THE REVISION OF THE SUPPOSED EFFICIENCY OF BORE HOLE EXPLOSIVE CHARGES WITH DIFFERENT CROSS-SECTIONAL SHAPES IN THE FIELD CONDITIONS OF A GRANITE QUARRY

Abstract

This article is devoted to the problems of development mineral resources that are formed by strong
rocks using deep-hole charges of different crosssectional shape to regulate the intensity of grinding
and achieve rock mass quality output .
The article presents the results of mathematic
simulation, the results of experimental industrial researches. The results are analyzed, on the basis of
them conclusions are formulated and the efficiency
of the described technology is proved.
