This paper presents the results of ground vibration measurements and environmental issues occurred on tunnel blasting activities during KavacД±k-Beykoz waste water tunnel construction under a residential area in Istanbul, Turkey. Within the scope of the study, the blasting pattern of tunnel was engineered by using Tunnel 2000 design software. 5 events in 5 shots at S2 shaft tunnels, , 6 events in 6 shots at S4 shaft tunnels, , 32 events in 32 shots at S6-shaft tunnels and, 7 events in 7 shots at S7 shaft tunnels w...

In this study, the vibration and air shock measurement results are given in order to evaluate the environmental results of excavation works with explosions executed in the agrega quarry by Д°lkdal Mining Industry Ltd. Corp. which is working in the borders of Kemerburgaz region of Ey\"up county in Д°stanbul city on producing agrega. The blasting pattern, explosive material charge parameters and vibration measurement results of each blastings are recorded. In the research, the frequency and particle velocity quantit...
