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.
