Product Desciption
Introduction of Friction bolt
Friction bolt is a new bolt of full length anchoring and active reinforcing surrounding rock.
And it is a high strength steel pipe with longitudinal slit.
Application:
Mining Friction bolt mainly use in supporting mine laneway and mountain tunnel, secondary support of mine tunnel.
Parameter of Friction bolt
We Better Onward as factory could customize friction bolt according to your detailed requirements.
We also have MF-40,MF-43,MF-46,MF-49 series.
Images of Friction Bolt
Install the friction bolt in a bore which smaller than the pipe diameter.
At this time, three forces will be applied to the surrounding rock.

Images of Friction Bolt
Install the friction bolt in a bore which smaller than the pipe diameter.
At this time, three forces will be applied to the surrounding rock.
1. Friction bolt entire length range give radial pressure on the hole wall.
2. friction force to prevent the surrounding rock from falling.
3. Friction bolt's plate bearing force.
These three forces make the surrounding rock more stable.
Technical characteristics
1. Material adopt high-strength alloy strip steel;
2. the installation is the simplest;
3. Don't need resin cartridges
4. The friction force between the friction bolt and the rock mass is large;
5. Bear high shear resistance and tensile strength;
6. equipped with high-strength plate, evenly force;
7. The height of the tunnel is higher than the length of the bolt.
