Control of windblown dust from storage piles

This paper presents a strategy for developing more reliable estimates of the efficiencies of preventive methods for the control of windblown dust from aggregate storage piles The strategy is dependent on the availability of an experimentally verified emission factor equation which relates the particulate emission rate to wind speed pile surface properties and pile shape factors
