Darling Irrigation provides optimal dust suppression solutions for mining clients as well as managing the water capture, recycling and delivery systems required for continuous supply water. We offer effective dust suppression systems for the mining industry through either wetting or airborne capture methods.
Dust Suppression Systems
Dust in a mining operation presents one of the most visible and invasive operational constraints. Not only is it a nuisance problem but it can raise a number of health, safety and environmental concerns.
Dust is an inevitable consequence for the mining industry as a result of blasting, drilling, processing and transporting activities.
Dust suppression through wetting
Wetting broken or fractured material helps dust particles stay attached and minimises release into the air. Water on a mine site can be difficult to manage and it is often hard to obtain the quantity of water required to suppress dust. As a result, the design of any wetting dust suppression system is vital.
Darling Irrigation can design and install dust suppression systems using fixed or mobile sprinkles, water spray or irrigation systems and ensure water volumes are optimised by guaranteeing the system delivers uniform application and timed automation of the water application.
Dust suppression through airborne capture
Airborne capture of dust particles is both an alternative and complementary method of dust suppression to wetting. Using high pressure water sprays with specifically designed droplet size and under conditions of high uniformity, dust particles can be captured and effectively ‘taken out’ of the air to be held within falling water droplets. Suited in specific applications, Darling Irrigation can assist mining sites with the design and installation of airborne capture systems for dust suppression.
Increasing dust suppression effectiveness
Wetting agents, such as foam, has been proven to be very effective in aiding in the capture of dust particles where there is a limited supply of water.
