Product Description

42mm Split Set Bolt Friction For Gold Mine Use

High Quality Friction Bolt for Gold Mine Use

Pipe-slit anchor rods, also known as seam-tube anchor rods and friction anchor rods, are active reinforcements for surrounding rock. They feature full anchoring and immediate bearing capacity. When installed in a borehole slightly smaller than the pipe diameter, they immediately exert radial pressure on the hole wall over the entire length to prevent surrounding rock from sliding. Under blasting vibration and rock displacement conditions, the anchoring force increases significantly for more effective support.
