THE ANALYSIS OF BLAST-INDUCED GROUND VIBRATIONS FOR DIFFERENT ROCK UNITS

Abstract

This paper presents the analysis of ground vibration parameters induced by blasting excavations realized at different sites located close to the residential areas. Within the scope of this study, in order to predict peak particle velocity and determine the slope of the attenuation curve for all sites and rock units, ground vibration components were measured for all blast events over a long period. During the study, while the parameters of scaled distance were recorded carefully, the ground vibration components were measured by suitable monitors for the all blast events of all blasting sites. At the end of evaluation of the data pairs, empirical relations, which gives average line at 95% confidence level and upper bound 95% prediction line with good correlation coefficients were established and suggested for each site and rock unit. As a result of the studies in different rock units in question, some practical charts are created in order to minimize the psychological effects of the shots and make the authorities of shots job easier and make sure that the shots in different rock units will be done in a controlled way.
