Atlas Copco has introduced a new face drilling rig for narrow drifts . Based on its well-proven predecessor, the Boomer 104, the new Boomer T1 D offers an impressive array of technical and environmental improvements. Similarly, Atlas Copco associate, Aramine has a new range of narrow vein machines, described in the October issue of International Mining. Narrow drifts or tunnels call for a small and flexible face drilling rig. Since the 1990s, Atlas Copco has filled this role with the Boomer 104. Now Atlas Copco has launched its successor – the Boomer T1 D. This retains the features and capabilities of the well-liked Boomer 104, but now introduces an extensive range of improvements and upgrades, all aimed at improving productivity, safety and operator comfort.The improvements and options include a more powerful and cleaner Tier 3 engine for higher tramming speed and environmental benefits. The boom suspension system reduces stress on the machine, thereby increasing service life and improving operator comfort when driving. A more ergonomic and comfortable cabin with better visibility is an optional extra, and the serviceability has been improved with more accessible service points.The new carrier frame is stronger, has a lower centre of gravity and has an oversized articulation to cope with demanding operating conditions.The first Boomer T1 D was tested at the Lovisa lead/zinc mine in Sweden where it achieved good results compared to the mine’s previous Boomer 104. Operators of the machine praised the improved ergonomics and drilling performance during the trial, Atlas Copco says.
