Abstract
The invention relates to cap or booster sensitive explosives for application in bulk or cartridge form in boreholes. The oxidizing salt of the explosive is ammonium nitrate, sodium nitrate and/or calcium nitrate having untamped bulk density of 0.3-0.7 g/cm.sup.3. The explosive can be a w-i-o emulsion explosive where the discontinuous phase is an aqueous solution of the oxidizing salts and where low density ammonium nitrate comprises 10-80 weight % of the total explosive. ANFO, HANFO and water-gel explosives comprising said oxidizing salts having untamped bulk density of 0.3-0.7 g/cm.sup.3 are examples of explosives according to the invention. The above types of explosives are especially suitable in small and medium size boreholes without using sensitizing or density reducing agents.
