DESCRIPTION: Resin rock bolts are the most fundamental component of roadway support in modern coal mines; they strengthen the surrounding rock, allowing it to sustain the roadway itself.
SUMMARY
Spherization results in the creation of a type of bolt known as the non-longitudinal ribbed steel resin anchor bolt. The thread segment exhibits strong bending and shearing properties, with its strength surpassing that of the rod body. This new kind of anchor bolt provides the roadway with extremely strong support.
Classification: Resin bolts with left and right hands.
