Because of its performance, GRP dowel has a very wide range of applications and a very wide market prospect. After more than 40 years of development, my country's glass fiber reinforced plastic industry has also achieved successful applications in various fields of the national economy, and has played a role in economic construction. played an important role.
Advantages of GRP dowel:
1. GRP dowel is lightweight and high-strength: the relative quality of FRP is only 1.5-2.0, but the strength can be close to the level of steel. The support strength of GRP dowel is close to that of steel bolts, but its weight is only the same specification of steel bolts about 1/5 of .
2. GRP dowel is easy to cut and does not produce sparks. FRP is a non-metallic material, which is easy to cut and does not produce sparks, and is especially suitable for "mechanized mining" operations. It not only ensures the safety of underground operations, but also solves the role of mine anchoring and support, which can greatly improve the efficiency of coal mining, greatly reduce the damage of the cutting teeth of the coal cutter, and reduce the production cost. In addition, the GRP dowel is transported into the warehouse together with the coal after being cut, which avoids the damage to the equipment caused by the scrap steel bolt.
At present, the quality of GRP dowel produced in China has been greatly improved compared with the previous ones, which can meet the support needs of most mining tunnels. Although the application scope of GRP dowel has been expanded a lot, the current application of this bolt in coal mines is still limited to the support of mining roadways with short service life.
