Abstract
Disclosed is a method of pumping and preventing plugging for water-in-oil emulsion explosives within conduits in which the pumping is interrupted and a lubricating fluid is used that moves in an annular stream around the emulsion. The lubricating fluid provided by the invention which comprises an aqueous salt solution allows interruption of the pumping without the occurrence of plugging in the conduit.
