Abstract

The Company "GeoMineral" operates in Astrozub, which exploitation limestone for the needs of quarry and market. In this deposit, drilling is usually 15 [m] deep, where we get a field with 126 drillings of 15 [m] in length is considered. With the distance between the drillings in the row 3.5 [m], with the distance between rows of 3.5 [m] and the drilling diameter 89 [mm]. To perform the blasting, the ANFOKOS explosive with density 0.85 [g/cm3] was taken. For initiation has been taken the Nonel system for initiated of drilling and surface initiation. Based on all the above, it emerges that the distance of uncertainty is up to 184 [m], while the houses are over 500 [m] away from the blasting field. Also and the vibrations result to be 2,508 [mm / s], which proves that the blasts at this site do not have any impact on the surrounding buildings, based on permissible seismic vibration rates. Key words: Nonel system, blasting, drilling, seismic distance, safety distance
