Dust Suppression | Underground

Dust can have a significant impact on employees’ health, productivity and operational and maintenance costs. Chemstream has been a leader in the dust suppression industry by offering clients a choice of different D-Dust products that can match the coal/quartz dust conditions found underground.

How It Works
The addition of Chemstream products to a water system reduces the respirable dust generated at the face by up to 40%. Used in conjunction with the mine water system, it significantly enhances the suppression of dust, thereby lowering the airborne fugitive dust in the mine. Coal is a hydrophobic material, which causes it to repel water. D-Dust is a unique blend of specialized surfactants that lower the surface tension and the contact angle of the water allowing the water to more effectively wet the surface of suspended coal particles. Improving the wetting characteristics of the water allow the dust particles to become adsorbed and entrained into the water droplets, thereby reducing dust.


Improved Work Environment – The use of D-Dust products in underground operations has made significant improvements on the overall workplace environment. Because airborne fugitive dust is reduced, visibility is greatly improved for more efficient production and enhanced safety for miners.

Improved Equipment Performance – D-Dust products also offer an added value to underground operations through enhanced equipment performance. Our products unique chemical ingredients allow for spray nozzles and electric motor cooling jackets to stay clean and reduce build-up of scale, silt and other sediments in the operations piping system. Belts and belt scrapers work more effectively and remain cleaner with less water, enhancing the dust suppression without flooding the belt.
