Table 3
Comparison of the importance of each index of rock fracture ability classification.
| | Evaluation index | Rock mass density | Tensile strength | Wave impedance of rock | Intactness index of rock mass |
| | Rock mass density | 1 | 1/5 | 1/4 | 1/3 | | Tensile strength | 5 | 1 | 2 | 3 | | Wave impedance of rock | 4 | 1/2 | 1 | 2 | | Intactness index of rock mass | 3 | 1/3 | 1/2 | 1 |
