Robit says.

The recently-released Robit Rbit button bit series is also showcasing the company’s sustainability credentials. Made of 100% recyclable steel and finalised with eco-friendly water-based paint, the Rbit is designed to achieve the fastest rates of penetration and lowest cost-per-metre drilling in the company’s range.

All these products will be presented at the company’s MINExpo 2021 booth in Las Vegas, September 13-15.

The founding members of the alliance are Rio Tinto, BHP, Codelco and Boliden.

Through the alliance framework, Komatsu’s GHG partners will work directly with Komatsu to actively collaborate on product planning, development, testing and deployment of the next generation of zero-emission mining equipment and infrastructure, the OEM said. The alliance’s initial target is advancing Komatsu’s power-agnostic truck concept for a haulage vehicle that can run on a variety of power sources including diesel-electric, electric, trolley (wired), battery power and even hydrogen fuel cells.

“We are honoured that our customers, several of the largest mining companies in the world, have agreed to participate in the Komatsu GHG Alliance and work in partnership with us to develop sustainable solutions for mining,” Masayuki Moriyama, President of Komatsu’s Mining Business Division, said. “We look forward to close collaboration with these industry leaders to accelerate development and deployment of the next level of equipment designed to reduce greenhouse gases from mining operations and ultimately achieve the goal of zero-emission mining.”

The formation of the alliance brings together mining leaders willing to share time, resources and information to deliver zero-emissions equipment solutions, Komatsu said. The company intends to expand the alliance to additional mining companies to enhance industry-wide collaboration on solutions to decarbonisation.

In a separate release, Rio Tinto said it will conduct a pre-production trial of the new equipment at a site and has the option to purchase some of the first trucks from Komatsu once they are commercially viable.

Alf Barrios, Rio Tinto’s Chief Commercial Officer, said: “Rio Tinto and Komatsu have a shared history of partnership on innovation going back to when we built the world’s largest Komatsu autonomous haulage fleet in 2008.

“Our support of a trial, and the option to buy some of the first trucks from Komatsu, underscores our shared commitment to actively collaborate on product planning, development, testing and deployment of the next generation of zero-emission mining equipment and infrastructure as we look to decarbonise our business.”

As a company, Komatsu, meanwhile, says it is committed to minimising environmental impact through its business, targeting a 50% reduction in CO2 emissions from use of its products and production of its equipment by 2030 (compared with 2010 levels) and a challenge target of achieving carbon neutrality by 2050.

Komatsu has worked to reduce greenhouse gas emissions for customers through product development for decades in many areas including electric diesel dump trucks, electric power shovels, regenerative energy storage capabilities and fuel saver programs, it said.

The company’s initial concept for a haulage vehicle that can run on a variety of power sources, part of the power-agnostic development, is set to make its official debut at MINExpo 2021 on September 13-15 in Las Vegas, USA.

As the world’s largest mining event, MINExpo INTERNATIONAL is used as an industry barometer for the health of the sector. While this year’s event will be a little different given the impacts of COVID-19, the anticipation continues to build for an in-person gathering that will highlight the biggest and best mining has to offer.

Ahead of this year’s event, sponsored by the National Mining Association (NMA) and due to take place on September 13-15, in Las Vegas, IM put some questions to Jeffrey Dawes, MINExpo INTERNATIONAL 2021 Chair. Dawes is also VP of Komatsu’s Global Mining Business Division and President and CEO of Milwaukee-based Komatsu Mining Corp.

IM: How will this MINExpo be different to previous editions? How are companies planning to ‘open up’ their exhibits and presentations to the widest audience possible considering COVID may restrict some of the in-person international attendance seen in previous years?

JD: MINExpo offers the mining industry the unique opportunity to experience, in person, the newest mining equipment and talk directly with the technical experts behind the most innovative technology and solutions. NMA has done a great job adapting plans this year as COVID restrictions have evolved, so they were prepared for a very different experience if need be, but fortunately it looks like we will be able to have a fairly normal show experience, albeit from a North American perspective – we will be missing some of our international friends who cannot join this year’s event. Part of what has always made our industry great is a strong sense of community, so it will be great to be able to get together in person after such a long time.

To accommodate our friends and colleagues who won’t be able to make the show in person, exhibitors this year have plans to utilise the latest in virtual technology to showcase what will be at the show. Exhibitors will also be able to upload product information, videos and other materials to the online directory, which will be available and open to anyone for a year after the show. Finally, the Opening Session will be live streamed.

Jeffrey Dawes, MINExpo International 2021 Chair

IM: What will be the big innovation themes at the event and what do these themes say about the future direction of the mining industry? 

JD: Digitalisation, electrification and automation will be the big innovation themes this year. Full enterprise optimisation can only be achieved by connecting tasks, processes, systems and people across the value chain. Solutions that leverage digitalisation, electrification and automation are the key to that full enterprise optimisation. They also play a crucial role in creating sustainable systems that support society’s growing needs in the most environmentally responsible ways.

IM: In a general sense, what positive impacts do you think COVID has had on the mining sector’s innovation/technology uptake? Has it accelerated the rate of innovation through necessity (remote working, increased HS&E considerations, shift to cloud-based network infrastructure, etc)? Is this likely to shine through at MINExpo in terms of what companies are showcasing and talking about?

JD: COVID really gave the mining industry a chance to reflect on its goals and take a deeper look at the tools now available to help it reach those goals. I think it also helped us gain a better understanding of the importance of aligning our business objectives – to extract the minerals needed by society – with society’s need for us to do that in the most sustainable, efficient and least intrusive ways possible. I’m certain that the products and solutions presented by the exhibitors at MINExpo this year will centre on the innovations and technology available now and in the near-term future that will help mines meet both their own and society’s needs.

IM: How do you see Komatsu’s contribution shaping/influencing the event? Are your solutions likely to be the ‘talk of the show’?

JD: We think so, yes. This year at MINExpo, Komatsu will focus on the power of smart technology and connected systems, the freedom of interoperability on an open platform, and the equipment and solutions that will help our industry move forward toward a more sustainable future. I’m particularly looking forward to sharing our newest haulage concepts, which are designed to help meet our customers’ needs for autonomy and the drive toward zero emissions. We’re also excited to give attendees their first in-person look at our newest surface blasthole drill, with 122,000 lb (55,338 kg) of pull-down force, the ZR122. Also, our newly branded WE1850 Gen3 wheel loader with switched-reluctance hybrid drive technology, with a bucket capacity of 60 tons (54 t), and our latest offerings for underground hard-rock and soft-rock operations.

Ultimately, at Komatsu we believe in providing our customers with the technology, solutions and flexible support they need for the lifecycle of their equipment and mining operations. Our customers need a reliable partner they can trust with whom to invest for the future of mining. We aim to be that partner.

IM: Aside from being a topic of discussion on the stands and in the conference rooms, how will sustainability be on show at MINExpo? Will this be the most ‘sustainable’ MINExpo yet in terms of organisation, emissions, etc?

JD: Mining has always been an essential part of keeping modern society moving forward. As we say, if it’s not grown, it’s mined. As an industry we have to focus on how to evolve to continue to meet those needs sustainably. The mining industry is already finding new ways to extract the minerals needed to meet the requirements of the world’s more energy conscious and environmentally friendly future. I am sure that many of the exhibits at this year’s show will showcase those new sustainability-focused solutions.

IM: Are you able to provide any preliminary expectations of attendee numbers?

JD: Varying country restrictions – and the US’ own restrictions – are obviously making this a year unlike any other, placing unusual limitations on attendance. However, we were pleased to have nearly 90% of our 2020 planned exhibitors re-book for this year and new exhibitors are booking space every day. We’re looking forward to welcoming representatives from 32 countries as both exhibitors and attendees. We hope to see even more attendees register as vaccination rates continue to rise, case numbers fall and an increasing number of countries lift travel restrictions as evidenced by recent changes in Canada.
