INFLUENCE OF SEISMIC BLASTING EFFECT ON NEIGHBOURING STRUCTURES (A COMPARATIVE ANALYSIS)

Abstract

The article gives a comparative analysis of allowed explosive quantities at blasting in the limestone quarry »Špica« (Ljubeščica, Hrvatsko Zagorje) executed were precise measurings after mass blasting. The measurings were performed at two observation spots, with three-component geophones and a comparative analysis, considering the criteria in the world are described (the paper is published in Croatian).
