Tunnel core drilling rigs constitute the core equipment for underground exploration in mines, their principal advantage lying in enabling precise, efficient in-situ detection. Without requiring surface access points, they can drill directly within tunnels in any direction—particularly along the strike and dip of ore bodies—significantly reducing time and costs. The cores obtained provide the most direct evidence for assessing ore body boundaries, grade variations, geological structures, and potential hazards (such as faults and aquifers), offering unparalleled data reliability.
Their primary applications include:
1. Production Exploration: Tracing and defining ore bodies near or deep within mining levels to guide working design and ore allocation, directly enhancing resource recovery rates and mining efficiency.
2. Engineering and safety exploration: Investigating geological conditions and groundwater hydrology ahead of roadways to provide advance warnings for shaft and tunnel excavation, ensuring construction safety.
3. Geological surveys and sampling: Used for deep ore body studies, resource reserve upgrade verification, and various geotechnical testing samples, serving as a critical tool for geological management throughout a mine's entire lifecycle.
