METHOD OF EXPLOSIVE BREAKING OF BROKEN-UP ROCK MASS AT BREAKING ONTO BASSET |
摘要 |
FIELD: breaking of broken-up rocks of any types. SUBSTANCE: the method consists in drilling-up of rows of well blastholes in area of the rock mass to be broken in a strictly definite order: the distance between the rows of blast-holes (wells) should be equal to W (not more); the distance between the blast-holes (wells) in rows should be equal to r<SB>r</SB> (not more), and their breaking in turn, producing the design contour of the broken-up mass. The values of W and r<SB>r</SB> are determined depending on the strength characteristics of the broken-up mass and powder of the explosive used. EFFECT: enhanced efficiency. 1 dwg
