| Abstract: | Vibration is one of the most damaging effects of blasting. To avoid the effect in open mining on nearby civilian houses, according to the specific condition of mines, a series of in - situ experiments were made with the technique of microsecond delay and hole - by - hole firing. The results show that this technique can be used to decrease the damage effects of blasting vibration effectively in open mines. |

| Keywords: | Blasting vibration Open pit Hole - by - hole microsecond delay firing |
