PURPOSE: A method of construction is relates to a blasting method capable of reducing ground vibration and noise generated upon blasting. CONSTITUTION: An excavation method by blasting comprises performing delay blasting at a particular location, using time series data of vibrations or sounds generated at that time and time series of delay blasting initiation for the delay blasting, predicting time series data of vibrations or sounds of a single blasting at the location, calculating time series of delay blasting initiation, which produces waveforms of delay blasting vibrations or sounds meeting special requirements on the basis of the predicted data of the single blasting obtained in the previous step, and carrying out the subsequent delay blasting in the time series of delay blasting initiation calculated.
