Europe’s largest tailings pond demanded deep ShapeArray monitoring

With a development capacity of over 1.1 billion cubic metres, that accepts 80,000 tonnes of tailings each day, the Żelazny Most Reservoir plays an essential role in Poland’s economic activity. When the engineers at the Żelazny Most Reservoir began to suspect that the ground beneath Europe’s largest copper tailings pond might be moving, they needed new monitoring solutions.

ShapeArray enabled monitoring at an unprecedented depth, which provided Żelazny Most Reservoir’s owners, KGHM Polska Miedz, a way to monitor slope stability and deformation in the dam foundation.

ShapeArray is part of a monitoring program at the reservoir to accommodate the increased tailings produced by Poland’s copper mine.
