Abstract: In the general technological policy of open-pit coal mining, there are stable trends towards a rational combination of solid mining and a thrifty attitude to the environment. Nevertheless, the significant disadvantages of the systems and technologies used include the dumping of external dumps, entailing the alienation of land and a long range of transportation of overburden by quarry vehicles. In general, this leads to an increase in production costs. A significant proportion of open-pit coal deposits in Kuzbass are represented by inclined and steeply falling formations. The completed projects for some sections provide for the use of resource-saving technological solutions with internal dumping, based on the use of transport methods for developing the downhole side of the quarry field, in which all overburden from the faces is transported to the internal dump by dump trucks, which reduces the efficiency of mining operations. This publication discusses the possibility of using a less expensive transport-free technology for the above conditions. The use of this method, both in production and in design practice, is hampered by the lack of a comprehensive methodological framework. For example, there are no recommendations for assessing the depth of the initial excavation for an internal dump, the mining regime is not defined, etc. The article solves the intermediate tasks of establishing the preliminary technical boundaries of the transportless technology for moving overburden rocks from the face to the inner dump with a continuous deepening system open-pit mining of inclined and steeply falling coal deposits and identified by performing mining and geometric analysis.
