Underground Drill Rig for Hard Rock Mining Development and Narrow Veins Drifting

Product Description

Product Description                     
Features
This all-new compact single-boom face drilling rig is purpose-built for narrow-vein underground mines, adapting to drift cross-sections from 2.3×2.3 m to 5.5×4.5 m. It is ideal for rapid blast hole drilling in underground mining, hydropower diversion tunnels, and similar applications.

Equipped with a dual-power system, the rig features a full-hydraulic operating mechanism for fast, low-energy rock drilling, paired with a diesel-powered travel system for agile movement and quick deployment. Intelligent functions like automatic anti-jamming and automatic rod retraction after drilling reduce operator workload and boost efficiency. Its compact frame and low center of gravity ensure exceptional stability, enhancing safety and performance in challenging underground environments.

Key Features & Benefits

• Dual-Power Efficiency
  Diesel power for travel and hydraulic drive for drilling deliver precise power distribution, combining mobility with high-speed rock penetration.
• Smart Drilling Protection
  Automatic anti-jamming and rod retraction minimize tool wear and unplanned downtime, improving equipment reliability.
• Compact & Stable Design
  A low center of gravity and compact structure ensure stability in narrow drifts, maintaining efficiency in complex terrain.
• Versatile Application
  Suitable for blast hole drilling in underground mining, hydropower tunnels, and more, adapting to diverse construction scenarios.
