Modeling of Fugitive Dust Emission for Construction Sand and Gravel
On the basis of the on-site measured data and an SAS nonlinear regression program, the expression of this model is E = 0.011·u 2.653 ·M-1.875 ·s 0.060 ·N 0.896, where E is the amount (kg/ton) of dust emitted during the production of each ton of gravel and sand. This model can serve as a facile tool for predicting the fugitive dust emission ...
