| Abstract: | The blast vibration waves were measured on the rock and were transferred by FFT. The law of vi- bration wave frequency spectrum changing with the distance was found and the influence characteristics of prop- agation way, charge location and charge mass on the wave frequency spectrum were obtained. Thus, the evi- dences are found for safety design in blasting engineering and in lilitary engineering. |
