Abstract
The waveform at the blasting pattern using k13 delay electronic detonator depends on the interference of adjacent delay time according to the degree of distance and frequency. The degree of interference affects the size of blasting vibration at a measuring point. This study analyzed the cooperating change characteristics of MS delay blasting separately detonated at intervals of 40m and presented through frequency the delay time design method that is able to reduce the cooperation of blasting vibration at the MS delay blasting.
