Abstract: The coal deposits of the Kuznetsk basin, developed in an open-pit manner, are characterized by difficult conditions, with a large extent and a significant depth of formation formation, their different thickness and angle of incidence, high strength of the host rocks and others. In the geological and economic regions of the basin, deposits with formations ranging from gently sloping to steeply falling are mainly represented. A common feature of the disadvantages of existing technologies is the increase in the current stripping coefficient during the deepening of mining operations, which implies an increase in the number of mining transport equipment to maintain the achieved technical and economic performance of mining enterprises, but this does not always allow changing the situation with the existing principles of organizing work inside the working area of the quarry field. In this publication, the main attention is aimed at performing an analysis of the mining conditions for mining a formation of shallow formations, which showed that existing approaches do not fully meet the formulated requirements for development technology to ensure complete, cost-effective and safe mining of coal reserves in the boundary contours of the section. This served as the basis for carrying out a study aimed at creating conditions for effective and maximum possible environmental safety while optimizing integral efficiency indicators during field development in the boundary contours of the section by justifying the mining regime. The object of grapho-analytical modeling is the gently falling deposits located in the central and southern parts of the basin. Thus, the purpose of this study is to develop the basic principles for the formation of structural schemes for the sequence of mining of quarry fields of coal mines.
