Abstract

The blast-induced ground vibrations is one of the most important factors which is considered to design blasting patterns in urban excavation. To compare with vibration level of different explosives, peak particle velocity of each explosive was measured. The results are summerized as follows. 1. Among the three kinds of explosives, the largest vibration was obtained from the gelatine dynamite, while the smallest was blasting of ammonium nitrate. 2. The vibration levels of ammonium nitrate and slurry explosive were smaller about 35%, 20% respectively than that of gelatine dynamite.
