WORLD PROSPECTS Teck’s AHS efforts speed up for RACE21 The ongoing autonomous pilot project using Caterpillar trucks at Highland Valley Copper (HVC) in British Columbia, owner Teck Resources told IM, “has progressed well in terms of safety, increased productivity and cost reductions, which is needed to enhance the feasibility of extending HVC’s mine life to 2040”. Originally, six new 793F CMD autonomous trucks were put into operation, then three more new trucks were added in 2019, bringing the total to nine, and in 2020 the fleet has again been expanded to 13, with HVC targeting a further increase before the end of 2020. By July 2020, the fleet had already safely hauled 207,000 loads, driven 920,000 km and moved 47.7 Mt. This project is notable for being the first AHS project worldwide involving a deep, steep sided pit in a cold climate. Elsewhere, there is a six-truck AHS pilot using Komatsu 930E trucks underway at Elkview for Teck to assess the use of AHS at its steelmaking coal operations. Komatsu is already well established in Canada with its AHS program through its growing fleet at Suncor’s oil sands operations. In addition, Teck plans to implement Caterpillar’s 794AC AHS kits to enable autonomous haulage at its majorityowned Quebrada Blanca Phase 2 copper mining operations currently under construction in Chile. This is all part of Teck’s RACE21™ innovationdriven transformation program with an annualised EBITDA improvement target of C$500 million ($379 million) by the end of 2020, however, Teck’s ability to achieve its targets on its planned timeline is uncertain because it will be impacted by the duration and severity of the COVID-19 pandemic. Teck says it will provide an update on timing in its September quarter reporting. There are four pillars to RACE21, which were outlined by Andrew Milner, Teck Senior Vice President, Innovation and Technology, in an interview last year. The first pillar is Renew: looking at foundational infrastructure, systems and processes, and what needs to be done to position Teck to be world class in that space, so it can support a future operating state. The second is Automate: looking at company-wide automation opportunities for robotics, processes and equipment. The third pillar is Connect: looking at how it leverages data so it can be treated like any other high-value asset to lower variability across the full value chain. And the fourth pillar is Empower: the collective impact “Renew”, “Automate” and “Connect” of looking at how Teck works, what skills it needs and how it can truly enable its people to meet these new opportunities. So, RACE21 includes a wide range of projects but core areas include unifying and modernising Teck’s core systems across its mines and establishing a technology foundation that facilitates deployment of Connect and Automate reliably, and at scale. For example: wireless site infrastructure to support automation, sensing, site communications, information access, pit-to-port integration and advanced analytics as well as accelerating and scaling up the autonomy program. Other key aims are a transformational shift in safety, reducing pertonne mining costs with smaller fleets and providing innovation platforms to enable implementation of advanced analytics to drive cycle time improvement and predictive maintenance. Part of RACE21 is also working with OEMs through the ICMM to develop zero-GHG surface mining vehicles. Another RACE21 initiative is shovelbased sensor-based ore sorting where Teck has taken a leading role by pioneering the development and implementation of MineSense for dynamic ore sorting. As of last year, this had been installed on three rope shovels using the 2nd generation ShovelSense “SX2” System. Availability increased after adopting a maintenance strategy, with early results delivering good value and full ramp-up ongoing in 2020. Teck has also been updating copper algorithms to recognise different mineral assemblages while continuing with reliability and maintenance strategy work. www.teck.com; www.cat.com/mining; www.mining.komatsu Zyfra hits drill management system milestone at Berezovskiy Zyfra has completed the 50th installation of its high-precision blasthole drill management system (Zyfra Precision Drill), which increases productivity and quality of drilling operations in openpit mines based on high-precision navigation and realtime monitoring of drilling parameters. The 50th installation happened at the Berezovskiy open-pit mine, one of the leading coal producers in the Kuznetsk Basin (Kuzbass) in southwestern Siberia, Russia. The mine is owned by the Stroyservis company. Zyfra Mining (formerly – VIST Group), a division of Zyfra, has a successful record of work in the mining industry for over 30 years with 100-plus mines using the company’s products, including mine fleet management systems and autonomous mining dump trucks. “By 2022, we plan to add our drill management solutions to 30 more locations across the globe. The next step in our continuous technology development would be the upgrade to autonomous drilling, which can include tele-operation,” Liana Meliksetyan, Chief Operating Officer at Zyfra, said. The implementation of the system allows significant improvement in the drilling process, replacing the physical control points with automated high-precision navigation on the blast hole grid. Information received from drill rigs in real time can be reported in various ways that allows quick monitoring of the drilling parameters from the machine cabin and on mobile devices, as well as to analyse rock hardness when planning the blast site. Zyfra Precision Drill can also increase the quality of blasting through automatically collected information about rock hardness. According to EuroChem, one of the world’s leading mineral fertiliser producers and an adopter of this technology, implementation of the Zyfra Precision Drill reduced idle times on average by 12 machine hours a week. GV Gold (also known as Vysochaishy), one of the fastest growing Russian gold mining companies, says the Zyfra Precision Drill implementation has significantly improved its drilling process. With the same number of drills, the blast volume has increased 20%. There was also a 15% increase of drill rig productivity and a 10% reduction of re-drilling volume among the expected results of the system implementation. Zyfra Precision Drill can run in the Cloud or on mine servers, and can provide easy data exchange between the various parties involved with the drilling, the company says. www.zyfra.com; www.suek.com 8 International Mining | SEPTEMBER 2020
