Time ratios of each stage in the rock burst process of different specimens.
| | Specimen type | The quiet period duration (s) | Percentage of the quiet period duration (%) | Duration from violent band stage to burst instability stage (s) | Percentage of duration from violent band stage to burst instability stage (%) |
| | R3-5 | 0∼621 | 82.25 | 721∼746 | 3.18 | | R4-5 | 0∼201 | 74.44 | 252∼265 | 4.81 | | G3-1 | 0∼734 | 85.68 | 815∼835 | 2.35 | | G4-9 | 0∼304 | 76.77 | 354∼376 | 3.03 |
