| Abstract: | This paper extracts peak value of blasting pressure which obtained by stored testing and measuring devices. The data are processed by Kaiser-window and translated baseline after frequency domain analysis. It is available to sieve natural frequency of sensor and high frequency noise. Processed peak value of abnormal blast wave is same as the distance of normal. It's success to obtain the peak value of abnormal data. |
