Abstract: Manufacturing of non-explosive components of explosives and the use of emulsion explosives in the vicinity of the blast sites is a topical problem for blasting operations in both underground and open-pit mines. The article analyzes the insitu consumption of industrial explosives and identifies the main features of emulsion explosives that distinguish them from other types of industrial explosives. Manufacturing of emulsion explosives is exemplified by the experience of AZOTTECH LLC in production of non-explosive components of explosives in special modular units, transportation of components in mixing and charging machines to the blast sites and creation of emulsion explosives using proprietary recipes in the same mixing and charging machines. The process of manufacturing the emulsion phase with a pressurized dynamic mixer, i.e. colloid disperser, is taken as the core step in production of non-explosive components of explosives in a modular unit. The paper provides information on the selection of the emulsifying machines (static without pressure), reviews their differences, and analyzes their design, key parameters and operation during the emulsifying process in the colloid disperser. Specific features of the process mixer are studied as well as pressurized dynamic mixers and dynamic mixers used in the emulsion phase production, which shows that the use of this type of dispersers makes it possible to obtain the matrix phase with a wide range of characteristics that expand the scope of application of emulsion explosives to meet different customer requirements.
