High-Powered 400-Meter Hydraulic Core Drill for Deep Tunnel Exploration

This heavy-duty, deep-hole hydraulic core drill is a master-engineered system designed to conduct critical subsurface investigations at unprecedented depths of up to 400 meters within and around tunnel projects. It serves as a pivotal tool for ultra-deep geological mapping, resource assessment, and geotechnical hazard identification in the planning and construction of long tunnels, deep mines, underground research laboratories, and deep geological repositories.

The system's core technological advantages include:
High-Pressure Hydraulic Drive: Offers superior power density, smooth control over drilling parameters (RPM, feed pressure, fluid flow), and reliable performance in environments where electrical power may be limited or hazardous.
Advanced Wireline Coring System: Enables rapid retrieval of continuous, high-quality core samples from great depths without the need to hoist the entire drill string, dramatically increasing operational efficiency and core recovery rates.
Integrated Mud Circulation & Conditioning Unit: A high-pressure pump and sophisticated fluid management system are essential at 400-meter depths to ensure effective hole cleaning, bottom-hole cooling, and—most critically—borehole wall stabilization to prevent collapse.
Automated Rod Handling & Breakout: Features a semi or fully automated pipe handling system to manage the extensive drill string, significantly enhancing safety and reducing manual labor and connection time.
Comprehensive Data Acquisition: Equipped with sensors and a digital console to monitor and log real-time parameters (depth, pressure, torque, penetration rate, fluid pressure), providing valuable data for formation evaluation and drill performance optimization.
