Abstract

DC60 (20/08/40) This invention provides a system for the extrusion of pneumatic emulsion explosives into The holes are drilled into the ground. This system contains a pressure vessel for Keep explosives The emulsion is under pressure, the compressed water supply (preferably a vessel for keeping the water under pressure), the outlet port from the emulsion container, Water jets, which connect the pin channels It is supplied to the supply and hoses (such as hydraulic hoses) for supplying pressurized water. With such a nozzle The invention provides a system for the extrusion of pneumatic emulsified explosives into The holes are drilled into the ground. This system contains a pressure vessel for Keep explosives The emulsion is under pressure, the compressed water supply (preferably a vessel for keeping the water under pressure), the outlet port from the emulsion container. , Water nozzle which connects the inlet It is supplied to the supply and hoses (such as hydraulic hoses) for supplying pressurized water. With such a nozzle

Claims (6)

1.Systems for pneumatically injecting explosives emulsions into holes into the ground. This includes: (a) A compressed air emulsion container for treating Emulsion explosives are subject to Pressure and has an outlet port where the explosive emulsion can be pneumatically discharged through the outlet port, (b) a water nozzle which is connected to the inlet port. Such output to create a ring-shaped stream of water. Pressurizes the pressure around the explosive emulsion, (c) the pressurized water supply for the preparation of compressed water. Pressure to the said nozzles at The pressure at least 10 psi is higher than the pressure of the said explosive, and (d) the supply hose extending from the nozzle for the delivery of the explosive emulsion from the container. Contains such emulsion Into the borehole into the ground, by an annular stream of compressed water.The pressure is cast Smooth flow of explosives emulsions Through the said transmission pipe 2.The system complying with claim 1, whereby the compressed water supply is composed of Included with water container and hose. Which is taken from the said water container to the said water nozzle 3. The system complies with claim 1, whereby of the aforementioned pipeline having a diameter Inside is smaller than the inside diameter of the outlet port and the said nozzle. And such transmission pipes Connected to such a nozzle Through the joint, which does not destroy the annular stream of water around the explosive emulsion 4. A system corresponding to claim 3 with the first pipe section placed between Water nozzles and such connections 5. Methods for delivering explosive emulsions into holes into the ground. This includes: (a) Extrusion of pneumatic emulsion explosives from the container. Compressed air packing Through the output channel Extended from the container, (b) compressed water arrangement The pressure of at least 10 psi is higher than the pressure of the emulsion explosives and is characterized by a ring-shaped current around the emulsion. The emulsion is extruded out of the outlet port, and (c) the emulsion from the outlet is sent in. It goes into a bore into the ground through a transmission pipe, by an annular stream of compressed water. The pressure casts the explosive flow. Emulsion through such a transmission pipe 6. Method consistent with claim No. 5, where the pipe has a smaller diameter The diameter of the aforementioned outlet
