爆発に関する研究(第2報) ANFOによる爆破(1)

Abstract

Using the ANFO blasting agents of the prilled AN which had the properties describedin our previous report, we tried the practical blasting by the bench cut method at the damsite consisted of quartz trachyte at Kasabori, Niigata Prefecture, Japan. We used approxi-mately 15kg of the ANFO blasting agents for each bore hole.Through the practical blasting, we came to the conclusions that the ANFO blastingagents were inferior to ammonium perchlorate explosives (Carlit) in view of the blastingforce, and that the ANFO blasting agents were usable and effective only when used in thedry holes.
