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.

Purpose. Theoretical substantiation of the principles and recommendations development as for the development of manganese ore products of domestic mining companies' competitiveness on the basis of the application of the ecologically-oriented approach to management of their production and sales activities. Substantiation of the methodical approach to the estimation of the impact of the level of implementation of environmental protection programs of the mining enterprise on the formation of the technological cost of its products, which is the basis of its successful advancement in the market. Methodology. The following methods were used in the course of the research: the method of theoretical generalization and systematization (for determining the peculiarities of the formation of competitiveness of domestic producers of manganese raw materials, depicting the main tendencies in the development of the manganese market, defining the directions of implementation of the ecologically-oriented management of production activities of the mining enterprise), the statistical method (for displaying indicators that characterize the production activity of enterprises producing manganese ore), the analytical method (for definition of the factors affecting the competitiveness of manganese ore from local producers). Findings. A methodical approach to the formation of the competitiveness of the mining company products is proposed on the basis of the conducted research based on the introduction of ecologically-oriented management of its production activities, taking into account the environmental consequences of the development of the deposit and the costs associated with them, in determining sales volumes and components of pricing of manganese ore products. Originality. A methodical approach to the formation of the mining company products competitiveness is proposed based on the introduction of the ecological-oriented system of its production and sales activities management, which implies significant impact of the level of environmental protection programs implementation of the enterprise and measures for more rational development of the ore deposit to reduce the technological cost of production as a key factor in the formation of demand for manganese ore raw materials at the domestic and foreign markets. Practical value. The obtained results are aimed at improving the methodological bases of the mining company competitiveness management with the use of pricing methods for its formation. Consideration of the influence of environmental factors on the development of the mine on the competitiveness of manganese ore raw materials will allow defining purposefully its cost characteristics, favorable for increasing its demand in the market.
