Abstract
A mobile manufacturing and delivery platform that is adapted to provide in a blasthole an explosive composition comprising a liquid energetic material and sensitizing voids, the sensitizing voids being present in the liquid energetic material with a non-random distribution. The platform comprises a storage tank for the liquid energetic material; at least two delivery lines for conveying respective streams of the liquid energetic material from the storage tank; a void delivery system for producing sensitizing voids in at least one of the streams of liquid energetic material; a mixer for mixing the streams of liquid energetic material to produce the explosive composition; and a blasthole loading hose. The mixer may be provided at the end of the loading hose. A blasting method employs the platform to manufacture and deliver the explosive composition into a blasthole, which composition is subsequently detonated.
