Many mining crosscuts are too narrow for large drilling equipment. The S82 leg rock drill, engineered with a compact structure and agile handling, meets the exacting demands of such restricted spaces. This robust pneumatic drill combines a lightweight aluminum alloy body with a low-vibration design, allowing a single operator to position and drill quickly even on steep or curved walls. Its modular components—including a quick-change chuck and adjustable air valve—simplify operation: miners simply secure the drill, set the optimal pressure, and begin drilling with minimal setup time. The result is faster crosscut advancement and more efficient ventilation channel completion.

Before introducing the S82, mines relying on bulkier drills faced constant delays in narrow tunnels. Crews often had to widen passages prematurely or resort to manual drilling, slowing progress and increasing labor costs. After switching to the S82, operators report a 40% reduction in drilling time per crosscut and greater maneuverability around obstacles. Ventilation holes that once took hours now reach target depths in consistent, rapid cycles. The drill’s lower air consumption has also reduced energy costs per meter drilled.

We are a dedicated rock machinery factory with over three decades of experience designing and building durable drilling solutions. Every S82 unit is assembled and tested in‑house to ensure reliability in the toughest conditions. Unlike generic models, the S82 is purpose‑built for confined mining—where every centimeter and minute counts. It proves that specialized engineering can turn tight spaces into productive workplaces.

The S82’s performance stems from several refined features. Its barrel uses hardened steel with a patented anti‑jamming flute, reducing debris clogs during deep hole drilling. The ergonomic front handle adjusts to multiple angles, giving operators control over awkward inclines. Additionally, the integrated silencer cuts noise levels below 85 dB, protecting hearing in enclosed areas. For maintenance, the sealed percussion mechanism requires only weekly grease lubrication, minimizing downtime.

Mines now deploy the S82 not only for crosscuts but also for bolt‑hole drilling and secondary blasting holes in cramped stopes. Its versatility extends to varying rock hardness—from shale to medium‑density granite—without loss of impact force. The tool’s quick‑connect couplings allow it to work with existing mine air lines, eliminating the need for retrofitting.

Field data from several underground sites show that the S82 maintains peak performance for over 1,500 hours before major servicing. This endurance translates into fewer equipment swaps during critical development phases. As narrow‑vein mining becomes more common, the industry’s shift toward compact, high‑yield drills like the S82 is accelerating. Our factory continues to refine the design based on direct miner feedback, ensuring it remains the go‑to choice for confined spaces.

In essence, the S82 transforms logistical challenges into operational advantages. It enables crews to advance headings on schedule, supports safer working conditions, and cuts direct drilling costs. For any mine struggling with tight underground passages, this drill offers a proven path forward.
