Abstract
An explosives container comprising a flexible inner bag within a flexible outer bag, the outer bag comprising a first end and a second end and a booster compartment located on an external surface of the outer bag, adjacent the second end. An explosive composition can be located within the inner bag and, in use, the booster compartment contains an explosive booster and serves to maintain the explosive booster in close contact with the explosives composition. The explosives container further comprises an elongate sheath extending substantially between the first end and the second end of the outer bag and serving to house and protect a detonator cord from damage or dislodgement.
Claims18
An explosives container comprising:
- a puncture resistant flexible outer bag comprising a first end and a second end;
- a flexible inner bay located within the outer bay for containing an explosive;
- an elongate sheath adapted to house a detonator cord, the elongate sheath extending substantially between the first end and the second end of the outer bag;
- and
- a booster compartment, separate from the elongate sheath, adapted to contain an explosive booster, the booster compartment located on an external surface of the outer bag, adjacent the second end.
A method of locating an explosive composition and associated initiating device in a borehole including the steps of:
- placing the explosive composition into a flexible inner bag, the inner bag located within a puncture-resistant flexible outer bag and the outer bag having a first end and a second end and a booster compartment located on an external surface of the outer bag adjacent the second end and an elongate sheath extending substantially between the first end and the second end, the booster compartment being separate from the elongate sheath;
- locating a detonation cord within the elongate sheath;
- placing an explosives booster into the booster compartment;
- and
- lowering the outer bag into the borehole.
