1. Good cutting ability:
The resin anchor rod is a composite material composed of unsaturated polyester resin as the matrix material and glass fiber as the reinforcement material, with high tensile strength but low shear resistance. This allows the shearer to directly cut the resin anchor rod, avoiding the spark problem generated by the shearer drum during direct cutting, thereby reducing the risk of coal dust and gas explosions.
2. Lightweight:
The density of resin anchor rods is generally around 2.0g/cm ³, which is only 1/4 of that of metal anchor rods, greatly reducing the difficulty of transportation.
1, Application site:
Resin anchor rods are commonly used in coal mine engineering, with the main focus being on the following aspects:
1. Tunnel support:
In coal mine tunnels, resin anchor rods can effectively increase the support force of the tunnel, enhance the stability and safety of the tunnel.
2. Rock layer control:
To control rock layer instability caused by geological reasons, resin anchor rods can be used to reinforce the rock mass and enhance its stability.
Top plate support: Resin anchor rods can also be used as part of the top plate support to ensure the safety and stability of the top plate.
2, Installation and operation:
The installation and operation of mining resin anchor rods require following certain regulations and standards, including drilling anchor holes, installing resin anchor rods, stirring resin anchor agents, and other steps. During the installation process, it is necessary to ensure that the position, angle, and depth of the anchor rod eye meet the requirements,and to check the model and expiration date of the resin anchoring agent to ensure installation quality.
In summary, as a new type of anchor material, mining resin anchor rods have broad application prospects and significant technological advantages in mining engineering. Safe production and stable operation of mines can be ensured through reasonable selection and use.
