Abstract (en)
[origin: EP2360133A2] A method of producing an emulsion explosive for use in an underground mining operation is provided. The method includes feeding, by means of gravity, an emulsion explosive oxidizer from an oxidizer source to an underground oxidizer holding zone in a mine, while separately feeding, by means of gravity, an emulsion explosive fuel from a fuel source to an underground fuel holding zone in the mine. Oxidizer and fuel are withdrawn from the oxidizer holding zone and the fuel holding zone respectively, and separately fed, under gravity, to an underground emulsion explosive production zone which is thus located at a lower level in the mine than the oxidizer holding zone and the fuel holding zone. An emulsion explosive is produced by admixing the fuel and the oxidizer in the emulsion explosive production zone.
