TY - JOUR N2 - The open-cast nature of deposit exploitation means that apart from the extraction of the main mineral, rocks are also found in its vicinity. Their nature, raw material quality and geological and mining conditions allow them to be used in various branches of the economy. Hence, it seems that more attention should now be given to these rocks. However, the long-term, open-cast mining operations involving Bełchatów lignite ultimately necessitated basic, raw-material-related research on the deposits accompanying the lignite as the main mineral. The presented work shows the state of the recognition of rocks lying in the Mesozoic–Neogene contact zone in the Bełchatów lignite deposit as well as their petrographic nature and possible directions of their use. Attention was drawn to the lithological diversity of the studied rocks and diagenetic processes that contributed to the impact on their physical and mechanical characteristics. Based on the analysis of the literature, the current state of utilization and development as well as the balance of accompanying rock resources in the Bełchatów lignite deposit are presented. Today, it would seem very important from various economic points of view for utilization and management of the aforementioned rocks encountered as open-cast lignite mining to take place. Natural resources are protected where the area mined is kept in check, and there is economic significance to any increasing in the supply of minerals, or materials made from them. The level of profitability for economic entities that exploit lignite deposits may obviously be raised in this way, and environmental goals can also be served if some of what is extracted can be transformed into environment-friendly materials.
