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.

The present invention regards a detonator support device (1) configured for internally supporting an elongated detonator unit (3), the detonator support device (1) exhibits an upper end (5) and a lower end (7) and comprises a first elongated sidewall (9) hingedly coupled to a second elongated sidewall (11) via a hinge member (13), a latching member (15) of the detonator support device (1) is wall (11) in a closed state. A first cord clamping surface (17) of the first elongated sidewall (9) is configured to come in position opposite a second cord clamping surface (19) of the second elongated sidewall (11) in said closed state for engagement with at least one cord member (21). The present invention further regards a method of preparing a detonator support device and a blasting system (100).

A detonation wavefront controller for a linear shaped charge, comprising a first part and a second part. The first part comprises: a detonator holder, and a first aperture having a first width and a shape which is substantially a cyclic polygon, substantially an ellipse or substantially circular. The second part comprises: a second aperture having a second width larger than the first width. With the first part at least partly received within the second part, the first part is moveable relative to the second part to configure the detonation wavefront controller at least between: a first configuration with a first distance between the first aperture and the second aperture, and a second configuration with a second distance between the first aperture and the second aperture, the second distance larger than the first distance.

The present disclosure provides a loading tube to be used in a perforating gun. The loading tube is capable of securely engaging with shaped charges while maintaining the structural integrity and being made by injection molding.

An above ground stemming device is described which includes a body configured, in use, to cover an open end of a blast hole loaded with explosives to surface or to within 300 mm of surface. The body has a void containing a stem of superabsorbent polymer gel therein and it is positioned in use to allow the stem of superabsorbent polymer gel to be in contact with the explosives in the blast hole. The body may include a base and an upper portion extending upwardly from the base. The void may extend through the body to an opening in the base. Alternatively, the void may be encased by the body. The body may be fabricated from a rigid material or from a flexible material capable of being inflated with a fluid.
