A method for producing a warhead with directed blasting action involves the step of making an outer casing and arranging therein a charge with a cavity situated at the front end of the charge. An insert whose shape corresponds to the shape of the cavity is arranged on the surface of the charge. The method furthermore involves the step of depositing a material on the insert in an additive manufacturing process. A warhead manufactured according to the method includes an outer casing, a charge with a cavity situated at the front end of the charge, and an insert. A material is deposited on the insert.

Liners (150), fittings (11-22), and spacers (23-25) are provided to assemble the jet (170) units, which work as explosives (110) and detonators (120) to form stand-off distance and air-deck (140) space. The liners (150) release jets (170) and the fittings (11-22) and spacers (23-25) are designed to attach the liner (150) firmly to the explosives (110), inducing the cavity effect. The objective of the present invention is to provide a blasting method using a jet (170) unit to overcome the limits of sympathetic detonation, applying a mechanism that is ideal according to the analysis of observations in blast-hole (100) blasting. The application of jet (170) units for jet (170) detonation in blast-hole (100) blasting overcomes the performance limits of explosives (110) manufacturing and the conceptual limits of detonators (120) functionalities and improves the channel effect, dead pressing, loss of power, and stopping of detonation etc. Particularly, the application of controlled blasting and air-decking can be carried out without restriction while maintaining the safety of the slurry or emulsion explosives (110).

A compact energetic-breaching apparatus is provided. The compact energetic-breaching apparatus is configured to receive energetic materials for use in energetic breaching. The compact energetic-breaching apparatus may comprise a housing body with a receptacle to receive energetic materials. The compact energetic-breaching apparatus may further comprise a tamping material. The compact energetic-breaching apparatus may further comprise a metal liner which collapses upon detonation to form a cutting jet.

A firing stand (30) for mounting a plurality of shaped charges. The firing stand (30) can be configured by a user between a transport configuration in which shaped charges are stored for transport, and at least a first firing configuration from which shaped charges can be deployed. Inter-connected rotating panels (31) may be used to provide user configurability to the firing stand (30), with shaped charges optionally being mounted in panel apertures (36). The firing stand provides for rapid and configurable deployment of multiple shaped charges.

The invention relates to a process for forming a pre-defined recess in a cured or cast explosive composition comprising the steps of: i) providing a female mould, ii) providing a male former, and locating said male former proximate to the female mould to create a gap between said male former and female mould, iii) forming an admixture of a curable/castable explosive composition, charging the gap with the admixture of explosive composition, causing the cure or cast of said curable/castable explosive composition, removing the male former to furnish a cured or cast explosive composition with a pre-defined recess.
