Minova Secura DB Bolt is a high-deformation rock support solution engineered for underground environments exposed to seismic activity, rock bursts, and squeezing ground. Designed in collaboration with mining and geotechnical experts, it features a dynamic elongation zone that absorbs axial movement and retains load-bearing capacity during large deformations. The bolt integrates seamlessly with Minova’s Lokset resin capsule system, using mixing paddles for optimal resin bonding and anchoring.

Available in 20 mm and 22 mm diameters, it offers tensile strengths up to 240 kN and dynamic energy absorption exceeding 100 kJ. Manufactured from high-strength, high-ductility steel, and optionally hot dip galvanised for corrosion resistance, the Secura DB Bolt ensures fast installation, reliable performance, and long-term stability in challenging ground conditions. It is ideal for tunnels, shafts, and deep mining operations where safety and adaptability are critical.
