Table 4
Dominant vibration frequency variation at different distances from the blasthole with different natural frequencies.
| | Geomaterial environment | Natural ground frequency (Hz) | Distance from blasthole (m) | The dominant frequency of vibration (Hz) | Distance from blasthole (m) | The dominant frequency of vibration (Hz) |
| | Magnetite | 7.4 | 1 | 170.9 | 160 | 11.86 | | Rhyodacite | 9.5 | 1 | 190.5 | 160 | 14.93 | | Granite | 12.4 | 1 | 226.8 | 160 | 20.96 |
