allows for concentrating efforts on those points that could
pose a greater risk, ensuring a more detailed and effective
evaluation.
DISCUSSION
Results of the Physical Stability Assessment of Remediated
Mining Structures by CIEMAN in Hualgayoc. The evalu-
ation results show variations in displacement and stability
parameters, reflecting the partial success of the rehabilita-
tion measures applied, while also highlighting areas for
improvement.
Tailings Deposits Stability
The structures exhibit slight displacements in north, east,
and elevation coordinates, with stabilization observed since
2019. However, specific points like H‑20 report low stabil-
ity indices (0.17), indicating that these areas require ongo-
ing monitoring and potential additional intervention to
ensure long-term safety.
Waste Rock Dump Stability
The analysis reveals minimal displacements and progres-
sive stabilization. Nevertheless, low stability index val-
ues (0.05) at critical points suggest that these structures
could approach instability thresholds without preventive
measures.
Long-Term Monitoring
The stabilization observed in several structures since 2019
underscores the effectiveness of the techniques employed.
However, significant variations in certain points emphasize
the need for continuous and more detailed monitoring,
especially in higher-risk zones.
Impact on Communities and Ecosystems
While progress in mitigating environmental risks is evident,
structures with low stability pose potential threats to local
communities and ecosystems. This underscores the impor-
tance of maintaining and enhancing remediation efforts.
CONCLUSIONS
The results of this study highlight that the techniques
implemented by CIEMAN for the rehabilitation of envi-
ronmental liabilities in the Hualgayoc region have been
partially effective, achieving stabilization of several struc-
tures since 2019. However, critical points were identified,
such as certain tailings deposits and waste rock dumps,
which show low stability indices and therefore require con-
stant monitoring and potential additional interventions to
ensure long-term sustainability.
The stabilization observed in various remediated struc-
tures reflects significant progress in mitigating environ-
mental risks and improving safety for local communities.
Nevertheless, these measures must be complemented with
more targeted strategies in high-risk areas to ensure a sus-
tained positive impact on ecosystems and the quality of life
of nearby populations.
This analysis underscores the importance of continu-
ous monitoring systems, which not only allow for the eval-
uation of the effectiveness of interventions but also serve
as a key tool for the early detection of potential instabili-
ties. Additionally, the findings of this research provide valu-
able insights for future remediation initiatives in regions
with similar environmental liabilities, consolidating a
technical approach grounded in sustainability and social
responsibility.
CIEMAN has proven to be a pivotal institution
in addressing mining environmental liabilities in the
Hualgayoc region of Cajamarca. Its comprehensive
approach integrates advanced geotechnical techniques,
revegetation, and long-term monitoring, effectively mitigat-
ing risks associated with legacy mining structures. Through
its commitment to sustainability and safety, CIEMAN has
contributed not only to the environmental recovery of areas
historically impacted by mining but also to the well-being
of local communities and the protection of ecosystems. Its
work serves as a benchmark for the responsible manage-
ment of environmental liabilities in similar contexts, setting
a standard for sustainable and socially responsible practices.
