Emission of respirable dust from stone quarrying, potential health
The site operations such as drilling, blasting, excavation, loading, unpaved road haulage, and primary crushing and stockpiling can cause substantial emission to the atmosphere. The uncontrolled emissions of fugitive dust can also cause significant environmental and health-associated concerns to the site-staff and the local community exposed to it.
