Australian mining contractor Byrnecut set a new world underground drilling record of 58,318 drill metres in July at Newmont’s Jundee gold mine in Western Australia.
Byrnecut has achieved this using a Tamrock Axera D07S-260 drilling unit from Sandvik Mining and Construction Australia.
Byrnecut general manager Barry Upton says that in addition to setting a new world drilled meter record, the Axera D07S-260 jumbo, operated by Pat Heron, Derek Walker and Carl Mlinaric, was responsible for 898m of advance in July.
“This sort of performance is why we use the Tamrock Axera; it’s simply the best drill unit in the business,” Upton says.
The Tamrock Axera D07 is a twin-boom electro-hydraulic drilling jumbo that can develop headings up to 60m2.
The twin TB60 booms deliver 18 to 22kW of power to the rock drill units, which can crosscut, drift and bolt hole drill.
“For Byrnecut, our goal is to maximise productivity. We need equipment that is safe, tough, reliable and easily serviceable.
“The Tamrock Axera meets all those criteria and delivers performance that gives us a competitive edge,” Upton says.
Sandvik Mining and Construction account manager Chris Noden congratulates Newmont and Byrnecut.
“It certainly pleases me to know the record was broken by one of our Axera drills,” Noden says.
“The Tamrock Axera D07 is one of the most reliable and productive drilling units in the Australian underground mining market and continue to set new benchmarks for reliability, performance and productivity,” he says.
The four-wheel drive centre-articulated carrier ensures optimum manoeuvrability, good balance and safe tramming speed of up to 7.2kph.
Noden says the Axera D07 offers easy access for maintenance and mobility, noise and vibration insulation, built-in diagnostics, ergonomic cabin and instrument design and a range of innovative safety features.
“Byrnecut has used the Axera D07 for many years and I’m pleased to say they remain very happy with their purchase. For Byrnecut its all about operator safety, reliability and productivity,” Noden says.
Sandvik employs 350 people in Australia.
