What is the threaded steel anchor rod used in mining

Sep 30, 2022 Leave a message

The performance of mining threaded steel anchor rods has reached the international advanced level, with a reasonable structure
The full thread length of the anchor rod has equal strength, which increases the bearing capacity by 40% compared to the same specification anchor rod;
Expanding the range of anchor rod use, it can achieve end anchor, extended anchor, and full anchor; Easy to operate,
It has the advantages of low price and is widely used for supporting various types of tunnels in coal mines, railways, hydropower and other engineering projects.
The threaded steel anchor rod used in mining is used for supporting the surrounding rock of mine tunnels and underground engineering, which can ensure the stability of the surrounding rock of mine tunnels and underground engineering. Its structural features: the entire length of the rod body has continuous threads rolled, with equal strength throughout the entire length; The fastening end is equipped with a pre-stressed gasket and a ball nut. It is superior to anchor rods processed with round steel, with the following advantages: 1. The anchoring and fastening ends do not require machining; 2. Full length equal strength, high material utilization rate; 3. High anchoring force; 4. Equipped with pre-stressed gaskets, easy to control installation quality; 5. Fast installation speed, etc. It is a new type of anchor rod with material saving, labor saving, and equal strength, and has broad prospects for promotion and application.
