pneumatic rock bolting rig for underground projects

Pneumatic Rock Bolting Rig

The pneumatic rock bolting rig is a highly efficient drilling device specifically designed for underground roadways and construction in hard rock formations. Powered by compressed air, the pneumatic rock bolting rig is suitable for rock roadways with a hardness coefficient of f≤10, and is capable of drilling roof bolt holes, cable bolt holes, as well as mixing and installing resin cartridge bolts and cables. It can complete the installation and tightening of bolt nuts in one step, achieving initial pre-tightening of the anchor bolts without the need for additional tools.

Main Features of the Pneumatic Rock Bolting Rig

• Compact structure and lightweight design, easy to transport and operate, with simple and effortless maintenance;
• Equipped with a gear-type pneumatic motor featuring high torque and high speed, ensuring stable operation and strong reliability;
• The motor has a vibration function, which effectively improves rock breaking efficiency and provides a faster drilling speed than ordinary rigs;
• Excellent intrinsic safety and explosion-proof performance, high wear resistance, enlarged cylinder diameter, and enhanced thrust force;
• Dual exhaust design allows for faster leg retraction, significantly improving operation rhythm and overall efficiency.

Application Fields

The pneumatic rock bolting rig is widely used in coal mine roadways, tunnels, and rock slope projects for rock bolting support and reinforcement. It is especially suitable for underground environments with high explosion-proof requirements and limited working space, effectively improving the efficiency and safety of rock bolt installation and construction.
