ABSTRACT

Ground vibrations arising from excavation with blasting is one of the environmental
problems in mining industry. The prediction of ground vibrations and the realization of
controlled blasting based on this prediction have a great importance in order to
minimize the environmental effects of blasting. The purpose of this study is to analyze
the ground vibrations induced by blasting at Akyol Quarry which selected as a test site
after the determination of the geomechanical properties of the rock mass with a
computer software (AUTODYN 3D) that is able to model three dimensionally. During
the field study, samples were taken from the different regions of the quarry. On these
samples, geomechanical properties of the intact rock samples were determined. Then,
geomechanical properties of the rock mass were estimated. In the numerical modeling
stage, four main numerical models were prepared in the AUTODYN software by using
the data obtained from the field and laboratory studies. The data obtained from these
model runs was compared to the data obtained in the field measurements. As a result of
this comparison, the model that would be used for future studies was selected.
