In this article was designated a relation of average values of measured curvatures of mining terrain with their forecasted values. These values were calculated by the use of the Bialek?s formula with the values of its parameters determined from the geodesic measurements results. The average graphs of measured curvatures were obtained on the base of average values of terrain subsidence caused by multi-seams exploitation of hard coal at the great depth. An exploitation was conducted by the use of longwall system, in the 338/2, 341 and 358/1 coal beds. The subsidence of terrain surface were observed within 10 years, at the measuring points of 8th observational line which was stabilized parallel to the run of the B ? 2 longwall in the 338/2 coal bed. The average graphs of measured subsidence were determined using the least squares method. The smoothed splines were applied as an approximating function. Thanks to average courses of observed curvatures, it?s possible a making of the model verification which was used to the calculation of curvatures forecasted graphs.
