A two component field mix explosive composition comprising a first solid component comprising ammonium nitrate or mixtures of ammonium nitrate with ammonium perchlorate, and a second liquid component comprising as a first ingredient hydrazine, a second ingredient which is water, alcohol or a mixture thereof, and as a third ingredient ammonium nitrate in an amount no greater than about one-sixth of the total weight of the second component. At the site of use the liquid component is poured into the solid component to form an explosive composition. This composition is detonable in elongate packages as small as one inch in diameter, by use of a blasting cap.

Two component field mix hydrazine base explosive

An explosive cartridge for use in an explosive column train by end to end coupling of a plurality of cartridges. Each cartridge comprises a cylindrical containing shell having an open rear end in which is a closure plug. In the pre-mix condition, the cartridge contains a first solid component of a two part explosive. In field use the closure plug is removed and a liquid second explosive component is poured into the cartridge and the plug reinserted to form a sliding watertight seal with the cartridge. When several of the cartridges are joined in end to end relationship to form the explosive train, the nose end of one cartridge moves the plug of the adjacent forward cartridge inwardly to take up the slump in the explosive composition and maintain the closure plug seal.
