Rocket Boomer E-series rigs geared up for efficient tunnelling

To further enhance the success of Rocket Boomer E-series – Atlas Copco’s new series of face drilling rigs for medium to large tunnels – a number of options have been added to the list of features. The rig can now be delivered with the upgraded Tunnel Manager™ software, the Atlas Copco Tunnel Profiler and a new rod handling system, specially designed for the E-series.

 Rocket Boomer E-series can now be delivered with the upgraded Tunnel Manager™ software.
The introduction of the Rocket Boomer E-series has been a great success. With the new BUT 45 boom, the 3rd generation Rig Control System and the possibility to use the fastest rock drill in the world, COP 3038, it has been the first choice for customers demanding high productivity in drifting.
BUT 45 boom
The BUT 45 boom has a double rotation head for faster boom and feed movements when drilling the tunnel face. The rotation head also offers sideways boom rotation, which together with the higher bracing force ensures that the crosscuts and rock bolts drilled require few set-ups. More importantly, the increased boom stiffness permits longer boom extension and more accurate positioning, resulting in greater coverage area and reduced over- and underbreak. Optional equipment, such as the rod handling system, can be mounted onto the boom thanks to the higher carrying capacity.
Rod Handling System
The new Rod Handling System, RHS E, is developed solely for the E-series rigs and can accommodate eight 10 ft (3.05 m) extension rods. RHS E enables the drilling of longer holes, for grouting, probing or drainage, without manual rod extension. 

 Rocket Boomer E-series equipped with RHS E, Tunnel Manager™ software and Atlas Copco Tunnel Profiler.
Tunnel Manager
The Rocket Boomer E-series features the third generation Rig Control System, RCS3, which gives improved control of the drilling process and the boom and feed movements. When the rig is equipped with ABC Regular and Total, Atlas Copco now offers the facility to furnish it with the upgraded software Tunnel Manager, for creation, storage and analysis of vital tunnelling and drilling data. The software is available in three packages, whereof the most advanced package offers the possibility to analyze and translate data into rock mass characteristics such as rock hardness and fracturing.
Atlas Copco Tunnel Profiler
Another feature introduced at Bauma is the Atlas Copco Tunnel Profiler, a fully integrated 3D-scanning system telling the operator after just a few minutes of scanning how the excavation conforms to the pre-planned design. By using this system under- and overbreak and shotcrete thickness can be assessed and corrected at an early stage of the tunnelling cycle. 
All options considered, the new features of the Rocket Boomer E-series make the rigs even more geared up for accurate high speed drilling in civil engineering projects.
