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.
Installation Manual
- Drill a hole according to design specifications
- Clean rock powder from the hole with compressed air
- Mount plate through rod, then push rod into hole using a shock drill machine
Technical Advantages
- High-strength plate with bearing capacity exceeding the rod's capacity
- Block ring with bearing capacity exceeding the rod's capacity
