Abstract. 

Iron ore is mainly mined by opencast method with massive explosions in the quarries, which are accompanied by emissions of dust and harmful gases and significant degradation of environmental safety in the region.

Environmental hazard of mass explosions in quarries is estimated primarily by level of near-surface concentrations of contaminants including dust on the border with or outside of the sanitary protection zone of the quarries.

Impact of the borehole charge parameters on technological and environmental results of the explosions were studied by a mathematical model with taking into account methods of industrial experiments planning.

Keywords:

iron-ore quarry, massive explosion, environmental safety.
