Next generation self-drilling injectable rock bolt system
Novobolt is a next generation self-drilling injectable rock bolt system providing all elements of the complete bolting process from the self-drilling rock bolt and anchorage chemicals through to the drilling and injection equipment.
Novobolt reduces the existing process down to a single step enabling the use of multiple options in bolt type, bolt length and injection volume.
The Novobolt range includes a standard bolt, a point anchored and pre-tensionable bolt (Cam Anchor), an extendable bolt up to 4 metres, and a cuttable bolt (GRP). All Novobolt options utilise the same processes and equipment for total installation.
The standard and pre-tensionable Novobolt drills a smaller diameter hole compared to other self-drilling bolt options, reducing the time taken to complete this largest time consuming step in the rock bolting process. The system as well
includes a resin pump station and reversible chuck.
Minova utilised a global resource to complete development of the Carbothix which is a fast curing two component silicate resin system designed specifically for injection bolts. When the two components are adequately mixed they form a tough elastic and non-porous resin that will not mix with water and be diluted in wet holes. Carbothix provides superior strengths to typical polyester resin systems, and is considerably lower in viscosity enabling easier
handling and long distance pumping.
