The Importance of Pneumatic Rock Drills
Pneumatic rock drills continue to play a critical role in underground mining operations around the world. Despite advances in mechanization, compressed-air tools remain essential in narrow-vein, selective, and development mining where flexibility, reliability, and operator control matter most. A well-rounded pneumatic product line allows mining teams to handle everything from drifting and stoping to ground support with proven, serviceable equipment.
At the core of many underground operations is the CANUN 260B Jackleg Drill. Designed for horizontal and slightly upward drilling, jacklegs are widely used in development headings and narrow-vein mining. CANUN’s 260B Jackleg offers a balance of power and durability, making it a staple for mines that still rely on handheld drilling.
Vertical and overhead drilling demands a different solution, which is where the 260B Stoper Drill comes in. Stopers are essential for drilling upward holes, raise work, and production stoping in underground mines. A reliable stoper like CANUN’s 260B Stoper helps ensure consistent hole alignment and depth, even in demanding ground conditions. Its design emphasizes stability, airflow efficiency, and operator comfort.

For applications requiring downward or angled drilling without a leg feed, the 260B Sinker Drill fills an important niche. Sinkers, also known as Pluggers, are commonly used in benching, drifting, and utility work where portability is key. The 260B Sinker provides the same robust pneumatic performance as the jackleg version but in a compact configuration that is easier to maneuver in tight spaces.
Beyond underground mining, pneumatic drills are still widely used in surface applications. CANUN's 260B Quarry Drill is built for heavy-duty work such as bench drilling and secondary breaking. While sharing core components with underground models, quarry drills are optimized for durability and sustained output in open environments.
A complete pneumatic lineup goes beyond drilling alone. Ground support is just as critical. Tools like CANUN's CANPUSH51 Screen Pusher are part of the picture. Screen pushers enable safer and more efficient installation of mesh and ground support in underground headings. This reduces manual handling and improves overall safety conditions.
