Abstract
The present invention relates to a method and installation for loading boreholes with bulk water-based suspension or watergel type explosives characterized by the sensitization of the product by mixing a non-explosive or low sensitivity suspension matrix with compressed gas (e.g. air) at the end of the delivery hose.
Claims7
A procedure for loading a borehole with a bulk water-based suspension or watergel-type explosive comprising:
- (i) transportation of a water-based matrix suspension to the location for loading, said matrix suspension comprising at least an oxidant salt, a fuel, and a thickener, and (ii) sensitization of the matrix suspension to be explosive during the delivery into the borehole, wherein said procedure comprises:
- a) dosing the matrix suspension into the borehole through a delivery hose,
- b) injecting a gas into the matrix suspension at the end of the delivery hose,
- c) dispersing the gas in the matrix suspension using a mixer located at the end of the delivery hose, and
- d) fixing an explosive density by regulating the flow rates of matrix suspension and gas.
