Top Hammer XL is the latest innovation in surface top hammer drilling from Sandvik Mining and Rock Solutions. The new drilling system, targeting large-scale quarry and surface mining customers, offers a fast, fuel-efficient and cost-effective way to drill holes 140 to 178 millimetres (5.5 to 7 inches) in diameter.

The components of the system – a new Pantera DP1600i drill rig, new RD1840C rock drill and new LT90 rock tools – are all optimized to work together in drilling.

The heart of the Top Hammer XL system lies in Sandviken, Sweden, and Tampere, Finland, where all the components have been designed and manufactured. They work together and provide smooth operation and a highly productive system with optimum drilling results.

“A key asset of the Top Hammer XL drilling system is that all three main components – the drill rig, rock drill and rock tools – have been reviewed, redesigned and mutually optimized,” says Jukka Siltanen, product line manager, rock drills at Sandvik Mining and Rock Solutions.

Efficiency

The efficiency of the new Top Hammer XL drilling system stems from the three components. The proven carrier offers a solid base for the extremely powerful rock drill that generates an optimum pulse for the effective tooling system, which in turn transfers the high-energy shock wave with minimum losses to the rock. The Top Hammer XL system has been thoroughly tested and proven in several field tests by drilling more than 100,000 meters in challenging rock conditions. The test results in the given conditions show a 50 per cent reduction in fuel consumption, 25 per cent reduction in total drilling costs and 15 per cent increase in productivity compared with the DTH drilling method.
