Studying detonation of commercial emulsion explosives using the electromagnetic method

The article reviews a study of the detonation characteristics of commercial emulsion explosives, which play an important role in blasting operations, using the electromagnetic method. Obtaining the reference values of detonation characteristics and validation of the method were carried out using samples of Berezit® E-100 grade in charges inside 45 mm PVC pipes. As the result of these studies, a method of studying the detonation characteristics of commercial emulsion explosives using the electromagnetic method was developed. Reference profiles of changes in the mass velocity of the detonation products were obtained, which are necessary for subsequent studies in a larger diameter charges, taking into account changes in the formulation and manufacturing methods of the industrial emulsion explosives. The lack of a pronounced chemical peak has been established, which is characteristic of the water-based compositions. The reasons of this phenomenon are of great scientific interest, and considering the direct effect on the generated pressure and consequently the results of rock crushing, they lay the foundation for improving the formulations of commercial explosives.
