Explosive formulations of mixture of carbon dioxide and a reducing agent and methods of using same
11479517 · 2022-10-25 ·

The disclosure relates to embodiments of an explosive formulation comprising a detonable mixture of an oxidizing agent such as carbon dioxide, and a material that decomposes the oxidizing agent exothermically (a reducing agent), and additives that increase the mixture's shock sensitivity. The formulations may be used in a method to produce diamonds or nano oxides or in other applications that use traditional explosives such as, but not limited to: ammonium nitrate and fuel oil combinations (ANFO), watergel explosives, emulsion explosives and RDX.

Method and apparatus for preventing rock fragments from entering or collapsing into a blast hole
11598620 · 2023-03-07 · ·

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.

11473891 · 2022-10-18 · ·

The present disclosure relates to a detonation connector having an electric wire mounting structure, the detonation connector includes: an electrically conductive wire-connecting bracket member having a plurality of electric wire mounting gloves to which a leg line or a leading line is mounted; a lower casing member at which the wire-connecting bracket member is positioned; and an upper casing member covering the lower casing member, wherein the lower casing member may be provided with an opening through which a leg line passes, and the lower casing member is provided with a leg line mounting part therein. Accordingly, a stable connection state in the connector is maintained by fixing a double coated electric wire or a single coated electric wire in a state of being mounted to an opening of the detonation connector and the connection stability and the connection reliability of the leg line and the leading line are secured.

Blast patterns

Techniques for improving a blast pattern at a mining site include conducting an initial blast and recording the initial blast as a high speed optical video. The high speed optical video, and the blast pattern used in the initial blast are sent as inputs to a machine learning model, which correlates one or more characteristics of the region being blasted with measurements associated with characteristics of the region being blasted obtained from the high speed optical video. The machine learning model can then determine an improved blast pattern based on the correlation made. This improved blast pattern can be displayed on a user computing device, or transmitted to a drilling system to automatically drill the improved blast pattern for subsequent blasts.
