Research and development of software and hardware modules for testing technologies of rock mass blasting preparation

Abstract

Calculation of ecologically harmful substances diffusion into the atmosphere from ventilation shaft of iron-ore mine that situated within city is executed. Isolines of near-the-ground concentrations of total impact of ecologically harmful substances around contamination source that change with distance increasing from ventilation shaft on exponential dependencies are given. Empiric formula that allows to determine near-the-ground concentration of total impact of ecologically harmful substances with taking into account explosive ratio and distance from emission source is established.
