Steel and glass fibre reinforced polymer bolting products and accessories to stabilise even the most stressed ground.
Friction bolts have been used internationally in mining for decades and are considered the simplest form of ground support available in metal mining. Compression of the high tensile steel "C" shape into a hole diameter smaller than the tube generates a load transfer from the steel to the rock. A steel ring is fixed to the collar end of the tube that will retain a plate on the installed tube to establish compressive force against rock.
Available in either black or hot dip galvanised. Variety of diameters (34 mm, 40 mm and 47 mm) and various lengths from 600 mm to 3,000 mm
Used in the development and production headings for immediate support with quick and easy installation.
The Secura Bolt is a solid reinforcing bar for use in strata environments of underground mines. Design includes a unique paddle system to improve resin mixing and resin film shredding. Consistent and efficient mixing of resin capsule components provide higher bond strength in large diameter boreholes
The solid reinforcing bar is threaded at one end with a high strength R thread profile, including a modified rope thread with large root and small crest areas. A torque nut is attached at this end. Available in various lengths and can be supplied black or hot dip galvanised.
Variants available:
R24 Secura Bolt
R24 Secura Debonded Bolt

Surface support coverage providing increased safety.
Mesh provides surface support coverage to loose rock between installed rock bolts in underground mining excavations. Multiple configurations of mesh is available including numerous sheet sizes, apertures, wire diameters and black or galvanised wire.
Ausro straps are yielding straps which allow the straps to yield under load conditions allowing better load distribution between bolts. Ausro straps are used in unstable ground conditions where seismic activity is present, to improve surface support and ensure better connection between the surface support and bolts.

Injection chemicals used for stabilising, sealing and consolidating the ground.
Bevedol® / Bevedan® is a two component, foaming polyurethane (PUR) injection system used to consolidate highly convergent strata. The system consists of a resin (Bevedol®) and a catalyst (Bevedan®) which is delivered into the strata via a pump unit and injection gun. The two components mix in the gun, which initiates the reaction of the product. The low viscosity mixture penetrates the smallest fissures, hardens and ensures the consolidation and sealing of the area submitted to treatment.
Carbofill® is a two component phenolic foam resin used for filling cavities. Component A is an aqueous phenolic resins containing a suspension of solid carbonates as a blowing agent and Component B is a blend of various acids which affect the foaming process and the curing reaction.
The final product is a lightweight material with a yellow to pink colour. Ideal for filling of cavities in underground roadways and longwalls and the stabilisation and prevention of gas accumulation, stabilisation of debris and forming temporary plug seals.
Sprayed coatings and membranes provide additional ground support and waterproofing solutions.
Rappass offers high performance, abrasion resistance and rapid strength. Rappass C, a special concrete mix requires the addition of water to produce a flowing concrete consistency. Rappass GD is a specially blended cement that is applied by dry shotcrete processes. Uses include lining ore passes, outfalls, spill ways, draw points, crushers and chutes.
Supplied as a pre-packaged coarse dry powder in 20kg bags. Sprayed with the addition of water using dry shotcrete process. Sprayplast can also be used for scat control and ventilation control.
Cement based spray material designed with excellent flexibility, high tensile strength and excellent adhesion qualities. Tekflex powder is added to Tekflex liquid through a specially designed pump system for a continuous mixing and spraying operation.
Used to permanently stabilise the integrity of rock structures while accommodating the stresses associated with strata movement and providing a barrier to moisture degradation. Tekflex was developed for specific use as an alternative to the use of steel mesh for scat control in underground mining excavations.
Resin capsules and cementitious grouts stabilise rock and provide support when you need it most.
High strength, thixotropic anchoring grout used for top down grouting, grouting of long tendons and consolidation.
Ready to use, free-flowing, blended cementitious powder that only requires the addition of water in a high shear mixer, to produce a highly thixotropic grout.
With the addition of FB400 + to our range, you can now grout cables 100m away from the grout pump is located using Minova's industry leading grout
Two component grouting resin for cable bolt anchoring and self drilling bolts. An instantly thickening, fast curing, two component silicate resin for high strength bonding of solid bolts and cable anchors. The final mixture thickens very quickly to form a tough, interpenetrating non porous elastic silicate. This minimises leakage from the bolt hole, displacing drilling water helping ensure full encapsulation.
Carbothix has been designed especially for use with our range of UniPass dynamic and static rock bolts. Tested in Australian conditions, Carbothix allows for improved rock bolting productivity.

Largest range of tested explosion rated ventilation control devices.
For more than 20 years we have engineered, designed, supplied and installed steel ventilation control devices (VCD's).
Our steel VCD products and service solutions are customised to suit our customer’s site specific requirements and engineered to conform with the requirements of underground coal mine legislation. Our focus is to continually offer VCD product designs which are safe to handle and improve installation times. All VCD’s are equipped with convenient and rated lifting points, allowing easier and safety handling during installation.
To ensure the longevity of our products, all steel structures are sand blasted and coated with a high build acrylic resin applied directly to the bare steel as a combined primer and topcoat. Two-coat epoxy paints and galvanizing can be also provided on request.
We supply overcasts, machine doors (vehicle doors), man-doors, coffin seals, access hatches for seals, air-locks and consumables. We also provide 2, 5, 20 and 50 psi rated steel VCDs including consumables cast into stoppings, goaf seals and formwork systems (Tecmesh and Meshblock).
To help ensure clean air in underground mines we offer a range of solutions that include automatic airflow regulators, secondary air control and plastic regulator drop boards.
In 2005 we developed a revolutionary new automatic airflow regulator, Blastflow®, for Hard Rock mines that can be retrofitted to existing regulator sites. Secondary fans can be combined with automated Blastflow regulators to allow the mine to control where and when air is placed. Ventilation on Demand (VOD) allows an underground mine's ventilation circuit to be electronically controlled delivering airflow efficiency, reduced electricity and rapid access to production areas.
To control air flow at stope accesses and draw points, ore passes and the general direction of ventilation throughout mine areas we offer ventilation blinds (QBC). Designed to suit specific size openings and can be relocated for re-use.
To control air quantities in an underground mine circuit we offer environmentally friendly, recycled plastic drop-boards.
