Low-profile Face Drilling Rig is Built for Heavy Tramming

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 exten-sive 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 rein-forced articulation section as well as over-sized wheels compared with similar rigs in the range. According to the company, com-ponents 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 pro-vided 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.
