Specifications
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)
Specification: 18*2m, 16*6m (customize according to customer requirement)
Material: 16Mn, 20Mnsi
Characteristic:
1. High strength alloy strip steel is used for raw materials;
2. The simplest installation;
3. No anchoring agent;
4. Large friction force between the bolt and rock mass;
5. High shear and tensile strength;
6. Equipped with high-strength pallet, the pallet is evenly distributed;
7. The roadway height is greater than the bolt length.
