The process for sensitizing in situ aqueous explosives before charging the mine holes comprises the formation of an emulsion of dispersion gas-in-liquid from a low sensitivity or non explosive matrix product which consists of a liquid mixture in solution, emulsion or suspension of oxidant in fuel, and a gas. The density of the final explosive product can be varied as a function of the gas flow rate and can be controlled before introducing it into the hole. The installation comprises a tank (1) with the matrix product, a gas reserve (10), a mixture (5), a pump (3), and a gas flow rate regulating device (8) and optionally a tank (2) with a gas bubble stabilizing agent, a dosing pump (4) and a flow meter (7).
