The mechanical parameters and rock burst tendency for different types of rocks.
| | Specimen type | Compressive strength (MPa) | Elastic modulus (GPa) | Poisson’s ratio | Rock burst tendency WCF |
| | Cubic red sandstone | 82.50 | 37.94 | 0.18 | Strong (21.35) | | Cylindrical red sandstone | 64.67 | 37.90 | 0.18 | Strong (21.13) | | Cubic granite | 136.50 | 47.95 | 0.20 | Strong (25.89) | | Cylindrical granite | 120.24 | 47.90 | 0.20 | Strong (25.50) |
