ABSTRACT:
An improved explosive composition and a method for making the composition are disclosed. The explosive composition is prepared by first formulating a gel concentrate that comprises a mixture of a sensitizer, such as hexamethylenetetramine or hexamethylenetetraminemononitrate and an oxidizer, such as ammonium nitrate in water and a gelling agent. Mixtures of sensitizers or mixtures of oxidizers can also be used in our invention. This gelled concentrate can be prepared, stored and later utilized to form the explosive composition by combining from 5 to 60 parts by weight of the gelled concentrate with from 95 to 40 parts by weight of a particulate oxidizer, such as ammonium nitrate or an ammonium nitrate-fuel oil composition. The resulting explosive compositions have increased densities and hence a significantly higher energy per unit volume. If desired, a cross-linking agent can be added to the combination of the gelled concentrate with the particulate oxidizer to improve the stability and water resistance of the thus formed explosive mixture. Other sensitizers can also be added to produce high explosive compositions.
