ABSTRACT
Purpose. To develop a new
approach to the effective development of mineral deposits by creating
optimal design technology.
Methodology. To model the
process of developing mineral deposits, a dynamic programming model is proposed that allows you to develop strategies for
the optimal process of designing, developing, operating. To make decisions
at the stage of parameter estimation, a decomposition approach is applied.
For decision making, algorithms and methods of
dynamic programming are proposed.
Findings. A new approach to
the estimation and selection of parameters is presented, a characteristic
feature of which is that the mineral itself is not considered “as a final
product” that should be extracted, but only as an intermediate link in the
structure of energy generation, metal smelting, etc. This allows us to
consider operation process due to changes in stock status, which in turn
forms a development strategy. The development strategy provides for the
construction of scenarios (economic, environmental) within the framework of
which a "narrow" task is solved related
to the organization of work, cost optimization, etc.
Originality. For the first
time, a mechanism is described for shaping the
efficiency of field development, which provides for a hierarchical
structure based on the category of “quality”, which in turn forms
strategies; strategies form scenarios, and scenarios contain parameters;
optimization of each parameter involves the assessment of priority control
factors. For the first time, an algorithm has been
proposed for the optimal design of development of a mineral deposit,
which involves determining the volume of production, minimizing risks,
determining parameters that meet the optimality criterion and their further
optimization.
Practical
implications. For the first time, methods and results of studies on the optimal
design of the exploitation parameters of deposits of valuable minerals of
Ukraine are proposed, which are the basis of the
methodology for solving complex problems of optimizing the parameters of a
mining and processing enterprise and correspond to the modern level of
information technology.
