Abstract
This research was conducted in one of the biggest limestone quarries in Indonesia (Cemindo Quarry) at Lebak, Bayah, Banten, Indonesia. Using signature hole analysis, the vibration was recorded from a series of single hole firing and resulted in delay variation which resulted in the desired vibration prediction value. From a total of 12 data blasts comparing the electronic detonator and non-electronic detonators, analysis data has been made using log scale comparation scale distance and Peak Particle Velocity from every data recording, the result showed that the electronic detonators curve line lies well below the non-electronic detonator curve. This result also indicates that, with distance getting closer to the nearest resident, electronic detonators are still capable of maintaining results below 3 mm/s with an equal quantity of explosives that is used on non-electric blasts. Compared to SHA prediction, every blast of electronic detonators has used the recommendation of SHA analysis which is Inter Hole 53ms and Inter Row 144ms, with predicted value PPV 1.87 mm/s based on nearest distance SHA monitoring 382 m, the actual value was achieved with PPV 1.97 mm/s on similar distance. It could be concluded that the electronic detonator could reduce vibration value by 21.5% compared to non-electric detonators applied in the blasting process in a limestone quarry, in Bayah, Indonesia.
