Multi-purpose Drilling Rig for Mining and Tunneling
Atlas Copco’s new Boomer E1 C-DH face drilling rig is a single-boom, diesel-hydraulic multipurpose unit specifically designed for mine areas lacking water and electrical infrastructure. The Boomer E1 C-DH comes with dual onboard 118-gal (446-liter) water tanks and a six-cylinder, 232-hp (173-kW) Deutz diesel engine to drive the rig, its boom and the drill’s hydraulic pumps. The E1 C-DH is one of the largest diesel-hydraulic face-drilling rigs on the market, with a coverage area of up to 1,022 ft2(95 m 2 )—a 38% improve-ment over its predecessor. The multipur-pose capabilities of the new machine are enhanced with the addition of an optional basket attachment. This allows the rig to be used as a bolter and as a utility rig for drilling holes and installing ventilation ducting, among other tasks. The Boomer E1 C-DH drill rig is equipped with Atlas Copco’s Rig Control System with the option to upgrade to an even higher degree of automation. The rig also can be ordered with COP 1638, COP 1838 or COP 2238 rock drills with a dual-damping system for optimum service life. The BUT 45 heavy-duty boom is equipped with a double-rotation unit for plus/minus 190° feed roll-over and plus/minus 135° feed rota-tion. It comes with an 8-ft (2.4-m) boom extension, 5.9-ft (1.8-m) feed extension and a BMH 6000 series hydraulic feed.
