METHOD FOR BLAST DESTRUCTION OF ANISOTROPIC ROCKS

摘要

A method for blast destruction of anisotropic rocks in pits includes well drilling at block of rocks that is blasted, charging those with explosive substance with placement of initiation means, well stemming, mounting of blast network with installation of means of retardation between the groups of the well charges and blasting. Distances between the charges in a row and between the rows of well charges in any azimuth direction are determined with account of averaged radius of milling cone depending on the length of the well charge.
