In the process of using Anderson model to superimpose waveform in near field of deep hole bench blasting,in order to eliminate the deviation of the multi-hole pulse sequence and the impulse response,a correcting method of forecasting the effects of vibration was proposed.After constructing the multi-hole pulse sequence in accordance with different intervals,then traversing doing convolution with impulse response,the best fit of the measured waveform was found as the multi-hole pulse sequence under the optimal confidence level.Meanwhile,based on the frequency attenuation law,taking the proximity of the distance from each hole to the measure point and the base hole distance as the parameter for determining the impulse response.With the Matlab forecasting program implanted into the above methods to forecast one blasting vibration,the results show that after correction,the forecast waveform is significantly closer to the measured one and the velocity forecasting deviation drop from 83%-130% to 0%-39%,forecasting accuracy is significantly improved.
