In this paper the results of levelling measurements in the city of Inowrocław were presented. Height changes within the last 10 years are relatively small (within several-mm) and their distribution indicates certain regularities. They depend on the characteristics and the location of the observed vertical displacements. The picture of the movements is complex - apart from subsidence - uplift was recorded. For the interpretation of the results it was necessary to refer to the situation in terms of condition related to mining and geology of earlier distributions of deformations (continuous and discontinuous). Jet, the modelling of selected temporary subsidence troughs was done (during the time when the mining was still carried out). This modelling meant the determination of the parameters of the functions describing selected distributions of temporary subsidence. Such an approach made it possible to determine zones of anomalies (where the values of subsidence showed the deviation from the established trend), which turned out to be zones of height changes, which were observed in those times. Presented results of the papers can give the view of possible behaviour of the salt rock mass after the exploitation of deposit is over, in similar conditions related to mine and its geology, using Inowrocław as an example.
