<jats:title>Abstract</jats:title><jats:p>A total of 56 coal seam samples (from active and closed coal mines) representing USCB Paralic Series, were tested. It was determined that the tested coal has low content of mineral matter (especially in Hruśov Beds) as well as of Ag, As, Ba, Cd, Co, Cr, Cu, Mo, Ni, Rb, Sb, Sn, Sr, V and Zn. Only Mn and Pb content in coal is higher than in coal from other deposits around the world. There are differences in the values of physical and chemical, petrographic and geochemical indices of coal quality, between the northern and the south-western part of the USCB and in the profile of the Paralic Series.</jats:p><jats:p>Thanks to the revealed correlations between the indices of coal quality, significant differences in the role mineral and organic substance play in concentrating some of the trace elements in the tested coal, were determined. Moreover, it was observed that an increase in the rank of coal (expressed with an increase in the value of R</jats:p><jats:p>It was determined that an increase in the value of Roga Index (RI) is accompanied by an increase in P</jats:p>
