ABSTRACT

Purpose. To solve the problem of efficient development of rare and precious metals by creating optimal design technology and propose a new approach to the design of layout of ore deposits with reserves of rare and precious metals.

Methods. To model the process of development of a particular field used methods of dynamic programming, the choice of rational production volume made by comparing marginal costs and income and taking into account the environmental aspect of the development of the field. The paper presents numerous specifications of the development of valuable ore reserves, which can be displayed in a mathematical model of the state of reserves throughout the entire period operation of fields. Evaluate and make a choice in different geological, territorial and social conditions, taking into account the great variety of forms of ore bodies and high value of the mineral, possibly based on dynamic programming.

Findings. The results of modeling the strategy of development of gold deposits with a specialized program of dynamic programming, the calculations of the rational volume of metal production at the real field and an example of constructing an alternative version of the ecological strategy for the development of gold deposits are presented. Modern methods are described for determining the profitability of exploiting real reserves of gold field, which show the possibilities of efficient development of high-grade ore resources, as well as creating powerful anchor projects for building up our own mineral resources sector of Ukraine.

Originality. It has been a model of changes in the state of the balance reserves of home made fields is describes, taking into account the current and compulsive antecedents for dynamic programming. A method of optimizing the model is given and software calculations are recommended.

Practical implications. We developed the system for decision-making support, which allows optimizing operational parameters of layout of ore deposits with reserves of rare and precious metals.

Keywords: rare and precious metals, opening of a deposit, dynamic programming, inventory status, algorithm, software, optimization, effective operation, anchored project, investment attractiveness
