Abstract: Kuzbass accounts for more than 58% of coal production in the Russian Federation, and about 80% of the production of all coking grades. Most of the reserves are available for open-pit mining, they lie at a depth of up to 300 meters, and about 40% of the reserves are concentrated in the formations of the shallow fall of the central and southern parts of the basin. With the open development of formations of shallow formations, the main type of technology is transport and transportless. The deposits where the transportless technology is presented are distinguished by a variety of mining and geological conditions. Depending on the laying of the rock in the internal dumps, the transportless technology is divided into a simple one, when the rock is placed directly into the dump, and a complicated one, part of the overburden is excavated repeatedly. With an overburden capacity of 15-20 m. it is possible to use a simple transportless technology with a single transshipment. At an overburden capacity of 30-40 m. complicated multiple transshipment is used. The stripping capacity of the non-transportable technology is limited by the technical capabilities of the dragline. At the Kuzbass sections, according to the transportless technology, mainly from one to three tiers of the internal transportless dump are poured out, with further increase, the coefficient of overexcavation sharply increases and the productivity of ASH excavators decreases, which is due to the use of the most common "Raichikhinsky" scheme of excavation. Based on taking into account the patterns of occurrence of the formation of shallow layers and the main parameters of the quarry field, a phased development of the deposit is proposed with the creation of an initial capacity for an internal transportless dump and the possibility of increasing the capacity of overburden rocks handled using transportless technology in a coalless zone.
