Disclosed is a system for assisting blasting. The system includes at least one wireless blasting-related device that is deployable or deployed proximate to or within a portion of physical media intended to be blasted as part of a commercial blasting operation. The blasting-related device includes a device-based magnetic induction (MI) signal receiver with a magnetometer configured for through the earth (TTE) MI communication, and the blasting-related device includes a device-based MI signal source with a device-based antenna configured for TTE MI communication. The device-based MI signal source is configured to communicate with a vehicle-based MI signal receiver in a blast support vehicle that includes a set of vehicle-based magnetometers.

Commercial blasting systems

In an embodiment, a photoinitiation apparatus includes: a set of illumination sources or elements configured for outputting optical energy; a body structure having a proximal body structure portion confining a proximal volume of explosive medium, an intermediate body structure portion confining an intermediate volume of explosive medium, and a distal body structure portion confining a distal volume of explosive medium, wherein the proximal volume of explosive medium is optically coupled to portions of the first volume of explosive medium, at least one of the proximal volume of explosive medium and the distal volume of explosive medium is a tertiary explosive medium, and (a) the body structure does not carry a primary explosive composition and does not carry a secondary explosive composition, and/or (b) each of the proximal, intermediate, and distal volumes of explosive media has an initiation sensitivity that is less than cyclotrimethylenetrinitramine (RDX) based explosive compositions.

A process for producing an intermediate emulsion comprising an oxidizer solution, fuel and emulsifier, which process comprises the steps of: (a) mixing in a micromixer an oxidizer solution with a fuel blend comprising a fuel and an emulsifier so as to solubilize a portion of the oxidizer solution in the fuel blend to produce a precursor product; (b) mixing the precursor product obtained in step (a) using a micromixer in one or more successive stages in order to form the intermediate emulsion.

Process for the production of intermediate emulsions for use in emulsion explosives

A method of mining a mineral deposit includes setting a plurality of explosive charges at spaced pre-blast locations in the deposit, wherein at least selected pre-blast locations also carry respective markers that are such that the post-blast location of at least a useful proportion will be detectable after explosion of the charges. After the charges are exploded to fragment the deposit, the post-blast locations of certain of the markers are detected to obtain an indication of the relative positions of selected components of the mineral deposit after the fragmentation of the deposit by the exploding of the charges. Also disclosed is a method utilizing a plurality of markers arranged to emit a detectable signal after blast fragmentation, and detecting the post-blast locations by triangulation techniques employing a plurality of receiver detectors. A further aspect proposes the use of secondary explosive charges as post-blast markers.
