Hfdd-2 Wheel Mining Drill Rig for Flexible Mobility in Underground Gold and Metal Mines

Product Description

Product Description                     

Features

• This compact and flexible single-boom face drilling rig is engineered for high-efficiency underground mining and drifting applications. Upgraded with an extended boom based on a proven platform, it adapts seamlessly to drift cross-sections from 2.8×2.8 m to 6×6 m. Its patented telescopic boom and compact frame make it an ideal solution for narrow drifts in small-to-medium mines, delivering reliable performance in complex underground environments.
• Powered by a high-pressure, low-flow hydraulic system, the rig comes standard with an 18 kW rock drifter (with 20 kW/22 kW high-performance options). It achieves exceptional penetration rates even in F17 hard rock, while its unique dual-damping design minimizes vibration, extends component lifespan, and lowers operational costs.
• The 360° rotating parallel telescopic boom enables precise wall hole and cut hole drilling with a single positioning, significantly reducing cycle times and improving blasting results. An optional dual-layer telescopic feed beam supports both single-layer bolt hole drilling and dual-layer face drilling, eliminating the need for frequent equipment repositioning and boosting efficiency in short-hole blasting scenarios.
• Safety is prioritized with a FOPS (Falling Object Protective Structure) and ROPS (Roll Over Protective Structure) certified canopy, providing robust protection for operators against falling debris and rollover incidents. The hydraulic system also integrates an automatic anti-jamming and retraction function, reducing drill rod sticking and unplanned downtime to enhance overall operational reliability.
   

Key Features & Benefits

1. Telescopic Parallel Boom
   The long telescopic boom offers wide coverage, 360° rotation, and automatic parallel adjustment. It enables accurate wall hole and cut hole drilling with one positioning, improving blasting performance and overall productivity.
2. High-Power Rock Drilling
   Equipped with a high-pressure hydraulic system and a powerful rock drifter, it delivers fast penetration rates in hard rock. The dual-damping design reduces vibration, extending component life and lowering operating costs.
3. Versatile Telescopic Feed
   The optional dual-layer telescopic feed beam supports both bolt hole and face drilling operations, reducing equipment repositioning and enhancing efficiency in multi-task underground scenarios.
4. Intelligent Hydraulic System
   Powered by an internationally renowned plunger pump, the hydraulic system features anti-jamming and automatic retraction functions, minimizing tool wear and unplanned downtime for greater reliability.
5. FOPS & ROPS Certified Safety
   The certified canopy provides reliable protection against falling objects and rollovers, ensuring maximum operator safety in high-risk underground conditions
