Abstract

The physical and mechanical characteristics of coal seams, immediate floor and roof significantly influence to the choice of systems (the methods and technologies) of coal underground exploitation, and in this paper, their grouping and sorting by importance for the conditions of active underground mines in Serbia was carried out. The research is based on the results of laboratory tests performed in all mines, on the basis of which individual parameters were evaluated. The results of the research proved the complexity of the choice of excavation system in the specific conditions and individual limitations.
