Sažetak
Construction of the University library was performed within the University campus of Split (Croatia) on a densely populated location. Excavation of a construction pit for the library was carried out by blasting to a maximum depth of 17 m. The nearest building, the Faculty of Electrical and Mechanical Engineering and Shipbuilding, was only 18 m away from the construction site. For determination of a safe seismic magnitude of blasting, trial blasting was performed. The allowed quantity of explosive charge per interval of ignition was estimated by an original method, respecting the world-known norms (ISO 4866, DIN 4150, US BM 8507, and BS 7385) which determine permitted ground velocity oscillations depending on frequency. Based on the results of seismic monitoring on the location of the trial blasting, safe blasting magnitudes and other saftey measures for the execution of excavation works were developed.
