Cable Rock Bolts

Cable bolts offer significantly higher strength compared to traditional bolts, along with unparalleled flexibility to accommodate the movements of the earth’s strata.

Product Benefits

Higher roof stability in weak or moving strata
Faster installs using existing bolting machines
Improved anchorage and load transfer with bulbing
Select reels or cut lengths to streamline underground logistics
Configurable passive or post‑tensioned support

Sectors

Metal & Non-Metal Mining, Coal Mining

Applications

Roof control, Bottom up grouting, Rock bolting

Product Details

Minova’s cable bolts deliver high‑capacity, long‑tendon ground support engineered to perform even when strata move laterally, giving you reliable reinforcement where standard support is insufficient. Our exclusive bulbing enhances resin mixing and anchorage, working seamlessly with Minova resin cartridges for rapid, consistent installation. Systems are available as passive or post‑tensioned solutions, in bright or galvanised strand for extended stand times beyond one year. To match your mining method, we supply cable bolts as cut‑to‑length units or continuous coiled reels. Metric strand diameters include 15.2 mm (0.6 in) and 17.8 mm (0.7 in) options, with approximate ultimate loads of 27 tonnes (30 tons) and 36 tonnes (40 tons) respectively. Boreholes typically use 25 mm (1 in) or 35 mm (1‑3/8 in) diameters. Installation uses existing bolting equipment and low‑profile fixtures for any seam height, helping reduce cribbing, improve ventilation, and reinforce the roof for safer, more productive operations. Common application areas include tailgates, bleeders, headgates, intersections and recovery rooms.
