METHOD FOR IMPLEMENTATION OF THE OUTPUT CHARGING TECHNOLOGY IN THE FORM OF THE BLAST HOLE OR THE BORED HOLE DURING THE BLASTING OPERATIONS (VERSIONS) Russian patent published in 2017 - IPC F42D1/08 F42D3/04 

FIELD: blasting.

SUBSTANCE: method includes the installation into the functional cavity (FC) 2 of detonator 3 output 1 with conductors 4 of the initiating impulse, blasting charge 5 and stems as a spacing breech (SB) 6 of V-type, including a sleeve 7 with sliding structures 8 and 9 and placed in its cavity element 10 with wedge surfaces 11 and 12, cooperating with facing to it surfaces 13 and 14 of the structures 8 and 9 of the sleeve 7. Before SB 6 installing in the channels 15 and 16, formed in the constructive elements SB 6, place the conductors 4 of the initiating impulse with their ends taking outside FC 2 of the output 1. After SB 6 entering the mouth 17 of output 1 perform its ducting along the output 1 by means of the tamping bar 18 to the specified distance and fix SB 6 in this position. To fix SB 6 in the specified position provide the structures 8 and 9 wedging of the sleeve 7 by effecting on the sleeve end 7. For this purpose, the tamping bar 18, whereby providing the mentioned effects in the direction of the installed blasting charge 5, providing displacement of the sleeve 7 relative to the element 10 with wedge surfaces 11 and 12. In the process of SB 6 ducting operation use the constructively-technological measuring tool 19, that is fixed in the axial direction relative to the element 10 with wedge surfaces 11 and 12 of SB 6. The distance of SB 6 specified installation from the mouth 17 of output 1 register on the control labels or constructive-technological fixing protuberance 20, formed at the measuring tool 19. In the process of structures 8 and 9 wedging of the sleeve 7 perform the element 10 retaining in axial member 10 with wedge surfaces 11 and 12 at the installation site SB 6. For that purpose the fixation of measuring tool 19 relative to the stationary base structure is carried out.

EFFECT: invention enables to provide fixation of stem with complete exception of its contact with explosive materials.
