Source data The source data required as model input
are the locations of various sources of SPM in
the mines, their dimensions and emission rates. For
cumulative impact assessment it is sufficient to have
only approximate locational and design information
for the other mines since detailed designs may not be
available at the stage. Location and dimension details
were obtained from the digitized maps in GIS.
Emission rates for different types of sources were
calculated using formulae given in Table 5.
