Self-sufficient drilling rig launched

Atlas Copco is aiming to improve tunnelling rates on projects without water and electricity supplies with the launch of the Boomer E1 C-DH face drilling rig. The rig is one of the largest diesel-hydraulic face-drilling rigs on the market, with a coverage area of up to 95m2, and also features an on-board 450litre water tank.

According to Atlas Copco Underground Rock Excavation product manager Johan Jonsson, the rig provides unique advantages. “In the case of a new project, the E1 C-DH drill rig can be used to get started even before water and electricity are installed at the job site,” he said.

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 E1 C-DH to be used as a bolting rig and as a utility rig for drilling holes and installing ventilation ducting, among other tasks.

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 equipped with a double-rotation unit for plus or minus 190 degree feed roll-over and plus or minus 135 degree feed rotation, providing the operator with fast and accurate positioning between holes. It comes with a 2.5m boom extension and 1.8m feed extension.
