Modeling of fugitive dust emission and control measures

Both ambient dust concentration and occupational exposure level exceeded Indian National Standards at most of the locations. Mathematical models viz., FDM, ISCST3 and AERMOD were employed for prediction of dust emission from stone crushers on the surrounding areas. The impact zone for measured concentration varied 211–1350 m with a mean of 784 m.

Modeling of fugitive dust emission and control measures

2009-3-9  Stone crushing in India is a small scale industry, where most of the operations are performed manually. A cluster of 72 stone crushing units located at Trisoolam in Chennai is a source of high levels of dust generation in the vicinity of the crushers and in the communities surrounding them. An ambient air quality monitoring network was designed and operated over 3 months (June–August, 2006 ...
