UniPass Dynamic Bolt

Engineered for dynamic and seismic ground, our one‑step, self‑drilling hollow bolt absorbs 20–50 kJ of energy and improves safe advance with CarboThix or cementitious grouting.

Product Benefits

One‑step self‑drilling reduces bolting cycle time and manual handling for safer advance

Defined yielding absorbs seismic energy, helping maintain support through dynamic events

20–50 kJ capacity provides confidence for headings exposed to rock‑burst risk

CarboThix resin enables early load and quicker re‑entry, improving productivity

Reduced annulus strengthens encapsulation and lowers overall grout consumption

Product Details

Minova’s UniPass Dynamic Bolt is purpose‑built for dynamic and seismic conditions, including zones at risk of rock burst. A one‑step, self‑drilling installation with a welded drill bit reduces the annulus, optimises grout consumption and accelerates bolting in unstable ground; pre‑drilled installation is also available when conditions allow. The bolt’s three‑section design – bond, defined yielding section, bond – delivers controlled energy absorption without compromising anchorage. Depending on configuration, the system provides 20–50 kJ dynamic capacity. Grouting through the hollow core with CarboThix bulk resin or cementitious grout ensures consistent encapsulation and early load, supporting safer, faster cycles and compatibility with semi‑ or fully automated bolting. UniPass Dynamic Bolt integrates seamlessly with UniPass accessories and our Drill–Inject–Go workflow to maximise safety, productivity and quality control underground.
