Product Description
Friction Split Sets Anchor Bolt for Underground Mining Support
Friction stabilized anchor is a new type of anchor with full-length anchorage and active reinforcement of surrounding rock. It consists of anchor rods and trays. The anchor rod is made of high-strength steel pipe with longitudinal slits. When installed in a borehole slightly smaller than the pipe diameter, it immediately exerts radial pressure on the entire borehole length and prevents surrounding rock from slipping. Together with the supporting force of the pallet, it puts the surrounding rock in a three-way force state and achieves effective rock stabilization.
