Jumbo Underground Tunnel Drilling Rig
Single Face Boom Jumbo drilling rig machine is a powerful, highly mechanized excavation system designed for constructing extensive subterranean tunnels with exceptional precision and efficiency. It integrates multiple functions—including cutting, material removal, and structural support installation—into a continuous, automated process, making it indispensable for modern large-scale infrastructure projects.
Equipped with a massive rotating cutterhead fortified with robust disc cutters or picks, the SRJ18 effectively fractures and removes rock, soil, or mixed geology. An integrated conveyor system transports excavated material (muck) away from the cutting face, while hydraulic or electric propulsion mechanisms drive the machine forward with controlled force. Sophisticated guidance systems ensure accurate alignment, minimizing deviations and enhancing operational safety.
These machines are widely used in the construction of metro systems, railway and road tunnels, hydraulic and utility tunnels, and other major underground passages. Their ability to operate in challenging ground conditions—combined with high automation, reduced labor dependency, and minimized surface disruption—makes them a preferred choice for sustainable urban and intercity development.
SANROCK SRJ18 Underground Jumbo Drilling Rig Scope of application One-boom face drilling rig for medium sized underground drifts,
with coverage area 7-35m².
