This paper explores the utilization of mine structural models in optimizing operations at the “Pniówek” coal mine, focusing specifically on monthly data regarding the proportion of barren rock extracted alongside coal and its origins. Highlighting the significance of monitoring barren rock extraction in underground mining, with “Pniówek” serving as a case study, the article delves into the adverse effects of excessive barren rock in the Coal Mechanical Processing Plant feed and its consequent impact on daily plant performance. Furthermore, it elucidates the journey of excavated material from longwall extraction through processing plant operations to the final products. Subsequently, the paper presents a detailed analysis of coal yield, its composition, and a graphical representation of gangue proportions using Gantt charts. Additionally, it provides insights into forecasting gangue proportions in extraction, along with methods for interpreting and leveraging the obtained information for further operational optimization.
