MINE HOISTS significant saving for the mine. A further advantage of this approach to hoist technology allows for reduced technical support on site and enables ABB to support the end user with its offsite monitoring facility. SIEMAG TECBERG hoist for South Korean iron ore On March 20, 2019, the Samra Midas Group- Handuk Iron Ore Corp celebrated the official opening of its new Shaft #2 hoisting plant at Handuk Iron Ore Mine in the Gangwon-do province in South Korea. The Chairman of Samra Midas Group Woo Ohyeon, complimented the outstanding performance of everyone involved in the project including SIEMAG TECBERG. With the official commissioning of the new hoisting plant, the Handuk Iron Ore Mine is now the biggest ore- producing mine in South Korea. The new Shaft #2 is replacing the old uneconomical Shaft #1. This investment ensures the mine’s continuity for the next decades. SIEMAG TECBERG was the leading contractor for the entire shaft hoisting equipment, including the engineering, production, assembling and commissioning of two winders and braking systems, loading and unloading equipment, shaft and guide-rope installations as well as for the engineering of the headframe. This was carried out as a group-order with intercompany deliveries and performances from the SIEMAG TECBERG group locations in Germany and China. A special feature in the new Shaft #2, next to the four rope winder with an intended yearly output of up to 1.7 Mt of ore, is the arrangement of a single-rope drum winder, which will be used as a man riding winder for the underground particle physics laboratory of the Korean Institute of Basic Science. Agnico Eagle chooses ABB for Kittila As part of the development of its mining processes, Agnico Eagle’s Kittilä gold mine in the far north of Finland has invested in ABB’s production and personnel hoists. This investment will contribute to increasing the capacity of the mine and reducing the use of fossil fuels. The delivery is part of the $186 million expansion investment in the Kittilä mine by mining company Agnico Eagle Finland Oy, which started in the spring of 2018. A mine shaft over a kilometre deep will be built at the mine, from which ore will be lifted with hoisting equipment supplied by ABB. The shaft will make it possible to utilise the deeper parts of the gold deposit in an economically viable way. This will also improve the energy efficiency of the mine and reduce the use of fossil fuels, as it will replace the truck and off-road vehicle transport of ore and personnel. The processing capacity of the 14 International Mining | AUGUST 2019 mine's concentrating plant will increase from the current 1.6 Mt to 2.0 Mt per year. The ABB delivery includes one friction type production hoist with 2.5 MW of motor power as well as a 1.2 MW single drum personnel hoist. These are the first hoists in the Kittilä gold mine. ABB will also deliver online remote support services for real-time hoist condition monitoring. With ABB Ability, ABB will provide the best availability and expert support for the customer for this project. “ABB has proven to be a reliable and capable partner in mining projects. In addition, ABB has a comprehensive service network in the area, which is indispensable for ensuring production. The hoisting machine is a new critical factor in the mine production chain, where all of the above things are emphasised," said Seppo Voutilainen, Project Manager at Agnico Eagle Finland Oy. The Kittilä mine is the largest gold mine in Europe. The mine already utilises a varied range of ABB technology, including motors, an automation system, frequency converters and instruments. The current life cycle of the mine is estimated to last at least until 2035. The personnel and the production hoists will be installed and introduced at the Kittilä mine during 2020-2021. Siemens applies cloud tech for mine hoists in China To increase outputs while reducing shutdown times, YanZhou Coal Mine Co Ltd in China is for the first time establishing a cloud concept for mine hoisting, enabling it to centrally monitor production, analyse, and respond to insights from real-time data. Drawing on Siemens longstanding expertise in the mining industry and Industry 4.0, the solution will be based on the advanced architecture and performance of Siemens WinCC Open Architecture. As part of the contract, Siemens will also provide inter process communication (IPC), accessories, plus software engineering and site commissioning services. “Falling commodity prices and increasing trade tariffs, alternative energy sources, rising safety and security risks: the global coal mining industry faces major challenges while needing to meet mounting stakeholder expectations. To stay competitive, companies need to become more innovative: digitisation plays a crucial role by offering new ways to maximise productivity. For this purpose, YanZhou Coal Mine Co Ltd is establishing a cloud concept for mine hoisting.” The project is underway this year, initially drawing data from four mine hoist systems at the customer’s DongTan Coal Mine, located in the central eastern portion of YanZhou coalfield. To benefit from enterprise-wide insights, YanZhou Coal Mine Co Ltd intends later to extend the concept to cover up to 20 mine hoists located hundreds of miles apart from each other at this and its other five coal mines.” For 24/7 transparency, the cloud platform can be accessed by users on local PCs in the enterprise network, or using remote PC or smart phone/tablets via the Internet. This enables engineers and managers to monitor machine status, trace fault by historical trend, while managing service routines and the knowledge library – anytime, anywhere. YanZhou Coal Mine Co Ltd is headquartered in Zoucheng, Jining, Shandong in eastern mainland China. The company is principally engaged in underground coal mining, preparation and processing, sales, and railway transportation of coal. The most recent update to Siemens mine winder portfolio will see this infrastructure equipment benefit from not only the latest digitalisation tools, but also the highest safety standards, Roland Gebhard says. This update, on the one hand, brings its Winder Technological Controller (WTC) fully in line with the latest digitalisation standards using the Simatic S7-1500 digitalisation platform. On the other hand, it ensures the solution adheres to safety integrity level (SIL) 3, Gebhard, the company’s Product Manager for mine winders, said in the company’s Minerals Focus publication. Gebhard said Siemens is the first company worldwide to integrate this safety standard in a mine hoist. “The new controllers are compliant with most international safety standards, including the German TAS and the Chinese MA,” he said. “The safety system is used primarily for speed and position monitoring, depending on the operating mode and conveyance position in the shaft.” Additional functions of the WTC include the continuous acquisition and collection of motor, converter, brake system and mine winder data. This accumulated data is downloaded to one of the Siemens Winder Competence Centers and analysed as the basis for recommended preventive maintenance. Among the first installations to benefit from the new WTC is the already mentioned Woodsmith polyhalite mine in the UK. Hepburn Engineering acquires DavyMarkham IP Sadly the UK’s DavyMarkham, a long standing big name in hoisting and winder technology, entered administration in May 2018 but its designs live on as on February 15, 2019 Hepburn Engineering Inc (Hepburn) announced it had acquired all of the DavyMarkham’s Intellectual Property assets. The company stated: “DavyMarkham Limited was a UK-based engineering firm that designed, manufactured and serviced hoists, winches, compensating
