Abstract: | A probabilistic relation between seismic activity and the volumeV of extracted deposits in mines is derived $$\Sigma E = C \cdot V^B ,$$ whereC andB are parameters characterizing mining works and the state of rock mass. Assuming that the measure of seismic hazard is the amount of seismic energy released in a given time interval, it is shown how the hazard can be evaluated continuously. The derived relations were tested in selected coal mines in Upper Silesia. |
