Hollow bolts The hollow bolts used in mines compare with traditional metal composite anchor cables and have the advantage that they cannot be replaced. In terms of characteristics, the rod body is easy to be cut by fiber laser, which has the function of maintenance for the cutter head of the shearer; explosion-proof and anti-static, fiber laser cutting is not easy to cause flames, which is extremely beneficial to the safe construction of coal road construction sites and is very suitable for high coalbed methane concentration Value area; high toughness and corrosion resistance, light and easy to operate, the net weight is only 1/4 of the same type and specification steel anchor cable.

　　What are the advantages of Xinben’s recommended mine hollow bolt:

　　Hollow grouting bolts can be designed for convenient use in narrow indoor spaces such as tunnel construction and coal mines, making building construction easier, reducing labor productivity, and lowering the price compared to metal composite anchor cables, which can reduce anchor support Cost of 10%.

　　Hollow bolt manufacturer mine hollow bolt is a kind of anchor rope used as anchor rod support in coal mines. This kind of anchor rope has the same strength and length can be obtained as required. The steel anchor has good anchoring characteristics, simple and reliable, and tensile strength The advantages of high height and building construction promote its application to bolt support in coal mines, and it can also be used as bolt support in other construction projects.

　　The operation steps of Xinben's hollow anchor rod for mineral processing are as follows:

　　1. To make the anchor cable hole, the eye depth should be 80-100mm shorter than the anchor cable body.

　　2. Remove the rock dust in the anchor cable hole clean and tidy.

　　3. The quality of the drug coil should be checked before loading the drug coil, and the drug coil that is cracked and invalid cannot be used.

　　4. Put the epoxy resin adhesive roll into the macula of the eye fundus, and use the anchor cable against the roll to start mixing. After mixing, remove the common tools for mixing. After 4-6 minutes, remove the mixing tee joint, For pallets wholesale, use a special wrench to tighten the screw cap after 40 minutes.

　　Anchor cables are the most basic part of the bolt support for coal tunnels in coal mines. In addition to the hollow bolts used in mines, they are used for slope protection, tunnel construction, and dam foundations in construction engineering design. Engineering reinforcement.
