Developing drill rigs for remote locations
Mar 2012
Atlas Copco New Release
- Atlas Copco has added a new multi-purpose drill rig for tunnelling and mining operations in remote regions.
- The new Boomer E1 C-DH is one of the largest diesel-hydraulics rigs on the market, with a reach of up to 95m2, a 38% improvement over its predecessor, the L1 C-DH.
-
Boomer E1 C-DH can operate in remote areas
- It is specially designed and construction sites lacking water and electrical infrastructure and comes with dual onboard 450 litre water tanks and a six-cylinder 232HP diesel engine to drive the rig, its boom and the drill's hydraulic pumps.
- Johan Jonsson, Product Manager for Atlas Copco Underground Rock Excavation, said: "In the case of a new project, the Atlas Copco Boomer E1 C-DH drill rig can be used to get started even before water and electricity are installed at the job site."
- Jonsson also pointed to the new drill rig's advantages in widening existing tunnels or adding bolts in older workings, as it is not necessary to install power and water infrastructure to support the rig on site.
- The multipurpose capabilities of the new rig are enhanced with the addition of the optional basket attachment. This allows the Boomer E1 C-DH rig to be used as a bolting rig and as a utility rig for drilling holes and installing ventilation ducting, among other tasks.
- The Boomer E1 C-DH drill rig comes standard with Atlas Copco's Rig Control System (RCS) with the option to upgrade to an even higher degree of automation. Jonsson said: "As a member of the Atlas Copco Boomer E-series of face-drilling rigs, the new rig has access to the wide range of existing options for that established product family."
- The new drill rig comes with a COP 1638, COP 1838, or COP 2238 rock drill with a dual-damping system for optimum service life. The BUT 45 heavy-duty boom is fitted, and it comes with a 2.5m boom extension and 1.8m feed extension. The new Boomer rig also has a BMH 6000 series hydraulic feed.
- The Boomer E1C-DH was developed alongside Scandinavian contractor Veidekke, based on their request for a diesel hydraulic driven rig with large coverage area combined with a service basket. The first rig has been used in various projects since delivery, including after bolting and for constructing cross cuts in existing tunnels.

Boltec EC with new BUT 45 boom
- Also added to Atlas Copco's extensive range of products is the new Boltec EC, equipped with the new BUT 45 boom, a fully mechanised bolting unit based on Atlas Copco's existing bolting platform.
- The unit provides for precise installation in lengths of 1.5-1.6m and at heights up to 13.5m. It is built on an articulated 4-wheel drive carrier and is equipped with the new BUT 45 heavy duty boom for direct, fast and accurate positioning between holes. The feed rotary unit features double rotation in the range of 190 degrees feed roll-over and 135 degrees feed rotation.
- Designed for a hole range of 35-64mm, the rig is equipped with the COP 1435 rock drill, providing up to 30 per cent higher penetration rates than the already successful COP 1132.
- Boltec operator Markku Paakkolanvaara said: "I have used Boltec rigs for about five years and now I have been working with the new rig for about three weeks. The boom feels much steadier and also gives a much better reach." Among other tasks, the rig has been used to drill holes for power lines and water pipes and has installed some 3,600 bolts at an average rate of 120–130 bolts per shift.
