Dust Suppression

Dust can have a significant impact on employees’ health and productivity as well as operational and maintenance costs. Inadequate dust control can also have significant environmental impacts to surrounding communities. Chemstream is uniquely positioned to provide products that are suitable for underground mining as well as surface mining and roadways applications.

Chemstream has been a leader in providing dust suppression products to various industries for years. Our extensive experience in dust suppression will help you select the right product, proper injection equipment and most convenient product package.

Underground Mining Applications

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 allows 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 in 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.

  • Dust Suppression Products and Equipment

Chemstream has a collection of high-performance products that are customized to fit your exact dust suppression needs.

  • Dust Suppression Equipment

Chemstream can inject D-Dust directly into the mine water system in either individual sections or in a mine wide format.

Roadway Applications

  • Dust Suppression Products and Equipment

Road dust suppression is typically applied with a water truck. We can supply the product to use in your trucks or we can quote a turnkey job using our equipment and manpower to maintain your roadways.
