After a description of the geology of the area a geostatistical study based on 2968 core samples of 193 drill holes is presented. The coal samples present a symmetric frequency distribution. Experimental variograms representing three main directions - strike plunge, cross-dip and downdip directions - are calculated and a simple spherical-type model is fitted to the variograms. The model parameters are validated. Storages capacities for buffering and homogenisation are estimated taking into account of longer operation standstill of the Çöllolar mine and daily fluctuations of quality parameters. In order to estimate the storage capacity of stockpile and number of stacking layers, block variance of varies size blocks are calculated utilising F chart. Finally, numbers and dimensions of prismatic type linear stockpile bunkers are determined.enAfşin-Elbistangeostatisticscoalstock pileblock varianceArticle
