The newT-WiZ drill string, with its combinationof T-WiZ Speedrods and T-WiZ shankadapters, offers up to 30 per cent longerservice life resulting in fewer rod changesand more productivity per shift.T-WiZ claims to be the toughest systemon the market thanks to its greater threadstability and is robust enough to preventproduct breakage in the blast hole. Thisputs an end to time-consuming rod andshank changes and helps to keep stock low.Regardless of the assignment – whetherit be underground, in surface mines or onconstruction sites – T-WiZ makes a substantialdifference in tough formations andfractured rock.The increased capacity provided byT-WiZ – in other words, more holes pershift – also paves the way for faster blastingand a more rapid advance.There are three dimensions to choosefrom – T38-WiZ, T45-WiZ and T51-WiZSpeedrods and shank adapters designed forextension or drifting drill strings. In addition,these systems are all perfectly matchedto the comprehensive range of Secoroctophammer bits.

Yalin says the rig is meeting expectationsand adds: “Compared to the localbrands in China, this rig works faster and ismore reliable.”York Yang, Atlas Copco’s Product Managerin Nanjing, explains: “This is our first semihydraulicrig series and it represents a newconcept compared with purely pneumaticdrill rigs, focusing on maximum performance,high fuel efficiency and low initial investment.Right now it is intended only for China but weare investing in the worldwide potential.”Designed to drill 92-127 mm holes to amaximum depth of 35 m, the AirROC D45 SHrig’s low fuel consumption and high penetrationrate is thanks to a combination of AtlasCopco’s reputable portable compressorand DTH hammer, coupled with the reliablehydraulic control system.Ergonomically designed to give the operatora comfortable working environment, therig offers good visibility and serviceability andhas controls at the rear as well as at the side,enabling the operator to stand on the rig whiletramming.16 Mining & Construction – 3 / 2011
Make way for Boomer M1 LNew single boom rig for a rough, tough worldLow and robust: The new Boomer M1 L is specially designed for room and pillar mineswith roof heights of 2.2 – 2.5 m. Strength and ease of service are two clear plus points.A new single boom face drilling rig from Atlas Copco for low-to-medium heightmines combines extreme robustness with operator comfort.The Boomer M1 L has been speciallydesigned for development andproductio n applications in low seammines with roof heights of 2.2–2.5 m.The rig itself has a height of 1.8 m andis believed to be the most robust of its kindon the market featuring a stronger carrierand oversized wheels compared to similarrigs in this range.Peter Bray, Product Manager, explains:“This is the perfect machine for the roughand tough environment of room and pilla rmining and especially where there arelong distances to be covered, typicallysix to twelve kilometers per day.“It is very strong with components that canwithstand all the wear and tear of tramming onrough roadways, but it also makes life mucheasier and more comfortable for the operator.”The Boomer M1 L is spacious andvisibilit y is excellent from the fully enclosedair conditioned cabin, providing extra safetyand comfort.Bray explains that the Atlas Copcodesigners have “married together”existin g components and systems fromdrill rigs such as the Boomer S1 L and theBoomer T1 D in order to meet demandsfor a stronge r workhorse in low roofapplications.The rig has an improved flexible boom,simple controls (Direct Control System2, DCS 2,) and a choice of rock drills –CO P 1638 or COP 1838. It is also designedto be extremely easy to service as a meansof keeping downtime to a minimum.In addition, the improved environmentinside the cabin is matched by the lowemission Deutz TCD2012 L04 80kW Tier 3engine.The prototype was successfully tested bythe Polish mining company KGHM in theRudna Mine after which KGHM placedorders for several Boomer M1 L rigs.Footnote: See the new Boomer M1 L in action onYouTube, www.youtube.com/AtlasCopcoUGMining & Construction – 3 / 2011 17
