Joao Felix scores twice as Atleti see off Juve

first_imgJoao Felix showed why Atletico Madrid were happy to pay €126million to sign him with a hand in both goals as the Rojiblancos beat Juventus 2-1 in the International Champions Cup.In a repeat of last season’s thrilling Champions League round-of-16 tie that Juventus won 3-2 on aggregate, Atletico took a measure of revenge in an entertaining encounter at the Friends Arena in Stockholm, where Thomas Lemar turned Joao Felix’s volley into the net to give Diego Simeone’s men the lead.The pair combined again for Atleti’s second, which was scored by teenage sensation Joao Felix, whose performance full of energy and flair will have delighted his coach.

The result rounded off a satisfying pre-season for Atletico, who beat rivals Real Madrid 7-3 earlier in the ICC, while Juve coach Maurizio Sarri gave Paulo Dybala a run out after his mooted move away from the club failed to transpire.PureTalent— Atlético de Madrid (@atletienglish) August 10, 2019Giorgio Chiellini’s close-range volley was turned over the bar by Jan Oblak, who got down well to make a one-handed save, and Cristiano Ronaldo fired over the crossbar from the edge of the box as Juventus enjoyed a positive start.But Atletico punished the Bianconeri’s wastefulness after 23 minutes when Joao Felix met Kieran Trippier’s cross with a side-footed volley that deflected off Lemar’s thigh on its way past Wojciech Szczesny and into the net.The lead lasted just six minutes as Khedira capitalised on some hesitant Atletico defending and sent a low drive into the bottom corner of Oblak’s net, with Douglas Costa’s step-over helping to distract the goalkeeper.Lemar returned the favour to Joao Felix just after the half hour, floating a weighted pass into the box where the teenage forward slid in ahead of Matthijs de Ligt to score with a half-volley from 12 yards.After Costa hit the outside of the post with a low drive early in the second half, Adrien Rabiot went even closer, crashing a thunderous effort against the upright from 20 yards.Mario Mandzukic played in Dybala for a chance in the box 13 minutes from time but his deflected shot was saved at full stretch by Oblak, meaning Atletico entered the new season on a winning note. read morelast_img read more

Codelco to test Aker Wirth Mobile Tunnel Miner at Chuquicamata Underground

first_imgAker Wirth and Codelco, the world’s largest producer of copper, signed a contract at the end of 2012 on the delivery and testing of a Mobile Tunnel Miner (MTM). The machine will be tested from mid-2014 in the Chuquicamata mine in Chile where the underground mining of copper is planned for the future. The Aker Wirth MTM will bore a network of tunnels in the Chuquicamata mine in preparation for the later mining of rock containing copper.“Previously, tunnels of this type were blasted out of the rock in copper mines”, said Ulrich Frenzle, Vice President Mining & Construction at Aker Wirth. “These will be created mechanically for the first time with the MTM4, thus improving tunneling efficiency and safety in the mine significantly.” The machine will also need to cut tight curves with an exact profile for this purpose, an operation which is particularly demanding on the manoeuvrability and precision of the machine.The Mobile Tunnel Miner combines the flexibility of a roadheader with the robustness of a tunnel boring machine. The self-propelled machine excavates rock with four powerful hydraulically actuated arms fitted with disc cutters. The muck is conveyed to the rear of the machine by a loading apron with loading disks and via a chain conveyor where it is loaded. In addition to circular cross sections like those achieved with a tunnel boring machine, the Mobile Tunnel Miner can also cut rectangular and horseshoe-shaped or semi-rectangular tunnels with a bore diameter of up to 6 m. Thanks to swivel joints in the machine, the turning radius of the 40 m long MTM4 is only 12 m, meaning it is “ideally adapted” to the demands of the Chilean copper mine, say Aker Wirth. The Mobile Tunnel Miner is also innovative in terms of its mobility, as it can move forward flexibly using a walking mechanism and backward with a crawler. A positioning control system ensures that the machine is always precisely aligned. “We expect to set new standards in mine development with the MTM. Its development fully reflected quantifiable customer benefits and safety issues”, says Frenzle with conviction. “When compared to drill and blast, which up until now was the usual method employed in rock of this hardness, the MTM4 shall be able to tunnel up to 12 m a day, thus more than doubling the current performance.”The machine operates with special undercutting technology and, is designed for especially efficient tunneling in hard rock. It also cuts extremely precise tunnel profiles, considerably reducing the efforts for tunnel fortification. “Depending on project conditions, costs for tunneling are more than 30 % less than for drill and blast”, summarises Frenzle. Another advantage over drill and blast is that the MTM requires considerably less work from personnel at the tunnel face. The MTM is operated from a central control cabin on the machine itself. A high degree of automation minimises contact between personnel and both moving components and rock. Thanks to its flexibility, the MTM can be easily driven away from the tunnel face for maintenance purposes, and this also contributes to the safety of operating personnel.last_img read more
