Application characteristics

(1)Split set bolt has good supporting effect.

Bolt support conforms to modern rock mechanics and surrounding rock control theory in terms of support principles, and belongs to active support. After the bolt is installed, the stability of the surrounding rock can be mobilized and utilized, and the bearing capacity of the surrounding rock can be fully utilized, and controls the deformation of the surrounding rock of the roadway effectively.so split set bolt can protect the stability of the surrounding rock of the roadway and improve the maintenance of the roadway.

(2)Split set bolt has simple installation and labor saving.

It uses fewer supporting materials and lighter weight than other bolts. When tunneling, the transportation volume of supporting materials is reduced, and the labor intensity is greatly reduced, which is conducive to improving the efficiency of tunneling
