Siton DL31 long-hole drill rig with boom-mounted drill unit is designed for work in underground mining drifts with cross sections of 4x4-5.6x5.6 m. Capable drilling vertical and inclined fans or single and parallel 64-89 mm longholes up to 40 m in depth. With portable wired/wireless remote control, standard hands-free rod handling system and optional remote-control system, this powerful rig machine enables continuous multi-shift operations, making it an intelligent choice for modern underground mining.

Features and benefits

1.Safety

Given the inherent risks associated with drilling operations, such as falling rocks, equipment rollover, and the safe loading and unloading of rock bolts, it is crucial to ensure the safety of operators. Siton addresses these concerns by equipping our deep-hole drilling rigs with canopy certified for FOPS (Falling Object Protective Structure) and ROPS (Roll Over Protective Structure), providing robust protection for operators. Additionally, our long hole drill rig machines are equipped with SAHR (Spring Applied Hydraulic Release) braking systems and emergency stop buttons, ensuring rapid response to any safety hazards.

2.Versatility

The retractable type of boom can meet the needs of drilling operations at various angles. The feed beam is flipped 360°, which can drill upward and downward holes. The direct positioning control method can meet the needs of hole operations at any angle of the top and side of the tunnel without dead ends.

3.Automation

DL31 production underground mining drill rig is equipped with automatic anti-jamming function and automatic anti-blank firing system, which can extend the lifetime of the drilling tools. Equipped with an automatic hands-free rod handling system and the optional carousel capacity for rod is 21+1 pcs, enabling fully automatic rod handling.

4.Flexibility

DL31 longhole underground mining drill rig adopts a central articulated structure and four-wheel drive. This design ensures exceptional passability and steering precision in narrow drifts. The fully hydraulic power steering system reduces operator workload and enables agile maneuvering even under harsh underground conditions.

5. Ease of Maintenance

Compact and reasonable structure allows all daily maintenance to be performed from the ground, saving time and labor. The layout of key components is clear, which facilitates quick positioning and troubleshooting. This Long-hole Drilling Rig is equipped with a standard automatic centralized lubrication system, simplifying maintenance procedures, reducing labor cost, and minimizing maintenance risks.
