Caterpillar lowers UG mining costs, downtime with release of bolt-together LHD buckets

Caterpillar has launched “bolt-together” buckets for underground loaders that, it says, offer the same strength and durability as standard buckets, but reduce time and costs associated with transportation, assembly and rework procedures for underground mining.

The new bolt-together bucket does not require skilled maintenance operators for underground welding, resulting in a reduced safety risk, according to the company. On top of that, the design allows for efficient underground assembly, where the loader is working, to cut replacement time and lead to lower machine downtime and higher productivity.

“Optimised for moving abrasive underground materials, the new bucket design includes improved material thickness for increased strength and a rigid bucket assembly to aid in easier edge installation and removal,” Caterpillar says. “High-grade, 400 BHN materials used for bucket assembly components and high-grade wear protection ground engagement tools (GET) on the removeable shroud assembly deliver a long bucket service life for better cost saving and productivity. With proper GET selection and management, the Cat bolt-together bucket is designed to last through the first machine overhaul period to reduce replacement downtime.”

The buckets are modular in design for quick installation and removal, with the Cat GET available for the new bolt-together buckets including three edge options – bolt-on half arrow, modular weld-on and Durilock – shroud segments, and rock guard to deliver reduced downtime and accelerated repair.

The new bolt-together bucket is available in a range of capacities from 5.3-7.5 cu.m, specially designed for the Cat R1600H, R1700G, R1700 and R1700 XE LHD models. They are built in the same factory and go through the same stringent quality control process as Cat equipment and are supported by the global Cat dealer network, the company says.

Cat to use NMG’s Matawinie graphite mine as ‘zero-emission machine’ testbed

Nouveau Monde Graphite and Caterpillar have signed an agreement pursuant to which Caterpillar will develop, test and produce Cat® “zero-emission machines” for the Matawinie graphite mine, in Quebec, Canada, with a view to becoming the exclusive supplier of an all-electric mining fleet for deployment at the mine by 2028.

Looking to accelerate and tailor the equipment development, Caterpillar will engage with Nouveau Monde’s team to incorporate “voice of customer” throughout the development, and for testing of the zero-emission fleet and infrastructure prior to commercial production, the companies said.

To this point, Caterpillar has only disclosed the development of a battery-electric 15 t LHD, the R1700 XE, however it came to light just over a year ago that the OEM was working on a separate project called ‘Project Verde’.

Brian Weller, Chief Engineer, Surface Mining & Technology, Caterpillar Inc, previously stated on Project Verde: “Caterpillar has responded to customers by launching a project that is focused on energy and emissions reduction, and helping customers decrease their carbon footprints through machinery and power solutions that contribute to lower greenhouse gas.”

Speaking about the latest agreement between NMG and Cat, Arne H Frandsen, Chairman of Nouveau Monde, commented: “I recall our first meeting with Caterpillar some two years ago, outlining our vision of a zero-emission mine in Québec. Our commitment to this vision has taken us to this very important moment, not only for Nouveau Monde, but for the global mining industry as a whole. Today, alongside Caterpillar, which in my opinion is the most trusted and reputable supplier of heavy-mining equipment worldwide, we can bring the zero-emission machines vision into reality.

“I think it is remarkable that Nouveau Monde, as a representative for the new style green resources industry, is part of spearheading the electrification of the industry, by collaborating with Caterpillar.”

Eric Desaulniers, Founder, President and CEO of Nouveau Monde, added: “We are proud to be a driving force for our peers as we strive to electrify our operations to meet our carbon neutrality commitments while maintaining the productivity and efficiency standards of our mining operations. Even more gratifying and important to our corporate mission is that our project can serve as a springboard for the future of the mining industry by collaborating with Caterpillar on these cutting-edge technologies.”

Denise Johnson, Caterpillar Group President, said: “The collaboration between Caterpillar and Nouveau Monde marks an important milestone in the mining industry. Through integrated technology, machines and services, the entire Caterpillar team is proud to support Nouveau Monde as they work towards constructing and establishing their first zero-emission mine.”

In November last year, NMG issued an “international call for pre-qualification” related to the fleet and charging infrastructure at Matawinie following work by the company’s International Task Force Committee. This work had allowed Nouveau Monde to explore “technologies, best practices and operational parameters to bring its vision to life in a cost-effective and technologically advanced way”.

As part of this pre-qualification program, companies were able to submit detailed proposals and performance specifications from their production equipment solutions between November 30 and January 30, 2021.

In the 2018 definitive feasibility study on Matawinie, Medatech Engineering Services Ltd and ABB Inc – both companies in Nouveau Monde’s taskforce committee – came up with the fleet outline at Matawinie.

“The mine will be using an all-electric, zero-emission mine fleet, consisting of electric battery-driven 36.3-t mining trucks, battery-driven front-end loaders, cable reel excavators and bulldozers, and battery-driven service vehicles,” the report read.

The mine, scheduled to produce 100,000 t/y of graphite concentrate, was also expected to use an electric in-pit mobile crusher and overland conveyor system to feed crushed material to the plant.

Caterpillar, Barloworld to talk up mining equipment and power solutions at Indaba

Caterpillar and its southern Africa dealer, Barloworld Equipment, are set to present a broad range of machines, technology and support services at next week’s Mining Indaba, in Cape Town, South Africa.

The Caterpillar exhibit at Indaba, running from February 3-6, will feature digital displays of electric power generation systems, surface and underground mining equipment, and Cat MineStar™ technology capabilities – ranging from vehicle safety systems, such as operator fatigue monitoring, to production systems using teleremote, semi-autonomous and autonomous machine operation.

Caterpillar has recently introduced several new underground hard-rock mining vehicles in Africa. The new R1700 underground LHD brings the latest technology for semi-autonomous and fully autonomous operation to the region. The loader also delivers more than 30% greater fuel efficiency, 65% more lift and tilt force, and 15 t capacity – 20% more than its predecessor, yet in the same dimensional envelope, according to Cat.

Using MineStar Command for underground, the new R1700 (pictured) can be operated from a remote location to keep miners away from potential hazards, Cat says. “The system also boosts utilisation by allowing immediate entry after blasting and by reducing shift change time to nearly zero.”

In addition to the R1700, Caterpillar has introduced several LHDs and underground trucks equipped with EU Stage V engines and emission controls. “Reducing emissions helps miners improve the underground working environment,” it said. On top of this, and with the goal of zero underground emissions in mind, Caterpillar is continuing to develop the battery-powered R1700 XE.

Erik Elsmark, Region Manager for the Caterpillar Underground Mining Division, said: “Caterpillar and Cat dealers are supporting the whole African continent and all types of underground mining applications – big and small mines and all minerals.

“In the past several months we have delivered machines covering our full product range, demonstrating that we are well positioned to meet our customers’ needs.

“Starting with our AD22 underground articulated truck to our R2900 LHD, our equipment delivers exactly the size class and power needed for the application. With distribution centres in Southern Africa and Middle East and our dealer network in all countries of the African continent, we are able to achieve world-class service.”

The extensive line of Cat surface mining machines and technologies will also be a talking point at the event.

Caterpillar has recently expanded its line of electric drive mining trucks in the past year to include the 794 AC, 796 AC and 798 AC. Recently, a South Africa mining operation took delivery of several 794 AC trucks (pictured above), which have 291 t capacity, the company said. “This model has already proven its high productivity and superior speed on grade in a wide variety of applications,” Cat remarked.

In the Cat drill line, the latest model is the MD6200 rotary blasthole drill, designed as a production drill with the flexibility to do pre-split drilling – all in a package that Caterpillar says is its most transportable rotary drill yet. The MD6200 is designed to perform rotary or DTH drilling in single-pass or multi-pass modes and can drill holes of 127 to 200 mm in diameter, according to Cat.

Cat MineStar Command now includes systems for autonomous operation of mining trucks, semi-autonomous operation of dozers, and semi-autonomous as well as autonomous rotary drills. These systems enhance safety, boost production and lower cost per tonne, Cat says.

Mine power experts will also be on call at the show, with the representatives keen to talk about the ability for Cat generators to deliver reliable, continuous power, temporary power, or a combined heat and power solution. “The Cat team customises and installs systems for every phase of mining,” it said.

Caterpillar says it offers the industry’s widest range of diesel, gas and dual fuel generator sets; automatic transfer switches, and switchgear for seamless integration. Additionally, it offers microgrids, fully-integrated power systems that utilise solar panels, energy storage and monitoring and control systems in conjunction with any configuration of Cat gen sets.
