Technical Data

TD-Bolt undergoes regular in-house and periodic third-party quality control testing.

Note: The stated UCS values are typical of in-house testing conducted on 50 mm cubes mixed using Toowoomba Regional Council potable water, cast in steel moulds, and submerged-cured at 23°C. Performance-based properties, such as strength, working time, pumpability, etc, are highly-dependent on w:s ratios, mixer and pump type, addition of admixtures, and end-user applications and requirements. [1] Working time is defined as the total time available to mix, pump/apply, and clean out the mixing equipment (mixing bowl). [2] Performance achieved using a Clark Model M150 grout pump with 4 × 20 m lengths of 25 mm internal diameter air/water hose, with 60–70 psi air supply.

 TD-Bolt is a ready-to-use dry powder formulated as a high-strength, thixotropic cementitious anchoring grout for top-down grouting of cable bolts and long tendons in underground mining applications.Engineered for pumpability, high early strength, and non-shrink/expansive annulus fill, BMS TD-Bolt ensures consistent annulus fill and strong bonding for dependable ground support and performance in both competent rock and poor, fractured or broken ground conditions.

Features & Benefits

 Versatile Application: Suitable for vertical, overhead and horizontal sprayed ventilation seals and stoppings..

  •  High Early Strength: Minimises the risk of strata separation and/or slippage during early curing.
  • Thixotropic: Supports top-down grouting and performance in competent and poor ground conditions alike.
  •  Excellent Pumpability: Designed to pump over long distances to improve underground installation workflows.
  •  Safe: Non-toxic and non-flammable.

Typical Applications

 Top-down grouting of cable bolts and long tendons in underground coal and hard rock mines. …

  •  Top-down grouting of cable bolts and long tendons in underground coal and hard rock mines.
  •  Stabilisation of roof strata in development headings and production panels, particularly where early support capacity is desirable.
