Abstract
A method and apparatus for the placement of emulsion explosive compositions is provided which substantially reduces the amount of work which must be expended to pump the explosive emulsion through a conduit and into a detonation site. This is accomplished by providing a substantially annular stream of a lubricating fluid such as water around the emulsion explosive being pumped, said stream being injected at a flow rate such that the linear velocity of the lubricating fluid is substantially the same as that of the emulsion explosive being pumped through the conduit.
