Abstract: An emulsion explosive composition is especially suited to being pneumatically loaded into a blasthole. The emulsion explosive composition includes a base emulsion phase which has a continuous fuel phase and a discontinuous oxidiser phase, wherein the viscosity of the base emulsion phase is less than 2000 cP (Brookfleld viscosity #4 spindle at 50 rpm) at 25°C.

Abstract: An apparatus and process for the production of any emulsion explosives composition and loading it into a blast hole (7) which utilize a loading conduit (4) having a shear inducing means (5) and a liquid lubrication source (b) adapted to provide a layer of liquid lubricant between the conduit (4) and emulsion explosives composition being pumped through the loading conduit (4). The conduit also comprises a mixing means (8) located at or near the outlet of the conduit (4), the mixing means (8) incorporates at least some of the liquid layer into the emulsion explosives composition.
