| Abstract: | The excavation of vibration-isolating slot is one of the possible measures to reduce the influence of blasting vibration. Based on the numerical simulation under two-dimension and three-dimension, the effect of the vibration-isolating is studied in the paper. And the influences of the following conditions on the vibration-isolating ratio are analyzed, e.g. (a) different distances between blasting point and vibration-isolating slot, (b)under cut blasting and enlarge excavation, (c) when deep holes is used as a vibration-isolating slot. Some important and enlightening conclusions are made. |
| Keywords: | blasting vibration vibration-isolating slot PPV |
