    Spatial analyses were carried out to develop a 3D geostatistical model of the spatial variation in the technological parameters of an ash-slags heap connected with the operation of the power utilities located near Świecie (Toruń). Tank A filled with ash-slags was the subject of geostatistical studies. The spatial variation of recoverability e' (defined as the amount of carbon kg recovered from 1 ton of ash- slags), was analyzed. The variation of these parameters in the horizontal and vertical extents of the ash-slags heap was subjected to structural (variographic) analysis using the directional variogram function. The parameters of geostatistical models approximating the directional variogram recoverability e' were the basis for the estimation. Averages Z* and corresponding standard estimation deviations delta/k were estimated for the particular depths of the tank using (3D) ordinary (block) kriging. Thanks to the application of the geostatistical methods to describe the parameters of the waste material (treated as an anthropogenic deposit) databases containing complete valuable input information for a project aimed at utilizing the deposited material were created.
