MINERÍA la mejor puerta de acceso al sector minero MINERÍA / ABRIL 2024 / EDICIÓN 559 47 Abstract A couple of damage events occurred at a mine in Peru. The seismic monitoring system allowed interpreting these situations as a combination of sliding along the orebody and sudden convergence of the workings and/or pits. The maximum vibration estimated using the McGarr (1991) method is 1.04 m/s. Stress modeling shows that the maximum static stress level index (SLI max) varies between 0.4 and 0.9 in the damage zone. The fault depth (dSB) and the duration of the fracturing process (tB) were also estimated using small and medium-sized crushing-type events recorded around the damage zone. The tB varies between 0.01 and 0.03 s. This analysis shows the importance of taking into consideration deformation parameters rather than vibration of the rock mass in the choice or design of an adequate support to mitigate the effect of seismic events.
