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.
