    The Bełchatów lignite deposit is located in the central part of Poland, in the tectonic Kleszczów graben. The theme of researches has been statistical analysis of local, horizontal variability selected depositional parameters from small area (8x8 m), located in the central part of the Bełchatów area. In the investigations was used statistical methods like descriptive statistics, distribution analysis, correlation and regression analysis. Results of the descriptive statistics of the main lignite qualitative parameters beyond little lower capacity of the total sulfur content parameter are contained in to limits which are published by the Bełchatów mine. The researches shows the statistical significance local, horizontal variability of ash and sulfur contents. Simple and multiple linear correlation and regression analysis acknowledge known from literature relations between moisture, ash content and calorific value.
