Hydraulic Core Drilling Rig Portable Underground Drill Rig Core Sample Drilling Rig Manufacturer

Performance Description: Portable Underground Tunnel Core Drilling Rig
This rig is engineered for maximum flexibility and efficiency in the confined, dynamic environment of tunnel construction. It prioritizes compactness, rapid deployment, and precision without compromising core sample quality.
1. Ultra-Compact & Modular Design:
Designed with a minimal footprint, often using a lightweight, rigid frame or a compact track/skid base. Key components (power pack, control unit, drill head) are modular, allowing for manual transport through narrow tunnel passages and assembly in restricted spaces near the tunnel face or sidewalls.
2. Lightweight yet Powerful Drilling:
Utilizes a high-torque, low-speed hydraulic or electric drill head, powered by a compact diesel or electric power pack. Engineered to deliver sufficient thrust and rotation for coring in hard rock (using diamond bits) while maintaining a total weight that allows for positioning by small equipment or crews.
3. Quick Setup & Alignment:
Features simplified anchoring systems (e.g., mechanical jacks or rock anchor points) and laser/integral bubble guides for fast and accurate alignment of the drill hole angle (for probe, horizontal, or inclined drilling).
4. Core Drilling Excellence in Confined Space:
Capable of extracting standard-size (e.g., NQ, HQ) or smaller-diameter, high-quality rock cores. The system ensures precise core orientation and recovery, providing critical data on lithology, fracturing, and RQD.
5. Manually or Semi-Automated Rod Handling:
Optimized for single-rod or short-series rod handling by 1-2 operators, often with assistive clamps and breakout tools to maximize safety and efficiency with minimal crew.
6. Integrated Dust & Water Management:
Equipped with a closed-loop cooling system and efficient dust suppression, which is crucial for maintaining air quality and visibility in the enclosed tunnel environment.
