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.
