ABB and EcoHoist have executed a Memorandum of Understanding (MoU) to collaborate on the development of a vertical material transport solution for underground mines.

The solution combines EcoHoist’s technology with ABB’s technical capability and experience in vertical ore haulage in mining, they say.

The EcoHoist aims to improve on traditional vertical hoisting systems, by substantially reducing the size of the required mine shafts. This reduction in mine shaft size leads to a reduction in capital cost and construction time compared with skip hoist systems, the company says. The EcoHoist operates on electricity and provides the opportunity for mines using conventional diesel powered load and haul fleets to simultaneously cut production costs and decarbonise.

“As mines go deeper underground, and as external pressures to decarbonise mining operations increase, the EcoHoist is a compelling solution,” EcoHoist says.

The collaboration will see experts from both companies contributing to solutions for the future of underground ore haulage systems and provides opportunities for further commercial arrangements. This collaboration aims to expedite EcoHoist’s delivery of a subscale demonstration of the technology, by leveraging ABB’s expertise in engineering and hoist safety systems.

ABB has a strong reputation for delivering solutions for the mining industry, with more than 600 active production and service mine hoists within its global installed base, and EcoHoist hopes this collaboration will accelerate the adoption and deployment of the EcoHoist pilot.

Björn Jonsson – Global Business Line Manager for Hoisting at ABB, said: “The mining industry globally is poised for a sustainability step change and ABB is excited to work with EcoHoist in support of new technologies in this journey.”

Aaron Trueman – Australian Business Line Manager for Hoisting at ABB, added: “No matter the mine in Australia, the challenge is how to get ore out of the ground safely and efficiently with high availability in very remote locations. Hoists are a critical mine asset to achieve this, and novel approaches to ore haulage such as EcoHoist are what the industry needs to deliver minerals essential to modern technology.”

Matthew Forrest – Managing Director of EcoHoist, said: “I look forward to continuing to work with Björn, Aaron and other talented people at ABB. ABB’s proven track record delivering electrical drive, automation and safety systems to the resources industry provides strong synergies with EcoHoist.”

Michael Short – Business Development Engineer at EcoHoist, says the EcoHoist offers an opportunity for mining leaders interested in integrating a low-cost solution into their operation.

“We are now in early conversations with interested mining companies for collaboration projects to trial this innovative technology, aiming to increase production rates while reducing both operating costs and carbon footprint.”

ABB is launching a new digital suite of applications for hoist monitoring and optimisation, now rebranded to ABB Ability™ Smart Hoisting.

This new suite, ABB says, potentially offers further integration to other cloud solutions and extended offerings that significantly increase the operational performance and reliability of mine hoists.

The new digital suite is an important milestone in the company’s ambition to transform predictive maintenance for mine hoists. With new features such as ABB Drive System Monitoring and new key performance indicators (KPIs), ABB is opening the door to an entirely new level of mine hoist optimisation services for customers.

The traditional predictive maintenance approach relies on manual data collection and analysis over a short period of time. Intermittent issues can stay hidden or only be identified later, giving subject matter experts (SMEs) little time to program interventions exactly when needed. Additionally, manual collection and data analysis consume a significant amount of time for SMEs, preventing them from focusing on strategic performance management tasks.

ABB Ability Smart Hoisting is designed to significantly improve the uptime, availability, reliability, performance and productivity of hoists. By incorporating advanced monitoring features, the system provides actionable information on critical KPIs, ensuring better decision making and optimisation of hoisting operations. The automatic collection, monitoring and analysis of data will enable mining companies to increase production performance, identify potential functional safety hazards and optimise maintenance scheduling, ABB says.

The combination of innovative features and improved cyber security makes this solution a unique and valuable tool in the underground mining industry, the company claims.

Its predictive maintenance capabilities help increase standards and drive innovation, leading to more sustainable and profitable mining operations.

“The new and enhanced Smart Hoisting solution offers a step change in the operational performance of mine hoists,” Charles Bennett, Global Service Manager, Hoisting at ABB, said. “From improved uptime, reduced environmental footprint and increased monitoring services, this new solution brings enormous benefits to the industry at an important time.

“Through the integration of predictive maintenance and advanced monitoring, the evolved ABB Ability Smart Hoisting solution marks a pivotal milestone in redefining the performance benchmarks for mine hoists. This transformative solution addresses industry challenges comprehensively, fostering heightened uptime, sustainability and operational resilience.”

ABB says it has been a leader in developing world-class hoisting solutions for over 130 years. Powered by electricity with the possibility to run off renewable energy sources, hoists are very much a future forward solution for enabling the sustainable transformation.

To date, ABB has delivered over 1,000 hoisting solutions globally. As a supplier of complete mine hoist systems, customers can benefit from low life cycle cost, high reliability and system availability, short project execution time, and a single source of supply for complete systems, including service and spare parts.

SIEMAG TECBERG kicks off hoist construction at Benxi Longxin’s Sishanling iron ore mine

After more than five years of engagement with Benxi Longxin Mining Co in China, SIEMAG TECBERG GmbH’s Tianjin-based subsidiary has started installing the hoisting and conveying equipment at the Sishanling iron ore mine in the Province of Liaoning.

In early 2017, Tianjin SIEMAG TECBERG Machinery Co Ltd, a subsidiary of SIEMAG TECBERG GmbH, and Benxi Longxin Mining Co Ltd, which forms part of the Jianlong Group China, signed a supply agreement for three sets of hoisting and conveying systems to be divided between two shafts at Sishanling.

The Sishanling iron ore mine is one of the largest iron ore developments in China, boasting 2,500 Mt of proven iron ore reserves with an average content of about 31% Fe. It is one of the largest proven and registered iron ore deposit in China, having a long-term capacity of 30 Mt/y, with 15 Mt/y planned to be extracted in the next five years. Because of the concentrated orebody and its even distribution, these reserves are suitable for large-scale extraction, according to SIEMAG TECBERG.

The customer and the design institute initially planned a total of three production shafts to be able to extract a total of 15 Mt/y at the first stage, but after intense consultation with SIEMAG TECBERG the concept was optimised to two shafts, each yielding 7.5 Mt/y. A service shaft equipped with a total of two service winders for the transport of personnel and machinery will also be sunk.

The overall concept, thus, initially provides for a total of three hoisting systems: a double-skip production system in the production shaft in the form of a 6.75 m, six-rope machine and a cage counterweight system for personnel and machine transport in the form of a 6 m, six-rope machine and a smaller cage counterweight system for emergencies in the form of a 4 m, four-rope machine in the service shaft.

Early in 2017 orders for these systems were awarded in a public bidding procedure in which Tianjin SIEMAG TECBERG won out against international and local competitors for the supply of all three hoisting systems, not least because of the company’s capacity for system integration of very large, deep and complex shaft hoisting systems, the company said.
The current agreement requires SIEMAG TECBERG to undertake the engineering, production, delivery and supervision of the installation and initial start-up of the following equipment:

Shaft hoisting systems for raw material extraction (production shaft)

  • System 1. Double-skip hoisting system. Tower-based six-rope Koepe hoisting machine, diameter 6.75 m, for skip hoisting (55 t payload per hoisting skip) at a depth of 1,500 m with an overall drive output of 16 MW (2 x 8 MW), which is designed for a hoisting performance of 7.5 Mt/y. Split plain bearings with bearing lubrication, one set of six-rope rope sheaves for rope deflection, an ST3-F (closed loop technology) hydraulic braking system with 12 pairs of BE 250 brake elements, four sets SM150 DC indirect converters (IGCT), automation equipment including machine control system, energy distribution system and a shaft signalling and loading and unloading control system complete this hoisting system package.

Shaft hoisting systems for personnel and equipment (service shaft)

  • System 2. Large-cage hoisting system. Ground-based, six-rope Koepe hoisting machine, diameter 6 m, for large-cage hoisting with a drive output of 3 MW (2 x 8 MW). Rolling bearings, two sets of six-rope rope sheaves for rope deflection, an ST3-F (closed loop technology) hydraulic braking system with 14 pairs of BE125 brake elements, two sets of SM150 indirect converters (IGBT), automation equipment including machine control system, energy distribution system and a shaft signalling and loading and unloading control system complete this hoisting system package.
  • • System 3. Cage hoisting system. Ground-based, four-rope Koepe hoisting machine, diameter 4.5 m, for cage hoisting with a drive output of 1 MW. Two sets of four-rope rope sheaves for rope deflection, an ST3-F (closed-loop technology) hydraulic braking system with six pairs of BE125 brake elements, one set of SM150 indirect converters (IGBT) and automation equipment including machine control system complete this hoisting system package.

The special feature of the three hoisting systems is the central control system, SIEMAG Tecberg says. The control room is in the hall of the hoisting machine of the service shaft. In normal operation the hoisting systems in the production and service shaft are all in automatic lifting operation. Furthermore, the two systems in the service shaft are fitted with wireless communication devices that enable the hoisting equipment to be controlled directly from the cage. This enables personnel to reach different levels direct.

SIEMAG TECBERG started on the installation of the equipment on site in Benxi earlier this year.

Benxi Longxin has, meanwhile, begun with preparations for production shaft no. 2 to achieve the expansion level of 2 x 7.5 Mt/y in the medium term. SIEMAG TECBERG says it is supporting the customer intensively with planning and because of the initial order has a very good chance of being successful with this bid too.

ABB has signed a long-term agreement with LKAB to provide service to 12 mine hoists and, now, hoisting motors at the Kiruna iron ore mine in northern Sweden.

ABB has provided LKAB Kiruna with maintenance and hoist cycle optimisation to maximise efficiency and increase capacity at the mine since 2010. The new contract extends these services to the end of 2023, plus adds hoisting motors into the mix, with an agreement that LKAB may sign up for a further three years on a rolling basis, ABB says.

Most of the ore mined at Kiruna is at depths of more than 1 km, with large solid slabs of iron ore extending several hundreds of meters down into the ground. Local ABB engineers, supported by ABB globally, have worked on site at Kiruna to increase hoist capacity through a reduced hoist cycle time to optimise production. They have improved equipment use, balancing capacity and wear and tear of the hoist equipment, the company said.

Peter Ylivainio, Senior Maintenance Engineer at LKAB, said: “LKAB places great emphasis on refining every element of the underground mining process, in order to make it as efficient as possible. Mining ore at great depths is a logistical challenge that places demands for a well-functioning infrastructure and safe and resource-efficient production, with well-developed production methods and processes vital. We have a long successful relationship with ABB and their local presence, global expertise and remote operations technology support our goals.”

Erik Kjellgren, Strategic Account Manager, ABB, said: “This new agreement means ABB will ensure optimal capacity, greater efficiency, lower energy consumption and extended equipment lifecycles across control systems, motors, drives as well as the hoists up to 2023 and beyond. Our experienced team of engineers provides regular support to LKAB and we look forward to seeing increased benefits for our customer in terms of insights and actions to optimize equipment performance.”

The hoists are the main artery of the production flow at the Kiruna mine as they raise the ore hundreds of meters from the sublevel to ground level. Their continuous operation is critical for safety and to prevent costly interruptions to production, according to ABB. LKAB’s extended service agreement with ABB is designed to ensure the maximum reliability and availability for the hoist control system, motors and drives located both above and below ground.
