Abstract
The procedure involves the mixture of a water based oxidizing product with an oxygen balance greater than 14% consisting of a water solution saturated with oxidizing salts, oxidizing particles in suspension and thickening agents, with a fuel and a gas in a mixer, by means of the formation of an intimate mixture of the oxidizing product and the fuel and the formation of a suspension or emulsion of gas in the mixture. The density of the end explosive product may be varied according to the gas flow and this is controlled before introducing the explosive into the bore. The installation consists of a tank (1) with the oxidizing product, a fuel tank (11), a gas reserve (10), a mixer (5), a pump (3), a dosing device for the fuel (12) with a flow meter (13) and a regulating device of the gas flow (8), and, optionally, a tank (2) with a stabilizer of the gas bubbles, a dosing pump (4) and a flow meter (7).
