Dust Dispersion Modeling of Mines by Wind Characteristics.

      Аннотация: The main objective of the book is "Dust dispersion modeling of mine dust carried by the wind". The purpose of a dust dispersion model is to provide a way to calculate ambient ground-level concentrations of an emitted substance if information about the emissions and nature of atmosphere is given. In order to assess whether an emission meets the ambient air objective, it is necessary to determine the ground-level concentrations that may arise at various distances from the source. This is the function of a dispersion model. Therefore, this book has been planned with following objectives:(i) Evaluation of source term for open cast mining activities.(ii) Estimation of emission factors from different dust generating operations like drilling, blasting etc. in open cast mines.(iii) Using the emission source term for predicting dust levels in and around open cast mines by dispersion modeling.(iv) Collection of metrological data at mine site and analysing wind characteristics & frequency distribution.(v) Dust monitoring at different locations in and around open cast mines in three seasons using High Volume Dust Sampler and dust dispersion modeling using collected data.
