Technical Description: Deep-Hole (400m) Tunnel Exploration Core Drilling Rig
Purpose: Advanced geotechnical investigation for deep tunnel projects (e.g., hydroelectric, rail, mining access).
Core Capability: Designed for continuous wireline or conventional core drilling to depths exceeding 400 meters.
Key Design Features:
High-Torque Power System: Heavy-duty hydraulic or electric drive system capable of handling dense, abrasive rock at significant depth.
Stable Drill Mast: Reinforced, tall mast structure with a strong feed system to manage long drill string loads.
Deep-Hole Optimization: Equipped with wireline hoists, rod break-out tools, and high-pressure mud pumps for efficient circulation and sample recovery.
Sample Integrity: Utilizes triple-tube core barrels and precise pressure control to obtain undisturbed, high-quality core samples from great depths.
Primary Value: Provides unparalleled subsurface data for risk mitigation, final tunnel alignment confirmation, and support system design in ultra-deep geological settings.
