Rock Bolt Testing (Non-destructive)

Geohart have safely pioneered the use of non-destructive Rock Bolt testing to offer mining operations more detailed and accurate information and the added benefit of preserving existing rock bolt infrastructure.

rock bolt testingThe traditional pull out tests currently used for rock reinforcement testing is not considered an effective tool for the detection of compromised rock bolt systems used for ground control in underground mining and civil construction industries.

Pull out test still have an important role to play in determining critical bond lengths for static and quasi static ground support designs, however pull out tests do not provide an underground operation with any reassurance regarding rock bolt integrity, which could have been compromised during installation or affected by in-situ aggressive conditions.

Non-destructive rock bolt testing provides:

  • corrosion detectiontesting rock bolts
  • rock reinforcement integrity testing
  • resin / grouting quality control
  • site testing
Non-destructive Rockbolt Testing

Projects:

Geohart has been involved with non-destructive rockbolt testing for the last 8 years. The testing includes a range of rock reinforcement including friction stabilisers.
Geohart have been testing rockbolts at the following sites across the world:

  • George Fischer – Mt Isa (QLD) – XSTRATA
  • Sunrise Dam Gold Mine – Anglo Gold Ashanti
  • Fosterville Gold Mine – Victoria
  • Mandalong Coal Mine (Centennial) – NSW
  • CSA Gold Mine – Cobar NSW
  • Diftah Shis Road Tunnel – Abu Dhabi
  • Burrinjuck Dam – Hydropower Towers Footing Rockbolt Anchors – Yass NSW
  • Bridge deck Pre-stress Cables – TMR QLD
  • Boronia Tunnels – Sydney Rail
  • Oaky Creek Coal Mine – Glencore, QLD
  • Cliffs Nickel Mine – BHP, WA

The rockbolt testing includes the following type of bolts:

  • Resin solid rebar bolts
  • Single Strand Cable Bolts
  • Multi strand Cable Bolts
  • Splitsets / Friction Stabilisers
