The subject invention relates to an apparatus and process for mixing and delivering an explosives composition. The apparatus for use in the process comprises a main conduit which can be gas pressurised, a means for introducing a solid particulate phase to the main conduit for transportation by the gas and a means for introducing an emulsion phase into said main conduit such that turbulence of the gas in the main conduit causes uniform mixing of the solid particulate phase and the emulsion phase.

Apparatus and process for explosives mixing and loading

The application relates to a gas deflecting device for use in the blow loading of emulsion explosives compositions, the gas deflecting device comprising a nozzle which is capable of being removably attached to a blow loading hose, the nozzle comprising at least one vent and at least one vane along its length, the vane being adapted to allow free escape of gas from the nozzle through the vent but inhibit the exit of explosive composition through the vents during blow loading. The application also provides a process for blow loading a blasthole with explosives compositions the process comprising the steps of,
