UniPass bolting technology combines leading-edge and high-quality, high-strength products to make rock bolting safer, faster and more efficient.
► Next Generation Bolting
UniPass bolting combines our static, yielding and dynamic hollow bolts and Carbothix bulk resins to provide an all-in-one bolting system that has been engineered to suit the most demanding requirements of underground mining. The immediate bonding of the resin makes it possible to load the bolts without leaving the borehole, dramatically increasing bolting speed and worker safety.
► Installation Flexibility
The UniPass system can be installed in a one step operation by using our self-drilling bolts. The system can also be installed in pre-drilled holes (two step process). UniPass is adaptable to varying ambient temperatures, humidity and ground conditions.
► Automating Mines
The UniPass bolting system has been designed with semi- or full- automation of ground support installation in mind.
Mesh provides surface support coverage to loose rock between installed bolts. Mesh variants include steel welded mine mesh, ausro straps, Glass Fibre Reinforced Polymer (GFRP) mesh and polypropylene mesh.
We have manufactured Lokset resin capsules since the late 1960's and are the leading supplier and innovator in this field. Australian development and manufacture ensure security of supply, service and support.
The Lokset system consists of an easily handled cartridge, containing a highly reinforced polyester resin component, together with its catalyst, in accurately measured quantities. The rotation of the bolt during installation ruptures the capsule, shreds the skin and mixes the two components causing a chemical reaction and transforming the resin mastic into a solid anchor.
The Lokset resin capsule series is available in multiple configurations of single/double length combinations, diameter, set time, set time combinations, viscosity and shelf life.
The oldest reference Minova has for Lokset® resin anchors was the strengthening of the London Heathrow Airport road access tunnel in 1963 to allow heavy jets to land. Since then there have been numerous applications across the world in mining applications, highway tunnels, civil applications and a submarine base.
We have been committed to global research and development since the mid-1980's. We range a comprehensive selection of rapid strength, cable bolt grouts for general and specific bolting applications. Our grouts are ideal for cable bolt grouting in underground and surface mine applications.
Our tried and tested anchoring grouts are supplied pre-blended and pre-packed requiring only the addition of set amount of water in a high shear mixer to produce high quality grouts.
Applications may include;
Thixotropic grouting, long distance pumping, water stop grouting and rapid advance drill and blast development.
Which grout is right for you application?
Our high volume output grouts produce significantly larger outputs than traditional cement grouts. This is beneficial as significantly less amounts of physical materials are required to be transported. Product range includes numerous foaming and non-foaming grouts.
Applications include; explosion resistant ventilation seals, underground cavity filling, collapsed roadway recovery, backfilling behind steel sets and sidewall stabilisation, rockfill consolidation and pillar support.
Which grout is right for you application?
Our injection chemical range includes polyurethane (PUR), silicate and phenolic based systems. These systems are routinely used to stabilise longwall faces in underground coal mines and prevent falls of ground during production. Polyurethane products can be injected under high pressures and have a long history in preventing water ingress of varying magnitudes into the mine.
All our strata injection and cavity filling chemicals used in coal mines hold the German Authority permit (LOBA compliant), an internationally accepted standard for the safe and correct manufacture and application of these systems.
Ground support solutions are essential foundations to the safety of underground operations are used in almost every mine today.
Rock reinforcement include methods that modify internal rock mass behaviours by installing structural elements that prevent further rock mass loosening, reduces deformation caused by excavating and stabilises the rock, extending the natural rock arch. This type of reinforcement is an active method of support that includes point anchored bolts, friction bolts and grouted bolts.
We offer a full range of solutions that address the requirements for increased life cycle, ranging from stainless steel bolts to specialist coatings and new technologies. We offer multiple coating solutions for a wide range of bolts that increase bolt lifespan while maintaining bolt performance. Due to varying geological conditions and project applications, a single bolt is unlikely to meet all requirements.
