Product Description

25mm-130mm Diameter Self Drilling Anchor Bolt Hollow Anchor Bar Anchor Rods for Mining
The self-drilling hollow bar anchor system consists of a hollow threaded bar with an attached drill bit that can perform drilling, anchoring and grouting in a single operation.
Key Features
  • Allows air and water to freely pass through the bar during drilling to remove debris
  • Enables grout injection immediately after drilling completion
  • Grout fills the hollow bar and completely covers the entire bolt
  • Couplings can join hollow bars to extend bolt length
  • Nuts and plates provide required tension
Applications
The most common system for rock mass stabilization, especially in:
  • Tunneling
  • Underground mining
  • Ground engineering
  • Supporting engineering in loose and broken rock strata
  • Soil nailing, lock bolting, and micro-piling
