Coal Dust Suppression System

Anglo American’s Grasstree Mine, near Middlemount, has revolutionised the way coal dust is managed in the underground environment with their innovative dust suppression system. It combines a poly-curtain spray, a continuous enviromist spray and most critically, applies a bio-degradable foam to coal as it moves through mining machinery. This is the first time the foam has been used in development coal mining and it's delivered dramatic results, with a 96% reduction in respirable dust exposure to development coal mine workers.

The system, which was conceived, designed, built and refined by the mine’s Development team, is now being implemented more broadly across the business and wider industry. It received the coveted innovation award at the Queensland Mining Industry Health and Safety Conference in 2018. Watch this video to learn more.
