Abstract

The invention provides a free-flowing particulate explosive comprising 20 % to 90 % by mass of a particulate solid oxidiser, and 10 % to 80 % by mass, of a water-resisting emulsion, said emulsion having non-stick coating properties when at least partially coating the particles of said oxidiser thereby rendering said particles free-flowing.
