ALROSA Udachny mine commissioned with capacity to be reached by 2019ALROSA Udachny mine commissioned with capacity to be reached by 2019

first_imgALROSA Group has now commissioned its Udachny underground mine which is now on the way to reaching its design capacity of 4 Mt/y of ore. This rate of mining will make Udachny the largest underground diamond mine in Russia and one of the largest worldwide. The underground mine is expected to reach its design capacity in 2019.In the second half of 2014 diamond mining at Udachny will be ancillary to the orebody development. Commercial production is to start in 2015 to reach 2.4-3.0 Mt/y of ore by 2016 and 4 Mt/y by 2019. The underground project is to mine about 72.3 Mt of ore by 2034. The additional prospective resources are estimated at 72.8 Mt of ore. Once the design capacity is reached, Udachny underground mine will be able to provide over 5 Mct of diamonds per year.Open-pit mining at the Udachnaya kimberlite pipe, one of ALROSA’s largest deposits discovered in 1955, started in 1971. Rough diamonds mined at Udachnaya throughout its operation totaled some $80 billion. Open-pit mining at Udachnaya pipe is expected to be fully completed in 2015, and until then underground mining and operations in the open-pit mine will be parallel.Udachny is the forth in succession and the largest underground mine operated by ALROSA. Today ALROSA operates the International and Aikhal underground mines with the design capacity of 500,000 t/y and the Mir underground mine with the design capacity to reach 1 Mt/y of ore. “An ambitious program for the construction of underground mines is an integral part of ALROSA’s development strategy aiming to keep its world’s leading position in terms of rough diamond mining and ensure the diamond mining growth up to over 40 Mct. The launch of the Udachny underground mine will allow the company to maintain stable volumes of diamond production in Western Yakutia for many years,’ Fedor Andreev, ALROSA’s CEO, said at the official start-up ceremony.last_img read more

ABB Dodge CST drive systems at Titania mineABB Dodge CST drive systems at Titania mine

first_imgEurope’s first Dodge® controlled start transmission (CST) drive system is installed on a 700 m conveyor at a mine in Norway, providing the reliability required to overcome lost production from breakdowns. The Titania A/S mine located in Sokndal, Norway is the world’s largest open cast ilmenite mine, producing nearly 850,000 t/y per year of TiO2, the widely traded powder used in the whitening of products from paint to toothpaste.The mine’s maintenance team was struggling with repeated breakdowns of the conveyor’s existing mechanical drive system, costing the mine up to 1 million Norwegian Kroner ($120,000) in lost production each time. Breakdowns peaked during the harsh winter of 2010 to 2011. “The capacity was not good enough, and the reliability was not good enough,” says Knut Petter Netland, Titania’s Mine Manager. “Several times a year we had a breakdown and the repair time was too long. We had to close the milling operation before we could start the mining operation again. It was an unacceptable situation.”Titania turned to original equipment manufacturer Kellve Sweden AB for help. After dismissing an electrical option due to cost, the Kellve team suggested a mechanical solution, ABB’s Dodge controlled start transmission (CST) drive system. The CST is a 2 in 1 gearbox that combines a planetary gear reducer with an integral wet clutch system. When coupled to an AC induction motor, the CST converts the motors high-speed, low-torque input to a low-speed, high-torque output, delivering smooth control and enough power to drive the largest and longest conveyors.Although there are over 3,000 CST installations around the world, this was Europe’s first. Bent Haaland, Titania’s Project Leader contacted two mines in the USA to gauge their experiences. “The feedback we got from them was very positive,” says Haaland. “They didn’t have any incidents or plant stops. So they really reassured us with claims of 98% availability and extremely low overall maintenance costs.”Installed in August of 2014, the CSTs have delivered the reliability that the Titania mining team was looking for. While it may have been a leap of faith choosing technology they hadn’t heard of before, in the end, they all agree it was the right decision. “While it’s not always a good thing to be Europe’s first, when it is backed by a well-known name like ABB, you know you can trust them,” says Netland. “And so far that trust has paid off. The reliability has been good.” Those sentiments have been echoed by Titania’s deputy leader for mine maintenance, Stig Olsen. “For me it’s big, it’s strong, it seems to run and run and run,” says Olsen. “The solution is robust, it’s reliable and it brings lower maintenance.”last_img read more

Liebherr autonomous trucks to adopt ASIs MOBIUS platformLiebherr autonomous trucks to adopt ASIs MOBIUS platform

first_imgAutonomous Solutions, Inc (ASI) and Liebherr Mining Equipment Newport News Co (Liebherr) have announced that Liebherr’s new autonomous ready haul trucks will be compatible with ASI’s autonomous command and control platform, MOBIUS. Liebherr’s vision of an autonomous haul truck includes an open interface that enables the truck to integrate to ASI’s Mobius platform. Liebherr’s autonomous vehicles can be controlled under an OEM agnostic command system for autonomous vehicles, providing maximum flexibility for their customers.“By adopting the Mobius platform, Liebherr is poised to differentiate its autonomous vehicles by addressing the market need for interoperability and openness,” explains ASI’s Drew Larsen, Director of Business Development over Mining. “I believe the market will welcome Liebherr’s decision.”Liebherr has integrated with the Mobius protocols for its vehicle control interface, rather than establishing a proprietary command and control platform on its own. This move to an open platform will provide much needed flexibility to their customers when integrating different autonomous vehicle types throughout a mine site.Liebherr stated:last_img read more

Patrick Eilert goes home to AJAX after six years in ASOBALPatrick Eilert goes home to AJAX after six years in ASOBAL

AJAX KobenhavnPatrick Eilert ← Previous Story VIDEO: Pascual and Co. present historical seven trophies Next Story → SG BBM Bietigheim “lost” goalkeeper with EHF CL experience – Ivan Stevanovic The new reinforcement of the Danish team AJAX Kobenhavn is the experienced domestic right back Patrick Eilert (26) who decided to finish his career in Spanish ASOBAL after six seasons there. The 205 cm tall lefthander left Naturhouse La Rioja, the team from Logrono with whom he won the second place in the Championship last season.However, the lights of the EHF Champions League don’t look enough attractive for the Danish guy who wanted to come back home and focus also on studies and some hobbies.– We are in AJAX Copenhagen incredibly happy – and proud – that we have managed to add a profile as Patrick Lykke Eilert team – says Ajax sporting director Ole Christensen, writes hbold.dk.Eilert played for Ciudad Real, Torrevieja and BM Valladolid before he joined La Rioja. read more
