 Abstract
 The blasting vibration prediction in the country is mainly carried out by the scaled distance method. But, this method needs a realscale blasting. Recently, the blasting vibration prediction is performed by charging a borehole for a geological investigation and by measuring a blasting vibration as a trial predicting the influence range of a blasting vibration at a stage of preinvestigation before beginning a construction of a tunnel etc.. However, this prediction method is difficult of reflection with the characteristics of real blasting vibration propagation.
An additional method for prediction of blasting vibration is the ‘numerical analysis’ as a prior prediction method. It must be verified for a result of numerical analysis.
In order to overcome these defects occurring between the ‘scaled distance method’ and ‘numerical analysis’, we have adopted the following methods: initially, we developed a new method for the prediction of blasting vibration by means of a superposition modeling data using a single hole blasting waveform. Then, the delay interval theory had been verified with a compatible superposition model. Next, the relationship between the size of blasting vibration and frequency was defined using the superposition modeling data obtained from a single borehole waveform. Finally, the change in magnitude of blasting vibrations was clarified by increasing the number of holes and delay intervals.
Langefors' 2.5T criterion is discussed instead of 8ms, 17ms, 25ms suggested by scholars as intervals which a vibration does not affect an adjacent hole. In case of less than 8ms, the frequency range of 1~200Hz was contained under the section between 0.5 and 1T. Furthermore, the lowest vibration velocity was observed by a destructive interference each other at 60Hz and the higher vibration velocity than 60Hz was also observed in other frequency range. In case of 17ms, both the constructive and destructive interferences were appeared in the frequency range of 1~ 150Hz and the interference of an adjacent blasting was disappeared at approximately over 150Hz.
On the other hand, both the constructive and destructive interferences in case of 25ms were appeared the frequency range of 1~100Hz, and the interference was disappeared over 100Hz.
In order to verify the reliability of the superposition modeling, the delay interval induced from 29m on the same blasting is applied to one of 69m. The result was showed a similar waveform. It means that the compatibility of the superposition modeling through single hole waveform was verified.
Moreover, the variation of a vibration velocity with increasing the number of holes is investigated through the superposition modeling. Then, the dominant frequency of a single hole waveform and the variation of vibration in accordance with delay intervals was compared and analyzed with Langefors' delay interval definition.
Modeling is performed that the delay intervals were increasing from 1ms to 80ms with 1ms interval and the number of holes from 2 to 15. The analyzed result was good agreement with Langefors' delay interval definition. In addition, a vibration velocity increases with increasing the number of holes, and then converges at constant the number of holes.
The analyzed result on data, which shows the scaled distance equation using the measured data from the field and the highest or the lowest vibration velocity of the peak vibration velocities produced by a superposition modeling of a single hole waveform, was compared and analyzed. By the results, the measured data in 95% reliance almost corresponds with the superposition modeling data of 1ms; moreover, the measured data in 50% reliance nearly corresponds with one of 2T. The superposition modeling data of 1T also shows an appearance being across between 50% and 95% reliance. It suggests that the measured data occurs in the delay interval range of 1ms, 1T, 1.5T and 2T, appearing at the superposition modeling. However, the superposition modeling data of 0.5T is different one from the measured data. The fact, which the analyzed result by superposition modeling data of 0.5T is not accordance with the measured data means that the delay interval of a real blasting in the field does not occur in the range of 0.5T.
It is identified that the prediction equation of a blasting vibration by means of the superposition modeling done by a single hole waveform is almost similar with the scaled distance equation by means of data obtained from a real blasting. Therefore, it is estimated that after obtaining a single hole waveform by a single hole blasting in a blasting area planned, and superposition modeling this waveform, the suitability on the method predicting the blasting vibration propagation equation for a site blasting is verified.
