The Boomer M1 L has been specially designed for development and production applications in low seam mines with roof heights of 2.2–2.5 m.
The rig itself has a height of 1.8 m and is believed to be the most robust of its kind on the market featuring a stronger carrier and oversized wheels compared to similar rigs in this range.
Peter Bray, Product Manager, explains: “This is the perfect machine for the rough and tough environment of room and pillar mining and especially where there are long distances to be covered, typically six to twelve kilometers per day.
“It is very strong with components that can withstand all the wear and tear of tramming on rough roadways, but it also makes life much easier and more comfortable for the operator.”
The Boomer M1 L is spacious and visibility is excellent from the fully enclosed air conditioned cabin, providing extra safety and comfort.
Bray explains that the Atlas Copco designers have “married together” existing components and systems from drill rigs such as the Boomer S1 L and the Boomer T1 D in order to meet demands for a stronger workhorse in low roof applications.
The rig has an improved flexible boom, simple controls (Direct Control System 2, DCS 2,) and a choice of rock drills – COP 1638 or COP 1838. It is also designed to be extremely easy to service as a means of keeping downtime to a minimum.
In addition, the improved environment inside the cabin is matched by the low emission Deutz TCD2012 L04 80kW Tier 3 engine.
The prototype was successfully tested by the Polish mining company KGHM in the Rudna Mine after which KGHM placed orders for several Boomer M1 L rigs.
