Abstract

The use of an explosive’s energy during blasting includes undesired eff ects on the environment. The seismic infl uence of a blast, as a major undesired eff ect, is determined by many national standards, recommendations and calculations where the main parameter is ground oscillation velocity at the field measurement location. There are a few approaches and methods for calculation of expected ground oscillation velocities according to charge weight per delay and the distance from the blast to the point of interest. Utilizations of these methods and formulas do not provide satisfactory results, thus the measured values on diverse distance from the blast fi eld more or less diff er from values given by previous calculations. Since blasting works are executed in diverse geological conditions, the aim of this research is the development of
a practical and reliable approach which will give a diff erent model for each construction site where blasting works have been or will be executed. The approach is based on a greater number of measuring points in line from the blast fi eld at predetermined distances. This new approach has been compared with other generally used methods and formulas through the use of measurements taken during research along with measurements from several previously executed projects. The results confi rmed that the suggested model gives more accurate values.
