METHOD FOR PRODUCING OF EXPLOSIVE MIXTURE AT BLASTING SITE Russian patent published in 2006 - IPC C06B47/14 C06B31/28 C06B33/04 

FIELD: manufacture of industrial explosives.

SUBSTANCE: method involves continuously preparing and pumping out explosive mixtures at blasting site and simultaneously filling wells adapted to be blasted. Method includes following steps: delivery of explosive components to preparing site, namely, non-explosive material or low-sensitive matrix material containing, in aqueous solution or in suspension, oxidizing salt, thickener and, optionally, inflammable material and/or sensitizer, and air bubble stabilizing material and, optionally, granulated inorganic oxidizer, and/or liquid inflammable material; mixing components in rotary-type mixing unit which is adapted for adjustable drawing of atmospheric air to produce explosive mixture with oxygen balance of from -10% to +10%.

EFFECT: increased efficiency and improved quality of explosive mixtures provided through regulation of density by introducing regulated amounts of atmospheric air into explosive mixture.
