Abstract: The article discusses the sensitiveness to impact of industrial emulsion explosives, which is an important characteristic affecting safety during the blasting operations. Experimental values of sensitiveness to impact indicators were obtained using the Berezit® Grade SB-1 samples in the form of acidified emulsion matrix, a gasified emulsion and a substandard emulsion. The results of the studies showed that, within the scope of the conventional methods according to GOST 4545-88, only the gasified emulsion was sensitive to impact, with an explosion frequency of (16–24)%. It was established that under the free flow conditions, the samples were not sensitive to impact when a 10 kg load was dropped from a height of 500 mm. Under the conditions of restricted flow, even the acidified emulsion matrix proved to be sensitive to impact. In addition, the flow pressure of the Berezit® industrial emulsion explosive was determined to be 0.48±0.05 GPa, above which blast initiation takes place.

Keywords: explosives, industrial emulsion explosives, energy-intensive emulsions, explosion frequency, lower limit of sensitiveness to impact, critical initiation pressure
