The ManziBolt is very similar to the Hydrabolt except that the ManziBolt is inflated between 15MPa to 17MPa upon installation which alters its performance specifications. This allows the ManziBolt to be installed in hydropower mine shafts without the requirement to intensify the water pressure.
The ManziBolt is visually differentiated by the green coloured connector button (rather than the gold Hydrabolt button) and the square shaped indicator inside the filler hole.
The ManziBolt supports the hanging wall by expanding along its full length and bonding to the rock by friction. Its unique features are ease of installation (ergonomics) and its self-auditing features. Apart from the Hydropower installation, the installation sequence of the ManziBolt is the same as the Hydrabolt.
All of New Concept Mining’s Inflatable Bolts can be offered with Thermal Zinc Diffusion for improved corrosion protection if required.
