Product Description
Mine friction anchor bolt mining rock bolts is mainly used in underground engineering ,like weak surrounding rock, fault fracture zone, highland stress large deformation and other complex geology. especially in serious hole collapse and deep fault rock situation, ordinary anchor rod is incapable of action. LHZ anchor bolt set drilling, grouting, lengthen and anchoring multifunction all in one, in all kinds of bad surrounding rock engineering applications achieved ideal support effect.

Application
Tunnelling Ground engineering
• Radial bolting • Slope stabilization
• Forepoling • Micro injection pile
• Face stabilization • Temporary support anchor
• Portal preparation • Soil nailing
Features and Advantages
• Fits standard Boomer, ROC and Mustang rigs.
• Particularly suitable for difficult ground conditions.
• A high rate of installation since drilling, placing and grouting can be performed in one single operation.
• Self drilling system eliminates the requirement for a cased borehole.
• Installation with simultaneous drilling and grouting possible.
• Easy installation in all directions, also upwards.
• Suitable for working in limited space, height and in areas of difficult access.
• Simple post grouting system.• Hot-dipped galvanizing for corrosion protection
