DELIVERY SYSTEMS OF EXPLOSIVE MATERIALS AND METHODS RELATED TO IT Russian patent published in 2017 - IPC F42D1/10 C06B21/00 

FIELD: blasting operations.

SUBSTANCE: invention discloses the explosive materials delivery systems with variable density values and methods of changing the explosive materials energy in the blast hole. The blasting energy changing method of the explosive materials in the blast hole includes the following steps: introduce the charging tube into the blast hole; pass the homogenized product, containing the emulsion matrix through the feeding tube; introduce the gas additive proximally to the loading tube outlet with the first constant flow rate; mix the homogenized product with the gas additive proximally to the loading tube outlet with the first flow rate to form the first activated product, having the first density; pump the first activated product into the blast hole; introduce the gas additive proximally to the loading tube outlet with the second constant flow rate; mix the homogenized product with the gas additive proximally to the loading tube outlet with the second flow rate to form the second activated product, having the second density; and pump the second activated product into the blast hole.

EFFECT: invention allows to increase the blasting operations efficiency and to reduce the environmental hazard.
