Brief Introduction of GFRP ROCKBOLT FOR COAL MINE APPLICATION
Fiber reinforcement polymer, also called Fiber Reinforce Plastic, is a kind composite material whichmatrix is resin(epoxy, vinylester and unsaturated polyester), fiber as reinforcement (glass, basalt andcarbon fiber), after composite processing.
Main Application of GFRP ROCKBOLT
The GFRP bolts have also been used in many pilot tunnels,caverns, water-adits, slope stabilizations andquarries. They have been used successfully in many applications like:
- TunnelsandCulverts
- MineRoadways
- Civil Engineering
- Piers andSeawalls
- Military Engineering
- Roads andBridges
- AirportRunways
- Mountain Slope Supports
- Form Work and Concrete Reinforcement
Main Advantage of GFRP ROCKBOLT FOR COAL MINE APPLICATION
High CorrosionResistance The base materialsused by the bolt are durable materials, and they are molded through thecomposite process. The life span is up to 100 years. They can be used aspermanent support materials;
High Tensile Strength: Theload is approximately double that of a steel bar with the same diameter
Low Weight: Theweight is only 1/4 that of a steel bar with the same diameter. Therefore, thelabor intensity is greatly reduced, and the transportation cost is reduced atthe same time;
Anti static It has noelectrical conductivity, and no sparks will be produced when being cut. It isparticularly suitable for high gas zones;
Non-flammable It is non-flammable and has high thermalisolation;
Cuttability It avoids damages to cutter heads,and does not delay excavation
Save cost Use this material as reinforcing bars for road and bridge, could reduce Secondary repair cost.
