ABSTRACT

During the production and service to the humanity of mine resources that are needed
both by industry and construction of new grand buildings and plants that are the basic
news of the modern world parallel to the urbanization and the increase in population, it
is known that, like it has been in the past and will be in the future, works of excavation
by blastings are inevitable. In order to designate the effects of the blastings on
surrounding area, measurements of concussion and air shocks are very important.

This paper presents investigation of the environmental effects of ground vibration
induced by blasting in various quarries depend on Cebeci Quarries Production and
Marketing Cooperative located at Northern Istanbul in Turkey. Within the scope of this
study, scaled distance components have been recorded for all shots at these quarries at
different times. And also, ground vibrations and air blasts produced by these shots have
been recorded by means of different ground vibration monitors. Then, the data pairs of
scaled distance and particle velocity obtained from all records were analysed
statistically. At the end of statistical evaluation of the data pairs, an empirical relation
which gives average line at upper bound 95% prediction line with a good correlation
coefficient was established between peak particle velocity and scaled distance. As a
result of the studies in these quarries in question, some practical approaches 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 the area will be done in a controlled
way.
