1. Plastic Roof Mesh
Stratanet is a FRAS polypropylene roof mesh alternative to steel mesh.
- Improved visibility
- Reduced weight
- Stacks easily and effectively
- Corrosion resistant
- Module sizes can be tailored to meet mine requirements
- Non-conductive -ideal for use around the base of boreholes or shafts
- Replacement for standard mesh modules in development roadways
Underground trials have been undertaken at several underground coal mines in NSW with positive feedback from operators. Commercialisation is planned for 2019.
2. 20 psi Flexible Seal
WMS has under development a novel 20 psi flexible seal product aimed to meet an identified gap in the market for a cheaper alternative to cementitious type ventilation seals.To meet this need a 20 psi flexible seal product is under development. The fabric needs to have both high strength and flexibility as the primary load resisting element of the seal. It is intended for the fabric to also meet FRAS requirements. Fabric tests are being undertaken and are currently under review by a design engineer. There is a high level of market interest and an opportunity for a world first product.
3. OKA Self Drilling Bolt R&D Project
Self drilling bolts can deliver significant health and safety improvements, productivity gains and cost benefits to industry. Furthermore it is a key enabler to full automation whereby operators are completely removed from the roadway support process. Given the importance of roadway development for longwall mining operations and bord and pillar operations alike, a step change improvement in the roadway support process can have a significant impact upon the whole mining operation.
OKA Rock Bolt Technologies Pty Ltd (OKA Company) is a privately owned company established to develop and commercially exploit an innovative type of self drilling bolt known as the OKA Rock Bolt Technology (OKA bolt). The company has patented the OKA bolt and is about to undertake a production trial to prove the technology as an operating system. The core innovation is a novel injection system including pumpable resins. It is currently set up for semi-automation but with further refinement will allow full automation to current rock bolting systems.
The Australian coal industry (via ACARP Project C25058) has funded underground trials to prove the technology. WMS has provided labour and workshop facilities to assist with the trials.
