Mobile Core Drilling Rig Tunnel Exploration Sampling Drilling Machine Rotary Borehole Core Drill Rig

Geological exploration hydraulic core drilling rig for tunnels and underground drifts is a specialized, heavy-duty drilling system engineered for subsurface investigation in confined underground mining and tunneling environments. Mounted on a compact track or skid base, it is designed to navigate narrow access adits, crosscuts, and tunnel headings while delivering powerful and precise core sampling capabilities.

The rig utilizes a fully hydraulic power system to drive the rotary head, feed mechanism, and auxiliary functions, providing high torque, smooth speed control, and reliable performance in demanding rock conditions. It is equipped with a robust drill mast, a wireline or conventional core barrel system, and often features an automated rod handling mechanism to enhance safety and productivity in tight underground spaces.

Applications include extracting undisturbed cylindrical rock cores from boreholes drilled ahead of or around tunnel faces and drift walls. The geological data obtained — such as rock quality designation , fracture orientation, groundwater inflow, and strength parameters — is essential for validating excavation plans, designing ground support systems, identifying fault zones, and mitigating geological hazards in underground construction and mining projects.

Key design features emphasize modularity for easy underground transport, corrosion-resistant components for wet conditions, ergonomic controls for operator safety, and dust suppression systems to maintain air quality in enclosed environments.
