METHOD FOR EXPLOSION OF ROCKS WITH SOLID INCLUSIONS Russian patent published in 2012 - IPC F42D3/04

Abstract RU 2455613 C1

FIELD: blasting.

SUBSTANCE: method includes drilling vertical main wells, definition of a contour in plan and soil elevations of solid inclusions along the depth of the main wells, drilling additional vertical wells inside the contour of inclusions, charging main and additional wells with explosive charges, with placement of explosive charges in additional wells inside their inclusions and their blasting. Selection of explosive charge parameters for charging additional wells is carried out by the value of product of explosive detonation speed and explosive charge diameter defined from the ratio.

EFFECT: higher efficiency of solid inclusions grinding.
