MODIFIED EXPLOSIVE MATERIAL Russian patent published in 2017 - IPC C06B31/28 C06B45/04 F42D1/10 

FIELD: chemistry.

SUBSTANCE: invention relates to an explosive composition containing an aqueous emulsion of: 94 wt % of an oxidizing component comprising an aqueous solution of ammonium nitrate, 6 wt % of a hydrocarbon fuel component containing an emulsifier, and also a sensitizer and/or a dry additive - ammonium nitrate granules, and a filler, which is a waste material of a combustible type, namely a plastic, rubber, paper, cardboard, wax material, mixed waste plastic. The composition comprises, at least, 50 wt % of emulsion and from 1 to 50 wt % of the filler. The waste material itself does not provide emulsification sensitization and is a solid powdered material formed into dry granules that do not have rough surfaces and sharp edges so as not to cause emulsion crystallization having a size, shape and fluidity similar to that of ammonium nitrate. The invention also includes a method for delivering an explosive composition to the explosion place using a mobile unit (MPU), which is a vehicle having separate compartments adapted to separate the contents of liquid fuel, solid waste particles, and an ammonium nitrate-based emulsion. Also a method of blasting soft and wet ground is included, comprising the delivery of an explosive composition to the explosion place with a mobile unit (MPU), pumping the composition into blastholes and undermining it.

EFFECT: invention allows the disposal of waste that is intended for landfill or incineration, with the production of blasting explosives.
