Latest Patents

Kjell Hanto holds a patent for water in oil emulsion explosives containing a nitrate salt. This invention relates to cap or booster sensitive explosives that can be applied in bulk or cartridge form in boreholes. The oxidizing salt used in the explosive is ammonium nitrate, sodium nitrate, and/or calcium nitrate, which has an untamped bulk density of 0.3-0.7 g/cm³. The explosive can be a w-i-o emulsion explosive where the discontinuous phase is an aqueous solution of the oxidizing salts. Low-density ammonium nitrate comprises 10-80 weight % of the total explosive. Examples of explosives according to this invention include ANFO, HANFO, and water-gel explosives, which are particularly suitable for small and medium-sized boreholes without the need for sensitizing or density-reducing agents.
