Introduction of KD55 Tunnel Core Drilling Rig

Fully hydraulic core drilling rigs constitute the core equipment for underground mining exploration. Their primary function involves conducting advance drilling ahead of the ore body to obtain deep core samples, enabling precise analysis of geological structures, ore grades, and rock stability. These provide critical data for mine planning and development, offering early warning of geological hazards such as faults and aquifers. This safeguards mining operations for safety and efficiency, thereby optimising extraction plans and reducing operational risks and costs.
