description Accurate assessment of seismic source mechanisms is important in seismic monitoring in underground mines. Complexities in seismic source identification, particularly inconsistencies in datasets, may significantly impact the interpretation and accuracy of seismic data analysis. To address this issue, a method for identifying seismic source mechanisms based on the Hudson's Diagram analysis is presented, in which seismic events are classified as blast, slip-type, or crush-type events. Furthermore, in this study, nodal planes and photogrammetry were used to delineate potential slip-planes, which was discovered to be a valuable alternative to map structures where visual mapping is impossible due to the use of shotcrete in-cycle. Finally, the relationship between geological features and seismicity was investigated at the Kanowna Belle mine, where seismicity is described as primarily influenced by geological features. The findings of this study contribute to a better understanding of lithological contact seismic behaviour and the comprehension of seismic monitoring to address the associated seismic hazard. Moreover, it provides tools for early ground support design adjustments and ensures a safe working environment, increasing mine efficiency. Keywords: mine seismicity, moment tensor inversion, source mechanism, geology
