Working Principle of Split Set Bolt

Split Set Bolt:

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 of split set bolt:

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.
