    Abstract: A loading tube is configured to receive one or more shaped charges to form a perforating gun. The loading tube includes a tubular body extending along a longitudinal axis; a cord passage formed into the tubular body; a retention cutoff formed into the tubular body and configured to receive a detonator cord; and a holding element extending into the retention cutoff and being integrally made with a wall of the tubular body, wherein the holding element is configured to hold the detonator cord into the retention cutoff. The cord passage is configured to receive the detonator cord from a bore of the tubular body and to direct the detonator cord outside the bore of the tubular body.

    Abstract: An explosives delivery vehicle for delivering a booster for initiating an explosion of an explosive material in a hole in a floor of a mine pit to an operative depth in the hole. The vehicle comprises a storage assembly for storing a plurality of the boosters, a booster loading assembly for (i) supporting the booster in a delivery position above the hole and (ii) moving the booster downwardly into the hole and inserting the booster at an operative depth in the hole; and a delivery assembly for transporting the booster from the storage assembly to the loading assembly.

    Inventor: Gregory Patching

    Abstract: The invention provides an apparatus and method for preventing surrounding loose rock fragments from falling or collapsing into a blast hole. The apparatus includes a flexible sheet including a pair of spaced apart longitudinally extending side edges and a pair of spaced apart laterally extending end edges. The sheet has a curved form defining a longitudinal passage extending between openings at longitudinally opposite ends, one end of the curved sheet being insertable into the open end of a blast hole whereby the curved sheet closely faces an internal surface of the blast hole and forms a barrier preventing surrounding loose rock fragments from falling or collapsing into the open end of the blast hole. The invention also provides a bench blasting method and a deployment device for deploying the apparatus into a blast hole.

    Abstract: A composite drill gun for use in a wellbore environment can include a detonation housing containing a detonation source, a composite carrier containing one or more encapsulated charges, and a detonation train connecting the detonation source to the encapsulated charges. The detonation source and each individual encapsulated charge are all sealed with respect to the wellbore environment, and thus the carrier need not be sealed with respect to the wellbore environment. The carrier can be made out of composite materials without worry of leaks into the interior of the carrier, as the detonation source and encapsulated charges are all sealed with respect to the wellbore environment. The composite carrier can be easily drilled out of the wellbore after detonation.
