Abstract
In this thesis, different empirical models for the prediction of blast induced ground vibrations have been investigated using data previously collected from five different limestone quarries in Egypt. Based on this data, the objectives were to determine the prediction model that best describes the ground vibrations considering the results of previous studies at these quarries. Additionally, the effects of blast design parameters and intact rock properties on the propagation of ground vibrations (i.e. attenuation site constants (k, n)) have been investigated. The results have shown an improvement in the prediction of ground vibrations at some sites. Based on the results, an allowable maximum charge per delay has been suggested based on the measured vibration frequencies and the available vibration standards. It was also found that site constant (k) is more affected by intact rock properties than site constant (n). While the blast design parameters have varying effects on the site constants (k, n).
