Pneumatic Rock Drills for Underground Mining: CANUN’s 260B Product Line

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 and quarry work 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. Our 260B Jackleg offers a balance of power, durability, and ease of maintenance, making it a staple for mines that still rely on handheld drilling. Its compatibility with standard steels and bits, combined with strong penetration rates, allows crews to stay productive without sacrificing control.

Vertical and overhead drilling demands a different solution, which is where the 260B Stoper Drill comes in. Stopers are essential for drilling upwards 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 - critical factors during extended drilling cycles.

For applications requiring downward or angled drilling without a leg feed, the 260B Sinker Drill fills an important niche. Sinkers 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 can be 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, which is why tools like our CANPUSH51 Screen Pusher are part of the picture. Screen pushers enable safer and more efficient installation of mesh and ground support in underground headings, reducing manual handling and improving overall safety conditions.

For mines operating in challenging geology or constrained headings, a comprehensive, field-proven pneumatic lineup, such as CANUN’s product line, remains a practical, dependable solution in modern underground mining.

As always, CANUN would like to remind drill users that we continue to provide full Spare Parts support for the S250 series. Our flagship CANUN 260B Rock Drills are fully interchangeable with the discontinued S250 model.

You can count on CANUN to keep your operations running smoothly.
