Abstract

According to the present invention there is provided a method of preparing a sensitised explosive comprising the steps of providing thermally expandable microspheres which, when expanded, are suitable to reduce the density of an explosive and mixing the microspheres with steam to cause thermal expansion of the microspheres and to provide a resulting stream of wet expanded microspheres. The resulting stream of wet expanded microspheres is then introduced into an explosive to provide a sensitised explosive.
