Blast parameters and geology also influence them. Appropriate blasting can reduce gener ation of fines and ejection of dust and fines during blasting. Another step is to stop fines getting air borne. Modelling of dust plume and difficulties in measurements to quantify dust dispersal through a particular area are de scribed.
