At the quarry fields with inclined and steep occurrence of complex structural coal seams formations of Kuzbass, it is preferable to use transverse mining systems. In this case, transport costs are significantly reduced and alienation of land areas for external dumps is reduced too. It is also possible to apply an effective transportless technology of stripping operations. Absence at this technology of expensive and ecologically dangerous quarry dump trucks allows extracting coal with smaller expenses, makes it more competitive in the domestic and foreign coal market. However, for the design of such technology in the conditions of transverse direction of the mining front, at present, theoretical studies of issues related to the justification of its parameters and the choice of mining equipment are insufficient. A wide range of coal bed formation conditions, a wide range of standard sizes of draglines used in the transportless technology, as well as various values of the depth of mining predetermine the multi-variant solution of the above problems. In this case, the formation of possible variants of mining operations with the use of certain models of excavators for their subsequent evaluation by any criterion is in itself a rather complicated task.
