ContiTech is taking an unusual service approach in the world’s largest underground iron ore mine in Kiruna, Sweden.
Hannover, Germany, October 2017 – Kiruna is situated north of the Arctic Circle and is roughly a 15-hour train ride away from Stockholm. It is Sweden’s northernmost town and arose as a settlement for the mine of the same name. Here, in the world’s largest underground iron ore mine, for around 120 years government-owned mining company LKAB (Luossavaara-Kiirunavaara Aktiebolag) has been extracting some 27 million metric tons a year of the sought-after raw material. The Guardian once reported that this amount could be used to build six Eiffel Towers a day. And most constructors in Europe using iron ore opt for the superior-quality Kiruna magnetite, which has an iron content of 60 to 70 percent. But LKAB also exports the material to markets all over the world. The crude ore in Kiruna is used to manufacture 15 million metric tons of finished products, and the material is mostly shipped in the form of pellets. The Swedish Ore Railway is used to transport it to the ports of Luleå and Narvik in Norway. At the loading station the trains tip out their freight, where conveyor belts either transport it to stockpiles or directly to the ships.
Since the year 2005, a RopeCon® system by Doppelmayr Transport Technology GmbH, Austria, has been transporting inert material along a long-stretched valley at the Tüfentobel landfill site, which will eventually be backfilled. The belt is being extended in several stages. It discharges the material onto a debris cone directly where it is to be used. Finally in March 2016, a novel concept was implemented which has further increased the flexibility of RopeCon®.
Conditions in underground mining range from arctic cold to extreme heat and are especially hard on man and machine. At the Ugol Rossii & Mining Trade Fair, (6-9 June, Novokuznetsk), Flexco GmbH will be showcasing solutions that not only allow conveyor system operators to improve their processes, but also greatly simplify maintenance and repair work. The solutions on show will include the new belt centring station PT Pro EZ, which detects a skew and realigns the belt correctly – an important step in preventing material losses.

Neponset, IL, USA, March 2017 – In another move toward “smarter” material handling, a global conveyor technology innovator has introduced an automated pneumatic tensioning system for belt cleaners. The new offering from Martin Engineering delivers precise monitoring and tensioning throughout all stages of blade life, reducing the labor typically required to maintain optimum blade pressure and extending the service life of both the belt and the cleaner. Equipped with sensors to confirm that the belt is loaded and running, the system automatically backs the blade away during stoppages or when the conveyor is running empty, minimizing unnecessary wear to both the belt and cleaner. The result is consistently correct blade tension, with reduced power demand on start-up, all managed without operator intervention.

To connect the El Limón gold ore pit with the processing plant it was necessary to overcome an altitude difference of approx. 400m in steep terrain. Minera Media Luna, S.A. de C.V. (MML), 100% owned subsidiary of Torex Gold Resources Inc., opted for the RopeCon® by Doppelmayr Transport Technology as a means of transport. Along with other aspects, safety and environment were key considerations in prompting the decision. The system transports 1,000 metric tons of gold ore per hour into the valley over a distance of 1.3km. (Published on YouTube on May 9, 2016)
