SANROCK SRJ18 Underground Jumbo Drilling Rig Scope of application One-boom face drilling rig for medium sized underground drifts,
with coverage area 7-35m².
Underground Tunnel Single Face Boom Jumbo Drilling Rig Machine
Underground Tunnel Drilling Rig Machine is a heavy-duty, mechanized excavator engineered for constructing extensive subterranean passageways with high efficiency and precision. Designed to tackle challenging geological conditions—such as hard rock, soft soil, or mixed ground—this equipment integrates cutting, excavation, debris removal, and structural support installation into a seamless, automated process.
Key features include a massive rotating cutterhead equipped with durable disc cutters or picks for effective fragmentation of ground material. A continuous conveyor system efficiently transports muck away from the working face, while hydraulic or electric propulsion provides the necessary thrust for forward movement. Advanced guidance and monitoring systems ensure alignment accuracy, minimizing deviation and enhancing safety throughout the tunneling operation.
These machines are essential for developing large-scale infrastructure, including metro networks, railway and road tunnels, water supply and sewage systems, and utility corridors. Their capability to operate in confined, variable environments with reduced human intervention makes them a cornerstone of modern civil engineering.
By combining robust construction, automation, and adaptability, the Underground Tunnel Large Boring Machine significantly accelerates project timelines, lowers operational risks, and supports sustainable urban and industrial development.
