DUST. Mining activities are synonymous with dust generation. Primary dust generating operations include drilling, blasting, crushing, and the milling of mined ore, amongst others. The respirable fraction of the mineral dusts such as rock, stone, and concrete, which in most cases is not visible to the naked eye, may reach the alveolar region of ...

Wet dust control methods for crushing operations, involve wetting the process material before crushing, after crushing, or both. This is essentially treating the crushing operation as two transfer points, the feed side and discharge side. The nozzles used depend by type of control, Hollow cone nozzles should be used when dust suppression (reduction of airborne dust) is desired, with spray ...

If control technologies are inadequate, hazardous levels of respirable dust may be liberated into the work environment, potentially exposing workers. Accordingly, federal regulations are in place to limit the respirable dust exposure of mine workers. Engineering controls are implemented in mining operations in an effort to reduce dust generation and limit worker exposure.
