In this paper were presented the results of geodesic measurements which took place in the years 2001 ? 2011 and were carried out by some hard coal mine, which is located at the Upper Silesian Coal Basin in Poland. This mining plant was conducted an exploitation of hard coal in three coal beds named 338/2, 341 and 358/1 which were respectively located at the average depth amounts 600 m, 635 m and 1000 m. In order to observation of the impacts of multi-deposit exploitation conducted at the large depth, the measuring line No 8 was established on the terrain surface above the mining workings. There were carried out the measurements of the points heights and the distances between the neighboring points. On the basis of points subsidence and segments lengths of measuring line, there were calculated the curvatures values caused by this exploitation. These values were compared with the values of curvatures obtained from the numerical modeling. The forecasted values of curvatures were calculated by the use of the Bialek?s formula with the designated values of its parameters. The linear regression equation between the measured and forecasted values of curvatures was determined.
