METHOD FOR BLAST BREAKING OF ROCKS

摘要

FIELD: blasting. ^ SUBSTANCE: breaking is carried out by control of shock wave in space and time due to division of exploded row of explosive charges into zones that consist of identical repeating charges of various form of diametre change, besides length of zone is identified as L=ln, where l is distance between wells, m; n is number of charge variance forms. ^ EFFECT: invention makes it possible to reduce seismic effect at left massif and to improve extent of rocks crushing. ^ 1 tbl
