Coal Bolt

A high-strength method for active reinforcement of roadway support systems and surrounding rocks, with the threaded ends of anchor bolts treated by special processes, featuring excellent bending and shear resistance. The product is mainly applied in the support of high ground pressure mines, roadways, railways, hydropower and other projects.
  • Low support cost, improved utilization rate of roadway sections, and enhanced mining efficiency

  • Actively reinforce the surrounding rock to maintain its integrity and stability to the greatest extent and improve the support conditions
