We innovate to improve the safety and productivity performance of our customers in mining. We offer a wide range of products and services designed for Australian conditions.
Our ground support solutions focus on delivering mine optimisation, productivity improvements and reduced risk profiles.
Our specialised products and services include:
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.

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.
Sprayed cements include wet and dry sprayed products which function as either structural or waterproofing membranes, offering simplicity and flexibility.
Our range of pre-blended products offer the simplicity and flexibility of dry spraying, which is ideal for applications where small volumes are needed, the timing of the application is unpredictable or the work site is constrained. We offer a range of sprayed coating and sealing systems for use in a wide range of applications. These include dry bagged shotcretes and speciality developed plasters.
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.
For more that 20 years we have manufactured a range of cementitious and steel fabricated systems that are used in the design and construction of underground mine ventilation structures and bulkheads.
In 1999 we diversified into contract design and installation of Ventilation Control Devices (VCD’s). Since then we have considerably expanded the range of products, devices and services available to the underground coal and metal mining industries globally. We offer the largest range of tested explosion rated VCD's and engineer rated devices specifically for underground mining
We offer vast experience and capability in engineering, design, product manufacture, fabrication and contract installation of VCD’s. We have successfully developed and implemented many specific devices for individual customer requirements.
Our range includes overcasts, machine doors (vehicle doors), man-doors, coffin seals, access hatches for seals, air-locks and consumables.
We offer our services in three ways:
