Sizing the production capacity of underground coal mines is an extremely complex task with a number of specifics that must be taken into account when designing the mines. The main factors are the specific natural-geological conditions of the deposit, which determine the application of an adequate excavation system followed by organizational factors, which in combination gives the most favorable production, economic and safety parameters.
This paper presents the specifics of production capacity design in active underground coal mines in Serbia, based on a comprehensive analysis of the influencing factors. Of special importance is the ranking of the impact of natural and geological conditions on the excavation system, with four groups with the qualitative analysis.
