An underground large-scale drilling rig is a heavy-duty mechanical system designed for excavation, tunneling, or resource extraction in subsurface environments.
Equipped with high-powered hydraulic or electric drive systems, it integrates high quality cutting tools, such as rotary drill heads or tunnel boring machines , capable of penetrating hard rock, soil, or mixed geological formations.
These rigs often feature modular designs for adaptability in confined spaces, real-time monitoring sensors for precision alignment, and automated control systems to optimize efficiency and safety.
The auger drill rod simultaneously transmits rotational energy downward while conveying excavated material upward through its helical flights. This mechanized process enables precise vertical/horizontal boring for applications including foundation piling, tunnel construction, utility installation, and mineral exploration. Modern rigs incorporate computerized monitoring systems to optimize rotational speed, feed pressure, and alignment control, ensuring operational efficiency while minimizing ground disturbance in urban or environmentally sensitive areas.
Technical Precision
Integrates real-time monitoring systems for accurate depth, angle, and force control.
Compatible with modern tunneling methods (e.g., NATM, TBM).
