Mining Friction Stabilizer Bolt
Mining Friction Stabilizer Bolt is a type of anchor rods that are fully anchored, actively reinforce the surrounding rock, and immediately bear the load. It can immediately impose full range radial pressure on the wall of the hole to prevent rock fall.In case of blasting vibration displacement of surround rock,anchoring increases significantly,and supporting effect is ideal.
Mining Friction Stabilizer Bolt Technical advantage
High-strength plate beraing capacity,the rod body than retaining ring pull off the bearing force than pole.
