Abstract. Abstract. The article describes a new method for determining optimal combination of the treatment equipment. Rational technological chains of treatment equipment for the seams with thickness of 0.90 - 2.60 m were determined on the base of analysis of factual performance indicators of the fully-mechanized longwalls in Donetsk and Dnipropetrovsk regions. Each seam thickness range corresponds to certain universal graph of alternatives to be chosen. Graphical display of factual interrelations between the set of equipment and parameters of the opencast coal development demonstrates rational domain of the mining equipment operation. It is stated that, while searching an optimal set of equipment, if productivity of the ―support - combine -conveyor technological chain is at the high level then such set of equipment should be considered reliable for the given geological and rock parameters, and sets of equipment with minimum daily load should be considered non-rational and undesirable. Formalization of the graphs and displaying them in the form of networking models allows to determine the most desirable set of treatment equipment in context of minimizing of optimization parameter; besides, it is possible to arrange a mechanized complex at the level of ―support - combine and ―combine - conveyor. The software described herein allows to automatize processes of searching for optimal sets of mechanized complexes and optimize technological chains of treatment equipment.
Keywords: Key words: mechanized complexes of treatment equipment; algorithm optimization; statistical analysis; graph theory; network model.
