PROCEDURE FOR DEVELOPMENT OF LAYOUT OF BLAST HOLES PLACEMENT FOR ROCK CAVITY DRIVING Russian patent published in 2011 - IPC E21B44/00 E21D9/00 

FIELD: oil and gas production.

SUBSTANCE: procedure for development of layout of blast holes placement for rock cavity driving consists in: working out computer layout for blast holes placement by means of software for layout of blast holes, determination of at least points of charging and angles of direction of blast holes in coordinate system of layout of blast holes placement for set of blast holes drilled in rock, and determination of location of at least one group of blast holes in layout of blast holes placement and of several blast holes in group of blast holes. The procedure also consists in: determination of at least one master blast hole for at least one group of blast holes in the layout for blast holes placement; determination of at least one dominating parametre for the master blast hole; on base of the dominating parametre of the master blast hole determination of the parametre of at least one another blast hole; and in using the master blast hole, parametres of which can be later corrected, added or deleted and dominating parametres of which can be altered.

EFFECT: fast development of layout of blast holes placement, easy and fact correction of this layout and cut time for design work.
