A tunnel or exploratory drift core drill rig is a specialized drilling system designed for geological sampling and subsurface investigation in tunnel construction and mining projects. It is used to extract cylindrical rock cores from boreholes drilled along or ahead of a tunnel path, providing critical data on rock quality, geological structures, groundwater conditions, and material properties.
This rig typically features a compact, modular design for easy transport and operation within confined tunnel environments. It is equipped with a robust drilling mechanism—often hydraulic or electric-powered—capable of performing diamond core drilling in various rock formations. The system includes a drill head, rod handling system, core barrel, and precise feed control to ensure high core recovery and minimal disturbance to the samples.
Common applications include pre-excavation ground verification, fault zone detection, rock strength testing, and confirming geological models during tunnel driving. By enabling informed decision-making, core drill rigs help mitigate geological risks, optimize support design, and enhance safety and efficiency in underground engineering.
