ABSTRACT:
Apparatus for delivering an emulsion explosives composition comprising unpressurized vessel (10) for storing or supplying the explosives composition to pressure chamber (1); sealable chamber inlet (2) for charging chamber (1) with emulsion explosives composition from vessel (10); and chamber outlet (4). Fluid pressure opening (6) applies a discharge pressure to chamber (1) for delivering emulsion explosives composition through outlet (4) to delivery hose (11) for charging blast holes. The apparatus is characterized by pressure chamber (1) having a maximum operating pressure and a volume such that the pressure volume (pV) value of chamber (1) is less than 10 MPaL.
