The Effects the Number of Free Faces on the Level of Blasting Vibration
초록
Blast-vibration tests were carried out to determine the effects of the number of free face on the level of blast vibration. Frequency chatacteristics were also examined by using FFT analysis. To check the effects of the number of free face, charge weight per delay, drilling length, burden and space were applied uniformly and the number of free face was only changed from one to four. The results from tests were checked by regression analysis and K-value.
