3-D NUMERICAL MODELLING OF GROUND VIBRATION WAVES INDUCED BY BLASTING AT A QUARY
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.
