The present invention relates to an emulsion explosive of the water-in-oil type having resistance against dissolution in water, and application of said emulsion in explosive mixtures. The emulsion explosive is non cap-sensitive and can be cartridged alone or in mixture with ANFO. It can also be used in bulk systems. The explosive contains 60-90 percent by weight of ammonium nitrate and calcium nitrate, 4-15 percent by weight of a crystallization temperature lowering agent, preferably urea, and 2-6% wax and/or a wax/oil mixture. The content of water consi...
An emulsion explosive of the water-in-oil type comprising: a total of 60-90 percent by weight of both ammonium nitrate and calcium nitrate; 4-15 percent by weight of a crystallization temperature lowering agent; an emulsifier; a density reducing agent; and 2-6 percent by weight of at least one hydrocarbon fuel selected from the group consisting of wax and oil; wherein the content of water in said explosive substantially consists of water of crystallization bound to said calcium nitrate.
