42mm Split Set Bolt Friction For Gold Mine Use

42mm Split Set High Quality Friction Bolt for Gold Mine Use

Production introduction

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

(1)drill a hole According to the requirement of design
(2)Clean rock powder in the hole with compress air
(3)Mounting plate through rod,then push rod into hole with shock drill machine

Technical advantages
High-strength plate’s bearing capacity higher than rod’s, block ring’s bearing capacity higher than rod’s
