Mining Threaded Steel Rock Bolt

Product details

The usage environment of Mining Threaded Steel Rock Bolt is mainly affected by various factors such as geological conditions, cave wall conditions, temperature, humidity, and acidity and alkalinity.

 

Firstly, Mining Threaded Steel Rock Bolt are mainly suitable for engineering projects with good geological conditions. The effect will be better when used in areas with familiar geological conditions. If the geological conditions are too poor, there may be problems such as poor support effectiveness and frequent safety issues. Therefore, it is necessary to accurately measure the predetermined position and explore the soil and rock layers to determine the length and diameter of the resin anchor rod.

 

Secondly, the bearing capacity of Mining Threaded Steel Rock Bolt is limited, making it unable to provide effective support for large-scale collapse of tunnel walls. Therefore, when installing Mining Threaded Steel Rock Bolt, it is necessary to strictly inspect and evaluate the condition of the tunnel or chamber walls, and if necessary, repair and reinforce them.

 

In addition, factors such as temperature, humidity, and pH in the usage environment can also affect the anchoring performance of Mining Threaded Steel Rock Bolt. Mining Threaded Steel Rock Bolt that are exposed to harsh environments for a long time may experience aging, detachment, and other phenomena, which can reduce the fixing effect. Therefore, it is necessary to regularly inspect and maintain Mining Threaded Steel Rock Bolt to ensure that they are in good working condition.

 

Overall, the use environment of Mining Threaded Steel Rock Bolt needs to meet certain geological conditions and cave wall conditions, while also paying attention to the impact of environmental factors on their performance. In practical engineering, appropriate resin anchor rod types and installation methods should be selected based on specific situations to ensure that they can achieve the best support effect.

 

The manufacturing process of Mining Threaded Steel Rock Bolt mainly includes the following steps:

• Raw material preparation: Ensure that the raw materials meet the technical standard requirements.


• Cutting: According to the drawing requirements, adjust the distance between the cutting edge of the steel bar cutting machine and the cutting positioning stopper to meet the size requirements.


• Round rolling: Use a round rolling machine to press the thread at one end of the threaded steel into the rod body, achieving the diameter and length of the rolling thread.


• Straightening: Place the rod body with non straightness exceeding the standard on the straightening platform for straightening.


• Rolling: Use a rolling machine to round the part of the rod body into standard threads.


• Bundling: Bundle according to regulations, such as Ф 20 x 2400mm anchor rods are bundled in bundles of five, while other anchor rods are bundled in bundles of ten. The two ends are securely tied with iron wire.


• Storage: After passing the inspection and hanging the certificate of conformity, it is stored in the warehouse.
