Abstract
Palabora experience indicates that seismic hazard and seismic risk change with the caving process but these changes are not always corresponding (Glazer 2012). In this chapter I have used the recorded seismic data to describe the methodology for monitoring the seismic risk. It is interesting to note that presented results based on the analysis of independent of each other parameters (for example energy release of small events, time histories and the Peak Particle Velocity of larger size seismicity) resulted in good agreement. It is important to recognize that some of the parameters are derived from the same seismic source values. In such case the analysis results do not complement each other but simply repeat each other. In this paragraph I do not propose an absolute scale for the seismic risk description. All results are relative and describe the changes in seismic risk over time. From presented in this paragraph analysis it emerges that with the caving process the highest seismic hazard is associated with initiation of the caving progress and then with the cave breaking through. This paragraph describes the methodology that allows for monitoring the changes in the seismic risk. As the seismic risk is directly associated with the stress levels then its estimations should result in more accurate seismic risk approximation.
