Europe’s largest mining tailings reservoir: displacements
in an industrial tower
Żelazny Most Reservoir is the largest reservoir for copper mining tailings in Europe, owned by KGHM Polska Miedź. It was put into exploitation on February 12, 1977. There are four industrial overflow towers on the site. One of them in 2018, was equipped with vertical 3DSensors to monitor temperatures and horizontal displacements. One of the reasons for DFOS-based monitoring system installation was the construction of the tower’s new floors.

Results of using the DFOS monitoring system
Seven segments of the 3DSensor were delivered on site and installed on the walls of the tower’s individual storeys, along its entire depth. Segments were connected together through the floors to create a continuous sensing line. The measurements were performed during the entire year to analyse the influence of significant temperature changes. This reliable system working in harsh environmental conditions allowed the horizontal displacements of the tower to be measured with extremely high spatial resolution.
