EMULSION EXPLOSIVE COMPOSITION FOR FORMING BLASTHOLE CHARGES Russian patent published in 2014 - IPC C06B31/28 C06B47/14 

FIELD: blasting operations.

SUBSTANCE: emulsion explosive composition (EEC) comprises as the oxidising phase the aqueous solution of ammonia and sodium or calcium nitrate and urea, and as the hydrocarbon phase the wax melt of fine crystalline or ceresin, individually or their mixture, with the emulsifier for industrial emulsion of explosives, individually or as specified emulsifier with tall oil rosin, oleoresin pine rosin, or their mixture, and as the sensitising agent - the aqueous solution of sodium nitrite, or polymeric microspheres or a their mixture. The effect of the invention is achieved by equilibrium ratio of components ensuring normalised density of emulsion matter equal to 1.00-1.20 g/cm³.

EFFECT: high explosive and operational characteristics, including physical stability of the EEC during prolonged storage, good sensitivity to the explosive pulse of standard primary means of initiation, small critical diameter, satisfactory propagation of detonation in the distance between the two cartridges, the high heat of explosion.
