THE METHOD OF VARIANTS IS APPLIED FOR CALCULATION OF BLASTING PARAM TERS IN CONCRETE MINE Hristo Stoev1, Ilian Djobov2

1University of Mining and Geology “St. Ivan Rilski”, 1700 Sofia; [email protected] 2University of Mining and Geology “St. Ivan Rilski”, 1700 Sofia; [email protected] ABSTRACT. The method of variants is applied for making a blast layout for the conditions of concrete mining projects – quarry for limestone and ore open pit. The analysis of the accomplished results shows that identical values are obtained for the blasting parameters of the both examined objects either regardless the used working method.
