FIELD: mining industry.
SUBSTANCE: group of inventions is intended for being used in the mining industry in the development of quarries and pits for destruction of rocks and ores. An explosive delivery system contains the first tank made with the possibility of storage of an emulsion matrix containing a continuous fuel phase and an intermittent oxidizing component phase; the second tank made with the possibility of storage of a homogenizing additive; the first homogenizer made with the possibility of homogenization of the emulsion matrix and the homogenizing additive with the formation of the first homogenized product, thereby reducing a size of drops of the oxidizing component phase in the fuel phase. The first homogenizer is functionally connected to the first tank and the second tank. The first mixer is made with the possibility of mixing of the emulsion matrix and the homogenizing additive. The first mixer is functionally connected to the first tank, the second tank, and the first homogenizer. The first mixer is located upstream from the first homogenizer. A supplying pipeline is functionally connected to the first homogenizer and is made with the possibility of supply of the homogenized product to a borehole. The emulsion matrix containing the continuous fuel phase and the intermittent oxidizing component phase is supplied. The homogenizing additive is mixed with the emulsion matrix to form a mixed product, the mixed product is homogenized to form a homogenized product, thereby reducing a size of drops of the oxidizing component phase in the fuel phase. The homogenized product is activated, and the activated product is supplied to the borehole.
EFFECT: emulsion matrix is provided, suitable for being used both in surface and in underground applications, having a shelf life compared to existing surface emulsion matrices, i.e., a shelf life compared to emulsion matrices not containing or essentially not containing a homogenizing additive; increase in viscosity, when applying a shear force to the emulsion matrix and/or retention of the emulsion matrix in a rising borehole is provided without significant reduction in “sleeping time” of the emulsion matrix.
