| Abstract: | By means of Instantel Monitor the vibration velocity monitoring data are got when medium length or deep hole blasting takes place where hard rock tunneling advances rectangularly,and based on the data the PPV formula of blasting damage dimension is gained which is suitable to the real tunneling situation.The biggest safe charging weight of single section is contra-calculated by the mathematical statistics method.The charging weight is put into engineering practice,and good result is achieved. |

| Keywords: | tunnel with right-angle round medium-length or deep hole blasting vibration velocity ppv regression |
