Summary unavailable due to content policy. See the patent text for details.

Claim 1

1 . 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. 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.
