Feature Hot Products and High Tech Were the Highlights at this Year's MINExpo Show. By Mark S. Kuhar and Josephine Smith INExpo 2012, held every four years, concluded a historic run at the Las Vegas Convention Center in September, amassing approx‐ imately 850,000 sq. ft. of exhibit space, up 42 percent from its previous high in 2008; and an estimated 50,000 atten‐ dees, up about 30 percent from 38,000, four years ago. Here are some of the products that Rock Products saw on the show floor. Atlas Copco Atlas Copco introduced the Pit Viper 311 wide‐range rotary blasthole drill to the world at MINExpo 2012. The PV‐ 311 is designed to meet the demands of today's expanding mining market with the proven systems, components and technology of the Pit Viper series. The Pit Viper 311 is similar to the Pit Viper 351 with its single‐pass drilling but the Pit Viper 311 has the capacity to drill holes deeper to a maximum depth of 125 ft. (38.1 m). Drilling up to 65‐ft. (19.8‐m) clean holes with a live tower can reduce non‐drilling time and, combined with taller benches, can greatly increase production capability. The Pit Viper 311 is the first release of the all new Pit Viper 310 series. Atlas Copco Engineering Project Manager Iain Peebles said the PV‐311 offers a narrow range of hole sizes 9 to 12.25 in., which fills in the gap between the hole ranges of the Pit Viper 351 and the Pit Viper 270. "We've incorporated a lot of existing 18 ROCKproducts • NOVEMBER 2012 BEST OF SHOW M technology that's proven successful on our other Pit Viper models," Peebles said, adding that there have been some upgrades. "One of the things we're most excited about on the PV‐310 se‐ ries project is our new cab. Now you have a fully adjustable chair with joy‐ stick and cab controls. We've elevated the cab above the deck to give the op‐ erator a better view." The Pit Viper 311 offers drive train options with both Tier 4 and Tier 2 diesel engine alternatives. The tower has an interchangeable unit, struc‐ turally similar to the Pit Viper 351, but is deeper to accommodate larger sheaves for either single‐pass or multi‐pass applications. Weldments have also been improved, including a ladder that provides access to decking in the tower above the rod changer when the tower is horizontal. Bits can be changed above the Pit Viper 311 rig's deck even while single‐pass drilling 65‐ft.‐deep (19.8‐m‐deep) holes so operators will have their eyes on making and breaking the connec‐ tion each and every time. Atlas Copco, www. Boart Longyear Boart Longyear showed the 10UMX bit, the latest addition to the Ultramatrix (UMX) family of diamond coring bits. The 10UMX is a high‐performance dia‐ mond coring bit with the freest‐cutting matrix available, enabling the bit to penetrate the very hardest rock forma‐ tions in extreme conditions. "The 10UMX diamond coring bit com‐ pletes the product range for our award‐winning family of UMX bits, pro‐ viding a bit for any type of ground con‐ dition encountered," said Matt Baird, global product manager for Boart Longyear. "We have tested these bits in all regions of the globe and take great pride in providing drillers the most ad‐ vanced line of diamond bits in the in‐ dustry to maximize their productivity." UMX bits are engineered to outperform existing bit technology in a wide range of drilling conditions and ground for‐ mations. UMX bits use advanced metal‐ lurgical formulas to provide increased penetration capabilities, turning easily from one ground formation to another. The optimized life of the UMX bits translates to less tripping and in‐
