A method for initiation of well explosive charges includes formation of air cavity in the well by a cavity formation device, this is preliminarily filled with air mix enriched with oxygen, installation of intermediate detonator with detonating fuse just in the cavity formation device, filling of explosive substance, formation of stem and application of blast pulse through detonating fuse. Before filling the cavity formation device with air mix saturated with oxygen its walls are fixed with frame. The device is filled with air mix saturated with oxygen at a pressure above 1 atm. |
