On the detonation velocity measured in a bore hole. Pt. 2. [ANFO and Slurry Explosives]
This study was prepared with the consideration and information obtained after conducting bench cut blasting at the blasting fields. Thus, detonation velocity of a few explosives, especially ANFO and slurry explosives, in a bore-hole is measured by a resistance probe method. It was found that detonation velocity of slurry explosives inside boreholes containing water is lower as compared to that in the boreholes which do not contain water. Also, it was found that detonation velocity of ANFO and slurry explosives in the boreholes is less stable as compared to that of Shin-kiri dynamite. Thus, detonation velocity of Shin-kiri dynamite shows higher values just after priming, then it gradually decreases and attains a constant value. However, in case of ANFO and TNT-slurry explosives, though the detonation velocity shows larger values just after priming and decreases afterward as in the case with Shin-kiri dynamite, the value of detonation velocity is unstable and shows fluctuations. This fluctuation trend is found to be very prominent in case of ANFO explosives.
