Abstract
This study is to evaluate an irregular drill-hole depth having an effect on the blast vibration. The relationship between a peak particle velocity and a cube root scaled distance with respect to three drill-hole depths with 2.1m, 2.3m and 2.4m are compared and analyzed using a numerical regression analysis. According to the results, the deeper a drill-hole depth is the larger a peak particle velocity is. It is suggested that a drill-hole depth is proportional to a peak particle velocity at the same scaled distance. Therefore, a regular drill-hole should be carried out in order that the blast vibration velocity of a fixed range under a allowable vibration velocity is maintained.
