BLASTHOLE DRILLS SEPTEMBER 2018 • E&MJ 33 www.e-mj.com the customer advances their automation integration." For example, the advanced "Compres- sor Management System (CMS) comes standard with this machine and saves thousands of gallons of fuel per year and will ultimately reduce your overall carbon footprint while extending maintenance intervals and prolonging the life of your compressor and engine" to "an estimat- ed 30K hours," Ewanow said. "Advanced troubleshooting via the controls system helps you identify many problems before you pick up a wrench, and the patented deck wrench allows bit change with no bit basket handling." Ewanow described the modules as "easy to use and understand." Those descriptors are the hard-earned result of dedicated research, he said. "The chal- lenge has been to offer the features that provide customer value and not overcom- plicate the control logic," he said. "Un- derstanding the appropriate user inter- face experience was paramount." Intelligent and powerful, the rig offers "greater flexibility than do tethered elec- tric drills," Ewanow said. At the same time, Sandvik released new literature on the DR412i, a rota- ry blasthole rig, which first launched in 2015 and is currently operating in mines in North America, South Africa and Aus- tralia. The upgraded rig is ideal for "me- dium to larger" mines and "progressive contractors who want to provide a differ- ent level of service to their customers," Ewanow said. The rig's intelligent control platform features "improved reliability, safety inter- locks and data collection," Ewanow said. Other listed upgrades include further au- tomation-readiness, down-the-hole (DTH) capability options, improved serviceabil- ity and accessibility via the 360° catwalk system, an ergonomic cab with enhanced arm rest-mounted joy stick controls, superb visibility, and "in-cab control features like auto-pipe handling" to improve efficiency, Ewanow said. The rig allows the customer to deter- mine the level of automation with the option to eventually upgrade incremen- tally. "We offer our unbundled automa- tion modules, so customer can pick and choose what features work with their sys- tem integration," Ewanow said. "We also offer an open platform, so data can be shared with other systems via our Opti- mine application." That means Sandvik does not "charge the customer for their data as other companies do," he said. The rig "is designed for rotary and DTH drilling applications with a hole diameter range of 216 m to 311 mm," Sandvik re- ported. "High- and low-pressure versions are available with single-pass maximum hole depth of 31 m and multipass max- imum hole depth of 75 m." It is built to deliver "reliability while bringing a new level of safety and productivity to any op- eration," the company reported. The optional CMS can save fuel, re- duce carbon footprint, and extend main- tenance intervals, Ewanow said. The company described the rig as ca- pable of delivering "dependable penetra- tion in the world's harshest mining con- ditions." Ewanow said that, as with the DR416i, this is due to the rig's heavy-du- ty feed chains and rotary head. "With a higher rotary power and bit loads com- pared to competitive models, the DR412i delivers greater penetration at lower oper- ating costs," he said. Field results prove it, Ewanow said. "We outperformed competitive units with improved penetration," he said. "We offered greater bit load and rotary power with proper flushing air to burn less fuel overall."
