70 E&MJ • MAY 2019 www.e-mj.com SUPPLIERS REPORT Codelco adopted Sandvik's AutoMine and OptiMine solutions as a production automation system for Chuquicamata Underground. The system will allow Codelco to op- erate its new fleet of Sandvik LH621 loaders in full automation. It will inte- grate manual operations and autonomous equipment and will enable full transpar- ency and real-time control over the par- allel production and mine development activities, Sandvik reported. Codelco described the system as crit- ical to improving efficiency and safety. "Using our mines to full effect is part of our focus on sustainability and a key driv- er for our business," Andrés Avendaño, operations manager, Chuquicamata Un- derground, said. AutoMine covers all aspects of auto- mation, Sandvik reported. OptiMine in- tegrates all relevant process and produc- tion data into one source for real-time analysis. New OptiMine features show- cased at Goldcorp's recent #DisruptMin- ing event included location-based ana- lytics, smart scheduler, and enhanced 3D mine visualization. Codelco, the world's biggest copper producer by total output, is converting Chuquicamata from open cast to an un- derground mine as part of a 10-year stra- tegic mine-expansion project. Operations are due to start this year. Codelco adopted the AutoMine Load- ing system for the El Teniente copper mine in 2004. Separately, Sandvik reported it ac- quired Newtrax, a wireless connectivity and IoT solutions supplier. The partnership should benefit cus- tomers deploying or seeking to adopt OptiMine, Sandvik reported. "By includ- ing Newtrax into the Sandvik family, we further strengthen our leading position in areas related to automation and digitali- zation," Henrik Ager, president, Mining and Rock Technology, Sandvik, said. Newtrax, headquartered in Montréal, Canada, and employing 120 employees, will operate as an independent business unit within the division Rock Drills and Technologies in the area Mining and Rock Technology, Sandvik reported. The deal was calendared to close in Q2 2019. 690 MT Rock Crusher Moved Mammoet moved a 690-metric-ton (mt) granite rock crusher and primary conveyor inside the A.R. Wilson Quarry in Aromas, California, USA. Both pieces of equip- ment needed to be relocated from the top of the quarry to the new location downhill and 1,200 meters (m) away. Owner Graniterock previously at- tempted to drive the rock crusher, Mam- moet reported. The crusher experienced a loss of braking power and the oper- ation could not be completed safely. Mammoet proposed to move the crush- er in one piece on SPMTs and received the contract. The route included an intermittent 8%-10% grade and, after several days of rain, mud. The 152-m primary conveyor, broken down into four sections, went first. The rock crusher followed, with a total Chuqui Underground Adopts Sandvik Automation Solutions The system will allow Codelco to operate its new fleet of Sandvik LH621 loaders in full automation. A crusher is moved using a self-propelled modular transporter (SPMT).
