COMPOSITION OF EXPLOSIVE AND METHOD OF DELIVERY TO WELL Russian patent published in 2020 - IPC C06B31/28 C06B23/00 C06B47/14 

Abstract RU 2722781 C2

FIELD: drilling of wells.

SUBSTANCE: invention relates to composition of explosive suitable for use on weak and moist soils. Composition of explosive contains an explosive, which includes an oxidative component in water phase of emulsion of "water in oil" or water-suspension gel and a bulky substance in amount of 1 to 50 wt %, containing discrete particles of a solid combustible substance. Combustible substance dissolves in water but is insoluble in the composition of explosives. Composition contains from 50 to 99 wt % of explosive. Also disclosed is a method of supplying an explosive composition to a well and a method of reducing emission of flue gases by using said composition of explosives.

EFFECT: solution is a new composition of an explosive suitable for use on weak and humid soils.
