BLASTING CARTRIDGE Russian patent published in 2004 - IPC

Abstract RU 2242700 C2

FIELD: industrial blasting.

SUBSTANCE: the blasting cartridge has a through duct and a seat for the cap produced by filling-in of mixing explosive and is provided in the bottom area of the seat with an additional charge of high=order explosive. The novelty is in the fact that the mixing explosive represents trinitrotoluene with 42 to 18% of ammonium nitrate having a dispersity corresponding to the content of a fraction "less than 200μm" within 20 to 50%, and a fraction of " more than 630μm" within 5 to 15%, and its surfaces are coated with a layer of paraffin-petroleum mastic.

EFFECT: reduced cost of new blastic cartridges, thus enhanced their competitiveness.
