Loaded rail wagons leaving New Hope Group’s New Acland Coal Mine in Queensland are being veneered by a solution known as RT4 Superskin, in an effort to suppress environmentally harmful dust emissions.
RT4 Superskin, designed by Australian dust suppression and soil stabilisation company Reynolds Soil Technologies, is diluted in water and sprayed directly onto the surface of loaded coal.
The water-based dust suppressant crusts and binds the coal’s surface layer to create a durable veneer coating, aimed at preventing the movement of dust and fine particles throughout the transportation phase.
Key to the project was Queensland based civil engineering company Shadforths Civil Contractors, which designed and built the new rail wagon veneering system at New Hope Group’s Jondaryan Rail Loading Facility, located west of Toowoomba.
Through one automated spray application during the loading process, coal fine particles are tightly suppressed as the water dispersive polymers dry, according to Reynolds.
This process ensures that New Hope Group is complying with Queensland’s Coal Dust Management Plan and meeting the Department of Environment and Heritage Protection’s standards.
“Our RT4 Superskin product is a highly effective, non-hazardous dust suppressant specifically developed for the minerals transportation industry,” said Reynolds Soil Technologies’ operations and technical director David Handel.
“Comprising the latest in eco-friendly chemical technology, RT4 is both easy and efficient in application and is also a cost-effective alternative to covering the coal wagons with materials and lids. The strength and durability of the RT4 solution will also prevent the veneer coating from cracking throughout travel.”
