Hollow Anchor Rods for Mining
Anchor bolt
Anchor bolt means a rod that transfers the structures or geotechnical load to a stable rock formations,
it consistsof rod, drill bit,coupling, plate, grouting stopper and nut. It has been widely used in tunnling,
mining,slope stabilization, tunneldiseasestreatment and roof supporting of undergroundworks. It is for
loose ground(clay, sand friable etc.) Hollow anchor rod is made of seamless tube with high strength.
Features of Hollow Grouting Anchor Bolt:
• 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

Technology Process
1. Connect the alloy drill and anchor rod one end, on the other
end, connect the drill sleeve and shank adapter ,then connect the
drilling rig or hand-held drill. Then start drilling, fill the
cooling water while drilling.( If you want to lengthen the anchor
rod, can connect the coupling, and then drilling)
2. Take down the drill, put the stop-grouting plug into the rod, and insert it to the hole, then ready to grout. Special circumstances like surrounding rock grouting tension is over or surrounding rock is too broken, can use anchor agent to seal the hole.
3. Connect quick grouting coupling and anchor rod end, connect other end of grouting machine.
4. Start grouting, when grouting full and reach design value then power off . Grouting pressure according to the design parameters and grouting machine performance determine ,Cement/sand reference values is 1:0 ~ 1:1, water/cement reference value is 0.45:1 ~ 0.5:1.
5. Install anchor plate and nuts, and tighten nuts.
