Textural properties as micropore surfaces and sorption capacity, chemical and technological analyses of sediments col-lected in the Lazy coal mine landfill (Upper Silesian Coal basin) are presented. The adsorption capacities together with net calorific values (Qid) and total organic carbon (TOC) decreased in the direction of flow while the ash content (Ad) increased. The samples with the highest TOC content have a relatively beneficial Qid and for residual coal particles from coal mining, were comparable with the Qid values of brown coal. The sorption capacity increased with increasing micropore content and correlated with higher levels of TOC. The sorption capacity decreased with distance from the saline water input. These materials play a significant role in the self-cleaning of mine water in-situ.
