Tunnel Jumbo Drilling Rig Construction
In large-scale tunneling projects, heavy-duty tunnel jumbos are deployed to execute high-efficiency drilling operations. These drilling rig, equipped with multiple robotic booms and high-torque drilling systems, are designed to bore blast holes, rock anchor holes, or ventilation channels across extensive tunnel sections.
For mega-tunnels, synchronized jumbo fleets work in tandem to accelerate progress, minimizing downtime and adapting dynamically to complex rock formations. Post-drilling, explosives or reinforcement materials are strategically installed to enable controlled excavation and long-term structural stability.
Enhanced Safety
Reinforces ground stability by installing support structures (anchors/bolts) to prevent tunnel collapse and rockfalls.
Minimizes risks for workers during excavation in unstable geological conditions.
High Efficiency
Enables rapid drilling and anchoring operations, accelerating project timelines.
Reduces manual labor through automated or semi-automated systems.
