INDUSTRIAL EXPLOSIVE SUBSTANCE Russian patent published in 2014 - IPC C06B25/24 C06B31/48 

FIELD: chemistry.

SUBSTANCE: invention relates to the field of industrial explosive substances (IES) based on powders, used as well charges in the mining industry and construction. The composition contains, wt %: as a sensibiliser, utilised ballistite solid rocket fuel or ballistite powder based on nitro-glycerine, in the form of chips with dimensions from 1.0 mm to 20.0 mm, with the number of particles, which are not larger than 5.0 mm, being not less than 60 wt %, the surface of which in the process of crushing is covered with a silicon oil film, in an amount of 3-10% of the sensitiser weight - 35-60. As an oxidiser the composition contains granulated or crushed ammonium nitrate 40-65, and as liquid fuel, industrial oil, instrument oil, rapeseed oil, black oil or Diesel fuel 3-15 above 100 wt %. The composition is intended for carrying out explosive works on the ground surface, by a method of well charges in the temperature range of the environment from minus 50 to plus 50°C, in wells of any degree of water cuttings, including with flowing water.

EFFECT: invention ensures an increased level of IES application safety, on the basis of utilised ballistite solid rocket fuels and powders, containing nitro-glycerine, due to the prevention of nitro-glycerine exudation on the surface of the powder elements, as well as ensures physical stability, increased energy and ecological characteristics of IES due to the balance of content of the oxidiser and fuel and optimisation of dimensions of the powder particles.
