INVESTIGATION OF ROCKS FOR PROJECTS AT BLASTING IN »KRIŽ« AND »BELSKI DOL« QUARRIES APPLICATION OF THE SHALLOW SEIZMIC REFRACTION METHOD

Abstract

Field investigations of softer and harder dolomite zones, measurements of naturally divided fragments in rock masses and investigations of rock mass by refractional geophysical method in the blasting area of the quarry were carried out. The obtained results provided the basis for selective projects of exploitation and blasting. Safety measures regarding possible damage to adjacent housing estates during blasting were determined (the paper is published in Croatian).
