Steel Fabrications

Minova has provided the mining industry with steel fabricated VCD’s for more than 15 years.

All VCD's are assessed by Registered RPEQ (Professional Engineers of Queensland) ensuring the highest levels of safety are met for each design. Engineering design is undertaken to AS 4100 (Steel Structures Standard). Certifications can be supplied for all steel fabricated VCD’s where legislation requires it.

To ensure the longevity of our products, all of Minova’s 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.

Minova is able to provide all 2, 5, 20 and 50 psi rated steel VCDs including consumables cast into stoppings, goaf seals and formwork systems (Tecmesh and Meshblock).

All of Minova’s VCD’s are equipped with convenient and rated lifting points, allowing easier and safety handling during installation.

Overcast Systems

The Minova overcast systems provide a tried and tested method to separate air paths, preventing contamination. The overcast system can incorporate other ventilation control devices including man doors and air locks into its design. Minova provides both gypsum and cement based shotcrete (wet mix or dry bagged product) for sealing the overcast to the roadway periphery. Modular overcasts are supplied in an arrangement that incorporates the hinged wall and roof sections in a single flat pack. Read more

Vehicle Access Doors

Available with two or three hinged leaves and each set of machine doors has an air relief slider which are able to be configured for manual and pneumatic operation. Minova can supply pneumatic controls for coal mine vehicle access doors. Pneumatic controlled ventilation doors remove the risk of injury caused by manual operation, increase productivity and have lower installation costs compared to hydraulic systems. Read more

Man Doors

Man doors are designed to be installed into sprayed stoppings. Access hatches are available in various thicknesses to suit ventilation seal designs. The hatch is designed for an overpressure rating of 50 PSI prior to concrete filling and are designed so that the doors can be shut while the operator is outside the hatch. Once the installation is complete and all the doors have been bolted shut, the hatch can be left for filling at a later time through filling ports. Read more

Air Locks

A standard 5 psi air-lock has dimensions 3 m length x 2.0 m height x 1.5 m width with 1.5 x 1 meter man doors. Air-locks can be supplied as a flat pack unit for easy assembly on site or as fully assembled units. Read more
