ANTO mining friction bolt has very good quality. The surface of the anchor rod is flat without serious corrosion. The weld has no cracks, pores and slag inclusions. Welding is not allowed to burn through the pipe wall. Good quality can make sure the mining safety.

Product Description

Split set bolt, also called split set stabilizer, is an indispensable advanced material for underground mining support. Split set bolt is a very specific support product, and it is an advanced material used for the support of the roof of the underground copper or gold mining and other projects.

Working Principle

Split set bolt is a new type of anchor rod for full-length anchoring, which main part is a high-strength steel pipe with longitudinal slits. When installed in a borehole slightly smaller than the pipe diameter, The radial pressure is applied to the hole wall and the friction to prevent the sliding of the surrounding rock within the full length, plus the supporting force of the mining plate, So that the surrounding rock is subjected to forces in three directions to ensure the stability and safety of the surrounding rock. When the surrounding rock is significantly displaced, the anchor rod does not lose its supporting resistance, and it has better characteristics than the expansion shell rock bolt.

Product Features

1. The raw material is made of high-strength alloy steel strip.

2. The installation is the simple.

3. No anchoring agent is required.

4. The friction strength between the bolt and the rock is large.

5. It has high shear and tensile strength.

6. Equipped with a high-strength plate.

Advantages of Split set bolt

1.Split set bolt has simple operation and convenient use. It has anchorage in the underground anchor and shotcrete support.

2.It has strong strength, high tensile strength and strong expansion force, which makes the whole roof become one body.
