It has been shown thai the analysed process can be assigned 10 the group of stochastic processes. A model (IO) has been determined as the formal definition of the discussed problem, whereas two algorithmic procedures appear to be the real solution. Utility aspect of the paper comprises the modelling of the formation process of actual dislocations. Estimated values of one-stage prognosis are shown in table I and in Fig. 4. Model quality indicator - error distribution - appears to be the confirmation that a quantitative description is adequate to the survey results. It has been shown from the point of view of descriptive statistics, using correlation coefficient, that the results of the dislocations survey of the field points - significantly distant included - are highly correlated.}, type={Article}, title={Estimation of the missing results of the surveys concerning a non-stationary post-mining dislocations field}, URL={http://journals.pan.pl/Content/121440/PDF-MASTER/5_GK_TOM_LII_ZESZYT_3_2003_Piwowarski_Szacowanie.pdf}, }
