ABSTRACT

Ground vibrations and air blasts are integral part of rock blasting and unavoidable.
Depending on level of the stresses produced from wave motion, they cause damage to buildings
structures in the nearby residents by causing dynamic stresses that exceed the strength of
building material or rock material. So ground vibration effects induced by blasting on building
structures and human beings need to be predicted, monitored and controlled. In other words,
prediction of ground vibration components is of great importance for the minimization of the
environmental complaints.
In this study that realized at Kayabasi Limestone Quarry on the basis of a Research
Project, ground vibrations induced by blasting were measured in order to describe environmental
problems. Together with surface installation of quarry, there is also a village around test site.
Because of the existence of residential area, cautious blasting was necessary. During the
full-scale experemential study, while the parameters of scaled distance (charge quantity per
delay and the distance between the shot and the station) were recorded carefully, the ground
vibration components were measured by means of vibration monitor (Instantel Minimate Plus
Model) for every the event. Then, the data pairs of scaled distance and particle velocity were
analyzed. At the end of evaluations, an empirical relationship with good correlation was
established between peak particle velocity and scale distance for this site.
