| Summary: | An analysis of the results of the reproduction of land in an open development of a horizontal mineral deposit has been carried out. The interconnection of the method and the system of open development of the deposit with the qualitative and quantitative levels of land reclamation, as well as their monetary estimation according to the direction of use, is substantiated. The principle of this approach to the planning of land abandonment measures at a mining enterprise from the point of view of the subordination of the technological processes of mining of minerals to the results of the reproduction of land in previous periods is proposed, which allows to take into account the quality of reproduction of land for determining the extent of their violation. The technological scheme of organization of mining works and land reclamation works is shown, which involves synchronization of these processes in terms of disturbance and reproduction of lands, as well as formation of a more qualitative soil layer due to its selective displacement. The components and peculiarities of the formation of the economic effect are determined from the introduction of dynamic schemes for the development of a quarry field on their relation to the cost of land leakage in the development of horizontal mineral deposits in the stages of the life cycle of a quarry.
