But then, that’s just what you would expect from the company producing the hammer used to successfully drill the first supply holes to reach the trapped Chilean miners back in 2010! Where others failed, the Mincon Hammer succeeded at the first pass.
The President of Chile was rather reluctant to let Mincon have the hammer back and insisted that it should take pride and place in a glass case in the Presidential Palace. That’s exactly how Barry Carson of Blasting Services feels about his Mincon 4HDS hammer.
Most hammers will achieve a life expectancy of between 20,000 and 40,000 metres, dependent upon ground conditions and good drilling and maintenance practices. Barry’s hammer managed a total of 96,500 metres over its lifetime, drilling in challenging conditions in North Wales and maintaining top performance throughout.
The professionalism of Blasting Services driller Barry Carson, with good service practice and selective rebuild enabled the hammer to clock up this impressive life achievement. “It’s no surprise to me,” he stated. “We’ve been using Mincon Hammers from Rock Drill Engineering for over seven years, and they’re all impressive performers! Although we have used other products, we know from experience that these offer better levels of performance and reliability.”
Rock Drill are not too surprised by the performance of this unit, although they haven’t seen one before with a documented history to prove the achievement. “Many of the hammers we supply reach totals well beyond those normally expected within the industry,” said MD Steven Beasley. “We supply a well designed, professionally built product that we know will perform consistently beyond the norm, but it’s also down to the skill and experience of the driller and the care taken to keep the hammer in top condition. Simple maintenance and proper lubrication with selective rebuilds will ensure top performance and extend the projected life span to provide very acceptable overall operating costs.”
Blasting Services acknowledge that they receive excellent levels of aftercare from Rock Drill, who also service their DTH hammers. “It’s not unusual for Rock Drill to provide a 24 hour turnaround on hammer service to support our drilling activities if ever we need it,” stated Ian Knott, Head of UK Operations.
Barry Carson’s hammer clearly illustrates the savings that can be made when combining a world class product with expert operation and proper care in service to achieve the optimum with this robust equipment.
