The environmental remediation work of this mining area included the aspects of safety and the environment.
In terms of safety, the interventions consisted of sealing all existing underground mine infrastructure, ensuring the protection of mining galleries, as well as the sanitation, protection and sealing of some open excavations, reducing the risk of people and animals falling into them and controlling their entry into these infrastructures.
Regarding the environment, the proposed interventions focused on the cleaning of the external part of the former “fines” dam of the washery to contain the dispersion noted, landscaping and action to contain some scattered heaps next to former mining works, and in the industrial area.
This contract was awarded to MT3 – Engenharia e Obras, Lda for € 500,594.50 and lasted for 145 days.
The investment was co-financed by the Northern Regional Operational Programme under the III Community Support Framework and made it possible to minimize the safety risks related to the galleries, excavations and cuts, which were unprotected, improve the safety at the fines dam and mitigate the impacts on the appearance and landscape of the area.
