Atlas Copco’s newest single-boom face drilling rig is designed for development and production drilling in low- to medium-height mines, including applications with extensive tramming. With a machine height of 5.9 ft (1.8 m), the Boomer M1 L is sized for room-and-pillar mines with back heights from 7.2 to 8.2 ft (2.2 to 2.5 m).
The rig’s carrier features heavy-duty axles and a reinforced articulation section as well as oversized wheels compared with similar rigs in the range. According to the company, components and systems from existing drill rigs such as the Boomer S1 L and the Boomer M2 D were incorporated into the design of the Boomer M1 L to respond to customer demand for a more robust single-boom face drilling rig for low height applications.
The Boomer M1 L also features a fully enclosed, air-conditioned cabin, and an ergonomic control panel, contributing to operator safety and comfort. Power is provided by a Deutz 80-kW (107-hp) Tier 3 engine. Additional design highlights include an improved flexible boom, simple controls (Direct Control System 2), as well as a choice of COP 1638 or COP 1838 rock drills. The rig is designed to be easy to service, with easily accessible service points behind protective hatches.
Atlas Copco said a prototype of the Boomer M1 L was successfully tested by the Polish mining company KGHM which has since placed orders for several units. www.atlascopco.com
