Abstract. The carried out research has discovered that changing conditions of detonation of emulsion explosives (EE), in particular the charges spaced with an inert interval, cause changes in the composition of detonation products and increase the emission of pollutants into the atmosphere. Moreover, detonation evolution conditions in a model emulsion explosive charge with inert intervals of various designs have been estimated. It is shown that the violation of the sequence (or synchronicity) of initiation of spaced charge elements leads to densification of that part of the charge which detonates with a delay. Consequently, it shows reduced velocity and pressure of detonation, which ultimately leads to an increase in emission of pollutants into the atmosphere, in particular carbon monoxide. At the same time, the dependence of its concentration on the reduced density of the emulsion explosive has been found. Minimized emissions can be achieved by optimizing the design of an inert interval, or improving the system of initiation of emulsion explosive charges.

Keywords: contamination substances content, emulsion explosives, spaced charge, composition of detonation products
