Abstract

Different methodologies have been developed and applied in order to understand the phenomenon and behavior of seismicity, especially at a local, regional and global tectonic level. In mining, the analyzes of induced seismicity are limited to deterministic seismic risk assessments, using seismic indicators with which it is expected to understand the behavior of the rock mass when it is performed the mining production process. Because of this, a space - time clustering was used, in order to incorporate the variable time in the analysis of micro - seismicity. This type of clustering allows to define a seismic sequence if each event within this sequence fulfills the condition dST ≤ D, where D is the maximum space - time separation distance and dST = √ (dˆ2 + Cˆ2Tˆ2), which relates the distance (d) and the time (T) between the seismic events related by the value of C. In this study we propose a new methodology to determine the constants C and D, finding the best fit of the Gutenberg - Richter law for the clustered and non-clustered seismicity by the Akaike methodology. With this procedure we will be able to define if the induced seismicity has a mayor space or time influence during the process of rupture of the rock mass
