Cable Bolts

Overview

Normet offers a versatile range of cable bolting systems designed to provide robust ground support for both static and dynamic applications in underground mining and tunneling environments. These systems are engineered with high-strength, stress-relieved, low-relaxation 7-wire steel strand cables, available in various configurations to meet diverse operational demands.

Plain Strand:Plain Strand is suited to typical long-anchor support applications.
Bulbed Strand:Offers increased pull-out resistance, with options for up to 5.7 bulbs per meter for enhanced anchorage.
Spiral Indented Strands:Features a ribbed profile rolled over the full length, improving anchorage stiffness and pullout resistance by up to 75% compared to plain strands.
Yielding Cables: Features swaged collars and debonding sleeves, these cables are designed to tolerate large deformations in the rock mass while maintaining tensile capacity without failure.

Normet specialises in tailored configurations to accommodate customer-specific requirements, ensuring optimal application effectiveness and operational flexibility.

Innovative and versatile long anchor solutions

Key specification


  • Engineered with high-strength, stress-relieved, low-relaxation 7-wire steel strand cables

Key benefits

Cable Bolts

  • Ideal for high lift mines or high-stress environments
  • Can resist, absorb and suspend energy from rock bursts
  • Excellent control of squeezing rock areas
  • High static support stiffness yet allows for significant ductility once the yield limit has been exceeded
  • The paddles can act as mixers when used with resins
  • If a portion of the bolt fails, the remaining section retains functionality
  • Can be pre-tensioned when used with a mechanical end-anchor
  • Dynamic bolt installation mirrors that of standard bolts
  • Can be installed with manual hand-held equipment or mechanized bolting equipment
  • Can be coupled for longer lengths using a coupling version of the D-bolt®

Typical applications

  • Underground drifts and intersections
  • Mining stopes
  • Drawpoint reinforcement
  • Dilution control
  • Permanent openings
  • Civil and tunnel reinforcement
