Ensure the mechanical stability of a tailings dump

Ensure the mechanical stability of a tailings dump

Deadline: Monday 8th June 2020.

EXPANDE invites you to prequalify for a new challenge of Antofagasta Minerals' Antucoya Mine “Ensuring the mechanical stability of a gravel dump”.

Due to the presence of a high quantity of fines and humidity in the reclaimed tailings, the material has a low resistance for the transit of equipment and installation of the infrastructure, therefore, an activity has been incorporated that ensures the load capacity in specific areas of the tailings dump. This method consists of removing material deposited in the dump, to replace it with sterile material of higher granulometry and without moisture, along the tracks of the equipment and infrastructure that are re-installed in each transfer (shifting). This civil road construction activity requires a high amount of resources and time for its execution.

To participate, follow this link: register and submit your proposal before Monday 8th June.
