摘要:
The present invention relates to a blasting method which comprises conducting a delay blast at a particular location; predicting time series data of a waveform of ground vibration or noise at a remote location to be generated by a hypothetical single-hole blast at the particular location using at least one of previous time series data of a waveform of ground vibration or noise generated by said delay blast and actually monitored at the remote location, and the corresponding previous actually applied initiation time series of said delay blast; computing a delay blasting initiation time series for a delay blasting, which provides a waveform of ground vibration or noise satisfying specific conditions, based on the above-predicted time series data of a single-hole blast; and carrying out a subsequent delay blast according to the computed delay blasting initiation time series.
