Wilson Mining has released a new polypropylene alternative to steel mesh for roof and wall cladding applications in underground mines.
The Mastermyne-owned company describes Stratanet as a lightweight, corrosion-resistant and multi-directional high-strength alternative to steel.
A honeycomb design helps to distribute the load of any loose debris, having undergone several iterations to provide the highest flexural and tensile properties in the areas furthest from the supporting rock bolts.
The lightweight polypropylene – weighing in at 2.3-2.4kg/sq m – also provides occupational health and safety benefits associated with manual handling and installation.
“This innovative concept was developed through an identified need for this type of product within the underground coal industry,” Mastermyne Group consumables manager Gavin Welsh said.
Mr Welsh said the company believed Stratanet would be beneficial to the hard rock mining sector as well, which would further diversify the Wilson Mining offering to new markets and industries.
The product has undergone site trials and large-scale pull tests have been conducted at the University of Wollongong.
It is Australian made, manufactured in Victoria by Corex Plastics, a plastic extrusion and fabrication business who developed Stratanet in partnership with Wilson.
“It has been designed with associated patents & IP, from an engineering approach,” Mr Welsh said.
“This technological advancement in product development has been driven from years of experience in the underground coal industry and the desire to deliver more cost-effective and safer productive outcomes to our clients.
“Mastermyne is proud to give our clients access to a high quality Australian made and manufactured product; now more than ever it’s important the sector support products that are made in our own country.”
