Mine Ventilation Ducting — Reliable Solutions By Plascorp

When it comes to mine ventilation ducting, it is imperative that the underground ventilation system is of the highest quality to guarantee maximum effectiveness and safety. Without this, your site poses the risk of putting workers in danger. However, with Plascorp, you can rest assured that our mine ventilation solutions are some of the best in Australia.

At Plascorp, our mining products are constructed from polyethylene woven coated fabric or polyester coated PVC. Our manufacturing process incorporates our patented process stitchweld mineflat. This innovation gives vastly reduced air loss by way of top and bottom welded seams. In addition to this, inventory rationalisation can be achieved.

Our stitchweld product has demonstrated a longer lifespan compared to other competitors. By eliminating weldtear and delamination, our unmatched product has quickly become the go-to mine ventilation option and is used in mines all over the world.

Industry Leading Ventilation Ducting

Plascorp can supply you with all your ventilation needs, to install a new ventilation system for underground mining or industrial applications. For the most reliable underground ventilation system possible, make Plascorp your next choice.

In addition to mine ventilation, Plascorp offers a range of highly-effective ducting. From flexible ducting to composite hosing, for over 50 years we have been providing Australia and the rest of the world with top-quality products and materials.

MINEFLAT

Based on field tests, Mineflat delivers more airflow for a given length of ducting due
to a lower leakage coefficient because of our patented stitch-weld process. Mineflat
is colour coded based on the diameter of the duct to easily identify sizing.

All sizes available in 5, 10 and 20m lengths with some also available in 50m. The joining
mechanism is the skirt connecting method consisting of eyelets and a skirt enabling
connection with Mineflex, hook and loop fasteners and even zippers. Discuss with your
Sales Representative for your joining needs.

MINEFLEX

Mineflex typically is constructed with Minemaster fabric. As the name “flex” indicates,
this product has a wire spiral helix which provides flexibility and avoids kinking.
The joining mechanism is the skirt connecting method consisting of eyelets and
a skirt enabling connection with Mineflat. This product is available in all material
types described on page 2. Other diameters and lengths available upon request.

TWINDUCT TRANSITION / TROUSER LEG

The Twinduct Transition and Twinduct Trouser Legs (shown) convert a single Mineflat
duct into a Twinduct without losing airflow volume. Easily connects to existing Mineflat /
Mineflex and Twinduct. Selection is based on headspace and ventilation
line requirements.

DUAL FIN BRANCH PIECE

Used when a side tunnel diverts off the main tunnel. The branch is at 45° to the main
vent. The double hanging eyelets or ‘DUAL FINS’, allow the branch piece to be installed
left or right, simply by inverting it.
