The repositories status evaluation
| Class | Filtration RAW (max) | Repository conditions evaluation | Overall technical conditions |
|---|---|---|---|
| 0 | < 2σ | Good | Damages are absent. The all processes are flow under license |
| 1 | ≤ 2σ | Satisfactory | Damages are absent or immaterial |
| 2 | > 2σ | Non satisfactory | Approximately uniform expansion of RAW spot evidence of overall marginal damage of compaction which may be compensated by drainage |
| 3 | ≫ 2σ | Breakdown | Monotonous growth of RAW spot along the direction on the accident’s epicenter evidence of essential damage of repository. It is necessary to build the artificial barrier between repository and important zones near the repository, which are on the way of RAW spot movement. If the RAW spot movement stopping is impossible it should be considered the question of these zones evacuation or alternation of their activity |
