Friction bolt

Friction bolt is the most basic part of roadway support in contemporary coal mines, it reinforced the surrounding rock of the roadway, make the surrounding rock support itself. The bolt is not only used in mine, but also used in engineering technology.
Application: Since 1912, it is the first time that Seleznev use the bolt to support in the underground roadway. It has been widely used in civil engineering(including mining engineering)
