摘要： 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.

摘要： The present disclosure describes systems and methods for delivering a primer to an operative depth for initiating an explosion of an explosive material in a blasthole. Systems described herein can include a cap structure providing access into the hole and a separable detonator subassembly that can be deployed to convey a detonator to a priming position. Methods of priming a blasthole can include placing such a system on a blasthole collar and deploying the detonator subassembly in conjunction with loading the blasthole with explosive material.

摘要： 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.

摘要： Disclosed is a magazine apparatus including a first magazine and a second magazine. The first magazine is configured for holding, carrying and dispensing first initiation device components. The second magazine is configured for holding, carrying and dispensing second initiation device components. The first magazine and the second magazine are configured to dispense the first initiation device components and the second initiation device components in a corresponding manner such that a dispensed one of the first initiation device components and a correspondingly dispensed one of the second initiation device components can be assembled together to form a structurally complete, unified initiation device for loading into a borehole.

摘要： The present invention is directed towards an apparatus for providing a nonlabor-intensive process for sealing an opening formed in the ground with a chemically-inflatable bag. The chemically-inflatable bag contains two or more chemical reactants, one of which is a liquid reactant that is initially stored in a liquid-containing device. The liquid-containing device has a removable cap, which upon removal or breakage of the cap permits the liquid reacting agent to contact and react with another reacting agent. The chemical reaction produces carbon dioxide, which expands the chemically-inflatable bag from a collapsed condition to an inflated condition. In the inflated condition, the chemically-inflatable bag fills and protects the integrity of the formed cavity.
