Tough times, but prepare for the upturn! been forced into mining more difficult resources as the easily available ones have been stripped. This means digging deeper into the earth which is more expensive, dangerous and time consuming. In addition to the tough tasks of drilling and extraction, the mining industry is confronted with other challenges such as the impact of their operations on the environment, increased regulations and the rising costs of mining. Mining companies are clearly doing their best to manage productivity and improve efficiencies, and at Atlas Copco we have an important role...

New exploration rig makes grade control easy and safe The largest pure gold mine in northern Europe, Björkdalsgruvan, expects continued strong demand and is gearing up for future production using the new, compact Explorac 100 drill rig. Mining & Construction – 2 / 2013

Compact yet mighty: The new Explorac 100 performs RC drilling at Sweden’s Björkdalsgruvan, the largest pure gold mine in Northern Europe. The rig’s automatic rod handling system and teleremote control panel keep drillers out of harm’s way. hether in good or bad times, few global commodities capture the imagination like gold. And despite the drop in prices this year, mines are expecting demand to remain stable. Among the mines whose operations are thriving is the Bjorkdal mine, or Björkdalsgruvan as it is known locally, tucked away in the deep forests of northern Sweden some 40 km northwest of...

These are carefully collected in bags, separated into boxes according to a numbering system and delivered to the company’s onsite geologist before being sent on for further analysis. Identical samples A crucial part of the operation is to achieve near-identical samples. These should pre­ ferably weigh 2.5 kg for accurate analysis. According to Andreas Hansson who oper­ ates the Explorac...

>>>>> Products & progress >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> COP 4038 The fastest rock drill ever made! tlas Copco has launched the world’s fastest rock drill. Called COP 4038, this 40 kW machine operates at a frequency of 140 Hz compared with the 117 Hz of the COP 3038. Designed for tunneling and drifting in the hole range 43–64 mm, the COP 4038 is an extremely advanced unit. High frequency technology is utilized so that instead of simply striking the drill steel harder, the piston strikes at a higher frequency, resulting...

AT LAST! A new subway line for the Big Apple They’ve waited patiently for almost a century, but now, at long last, New Yorkers are to get a new subway extension that will ease overcrowding and congestion on the city’s transport system. M&C goes beneath the streets of The Big Apple to meet the tunnelers working on the first stage of the new Second Avenue line.

Tough challenge below the streets of Manhattan It has been described as the most complex subway project in the world in the heart of one of the most densely populated cities on the planet. New York’s long-awaited Second Avenue extension is all that and more. A major challenge: Workers set up the compact FlexiROC T30 in the access shaft at the north end of the 86th Street project. ew York’s long awaited Second Avenue subway extension is now well under way on Manhattan’s East Side and will be a welcome addition to the city’s mass transit system. The first decision to build the new line was taken...

Benching the North Shaft: A Boomer T1 D had to be used to expand the lower level of the shaft to create sufficient space for the Boomer E2 C (above) to start vertical drilling. FIRST PHASE The route: The Second Avenue subway will run from 125 Street in East Harlem down to Hanover Square in the financial district and incorporate three new stations – at 96th, 86th and 72nd Streets. Scheduled to be opened in 2019, the new subway will reduce overcrowding and delays on the Lexington Avenue line, improving travel for both city and suburban commuter­ , and provide better access to mass transit s for...
