SANROCK Jumbo Rock Drilling Rig Underground Drilling Equipment Tunnel Mining Drilling Machinery

SANROCK Jumbo Rock Drilling Rig Underground Drilling Equipment Tunnel Mining Drilling Machinery

Jumbo Underground Tunnel Boring Machine SRJ18 is a massive, high-performance engineering system designed for excavating tunnels of significant diameter through various subsurface conditions, including rock, soil, and mixed geology.

Engineered for robustness and precision, the SRJ18 features a rotating cutterhead equipped with disc cutters or other specialized tools to break down the ground mechanically. Muck removal is efficiently handled via a conveyor system, while segments of the tunnel lining are simultaneously erected to ensure structural integrity and safety.guidance and control systems enable real-time monitoring and adjustments, optimizing tunneling accuracy and minimizing surface disruption.

These machines are critical to the construction of major infrastructure projects such as metro systems, railways, highways, water diversion tunnels, and utility passages. Their ability to operate in challenging ground conditions—with high levels of automation, reduced labor requirements, and enhanced safety protocols—makes them indispensable for modern large-scale subterranean development.
Underground Tunnel Boring Machines represent the forefront of tunnel construction technology, driving progress in urban and intercity connectivity.
