This paper presents the methodology of determining and analysis results of the limit production capacity of coal in the roof exploitation zone of the open pit Gacko-Central Field in a function of configuration and parameters of the combined system. The coal exploitation system at the open pit Gacko-Central Field mine is a system of exploitation characterized by the complex conditions under which it operates, with the use of continuous, combined and discontinuous coal and waste exploitation systems. It is also characterized by the existence of two spatially dislocated sites, in which the exploitation is carried out under significantly different conditions. A complex solution for coal exploitation is the result of optimization a large number of mutually determined technological processes and systems, both in terms of the possibility of applying a certain complex of mechanization, as well as in terms of individual capacities at the site of excavation. As a criterion for success the exploitation system, a unit cost of exploitation was adopted including the capital and operational costs of a variable part of combined system.
