Abstract:
An explosive assembly for installation in a preformed elongate cavity, the assembly comprising:a length of foldable continuous elongated explosive charge having a first end and a second end; an anchor attachable on or near the first end of the explosive charge so that at least a portion of the first end of the explosive charge remains exposed, the anchor being adapted to be insertable into the preformed cavity without substantial resistance and to resist removal from the cavity; and a tube sized to receive and support the explosive charge behind the anchor, the tube being about the same length as the explosive charge and adapted to support the explosive charge in a non-folded condition while the explosive charge-filled tube is inserted into the cavity; wherein the anchor can be pushed into the preformed cavity with the tube and wherein the tube can be withdrawn from the cavity without withdrawing the anchor or the explosive charge, so that the length of explosive charge is positionable along the length of the preformed cavity.
