Purpose. The purpose of the research is substantiation of criteria to estimate land-conservation procedures in terms of open-cast mining which would demonstrate land-restoration level as for the degree of its disturbance and scale as well as for its valuation base. Methodology. Technical and economic methods as well as method of system analysis have been applied to determine parameters of efficient mode for land resources during open-cast mining; to define current tendencies of sheet ground mining technologies progress as for their relation to the level of land conservation, the method of scientific generalization and systematization has been involved. Findings. A mode of mining land use has been characterized regarding the development of favourable conditions for conservation of lands used during open-cast mining. The indices of land conservation in terms of the area of its disturbance, their ecological properties and cost estimation have been defined. Methodological approaches as for the selection of technological schemes of open-cast mining in terms of land conservation have been substantiated. Originality. Dependence of technogenic load on land of mining allocation and the level of ecological and economic efficiency of open-cast final mining as well as further restoration of disturbed lands has been determined. That should become a background to define a direction of post-industrial use of the restored lands. Practical value. A system of indices has been proposed which is methodological foundation to plan mining objects at the stage of open-cast final mining according to the criterion of minimization of volumes of mining land allocation and development of favourable conditions to restore the lands disturbed by mining.
