Abstract

The present invention provides a system for the pneumatic extrusion of an emulsion explosive into a borehole. This system comprises a pressurized vessel (2) for holding the emulsion explosive under pressure, a pressurized water source (1) (preferably a vessel for holding water under pressure), an outlet (10) from the emulsion vessel, a water injector (14) connecting the outlet to a delivery hose (16) and a conduit (9) (such as a hydraulic hose) for providing the pressurized water to the water injector.

Claims

AMENDED CLAIMS[received by the International Bureau on 4 December 1997 (04 12 97), original claims 1-10 replaced by amended claims 1-6 (2 pages)]
1. A system for the pneumatic injection of an emulsion explosive into a borehole comprising:
(a) a pressurized emulsion vessel for holding an emulsion explosive under pressure and having an outlet through which the emulsion explosive can be pneumatically discharged,
(b) a water injector connected to the outlet for forming an annular stream of pressurized water around the emulsion explosive,
(c) a pressurized water source for providing pressurized water to the water injector at a pressure at least 10 psi greater than the pressure of the emulsion explosive, and
(d) a delivery hose extending from the water injector for delivering the emulsion explosive from the emulsion vessel nto a borehole, whereby the annular stream of pressurized water lubricates the flow of the emulsion explosive through the delivery hose.
2. A system according to claim 1 wherein the pressurized water source comprises a pressuπzable water vessel and a conduit leading from the water vessel to the water injector.
. A system according to claim 1 wherein the internal diameter of the delivery hose is less than the internal diameters of the outlet and water injector and the delivery hose is connected to the water injector through a coupler that does not disrupt the annular stream of water around the emulsion explosive.
4. A system according to claim 3 wherein a first hose portion is interposed between the water injector and the coupler.
5. A method for the delivery of an emulsion explosive into a borehole comprising: (a) pneumatically extruding the emulsion explosive from a pressurized vessel through an outlet extending from the vessel , (b) providing pressurized water at a pressure at least 10 psi greater than the pressure of the emulsion explosive and as an annular stream around the emulsion explosive as it is extruded from the outlet, and (c) delivering the emulsion explosive from the outlet and into a borehole through a delivery hose, whereby the annular stream of water lubricates the flow of the emulsion explosive through the delivery hose.
6. A method according to claim 5 wherein the diameter of the delivery hose is less than the diameter of the outle .
