Abstract

A low density explosive is provided which is comprised of a mixture of particles of an oxidizer salt, such as ammonium nitrate prills, an emulsion explosive matrix, and particles of a low density material such as perlite or foamed polystyrene. The explosives of the present invention provide a lower density material than comparable ANFO or Heavy ANFO type explosives.
