movement, and stability index, the initial and final measure-
ment points corresponding to April 2006 and December
2022 are considered.
Table 2 shows that the total displacement variation
between 2006 and 2022 ranges from 6.9 cm to 7.5 cm. The
orientation of this ground movement varies between 23.46°
and 86.63°. Additionally, the recorded stability index fluc-
tuates between 0.036 and 0.042.
The stability values are very close to each other and are
below 0.05, indicating that all these points have relatively
low stability. While they are not in a critical range, these
points could be at risk of experiencing further instability.
The other tailings and waste dumps were also subject to
analysis, which allowed us to obtain data indicating overall
stability in these areas. These results suggest that, in com-
parison, the structures are in a more balanced state and do
not show signs of significant instability.
The analyzed structures exhibit similar behavior in
terms of stability, so the decision has been made to focus
the analysis on the most critical ones. This approach
