Friction stabilizer

Friction stabilizer (slit rock bolt)has many advantages such as initiative reniforce,surrounding rock with full bolt,reinforce anchor immediately and etc. The bolt is installed in a hole which has smaller diameter than it. It can immediately process radial pressure to the hole to prevent rock falling. When surrounding rock is shaked by explosion, anchor capacity increasesed higher and supporting effect is perfect.

Friction Stabilizers are mainly used for rock reinforcement in underground Mining. The shaft of the Friction Stabilizer consists of a metal strip which is folded to form a slotted tube. The bolt is installed into a borehole by applying impact energy. The borehole features a slightly smaller diameter than the outer diameter of the bolt tube. The principle of this anchor system is based on the bond between the borehole and the tubular bolt shaft, caused by applying a force onto the borehole wall, which generates a frictional resistance in axial direction. The main field of application of this rock bolt is underground metal ore or hard rock Mining. Recently, a self-drilling friction bolt system, the POWER-SET Self-Drilling Friction Bolt, has been developed in addition to conventional Friction Stabilizers.

Fields of Application:

Systematic reinforcement of underground excavations

Rock bolting in hard rock mining

Additional reinforcement and utility bolting

Main Advantages:

Easy and fast installation procedure

Both hand-held and fully automated installation are possible

Immediate load-bearing capacity after installation

Low sensitivity to rock mass displacements
