ABSTRACT
Objective is
to propose a new approach to investment allocation in the group of
coal-mining enterprises.
Methods. To
solve the specified objective, a complex approach has been applied
including assessment of enterprise investment attractiveness, determination of production potential, and definition of the possibility
to switch to a break-even mode. The process
of planning the ways to
save industrial potential of coal-mining regions may be considered
as the representation of multidimensional space (initial and design values) in terms of
the one-dimensional (amount of investment
money) one.
Findings. It
has been established that the stage dealing
with the development of a model for managing
processes for mine unprofitability reduction should involve consideration of 8-10 factorial features, which may determine the formation of economic potential, taking into account peculiarities of the remaining deposits and their quality, as the integral
assessment of mine potential in terms of
both state and non-state investments. The formulated objective means selection of the minimum
number of factors, which would reflect in the most
adequate way the internal potential of a mine expressed by economic added value – as a consequence of interaction of factors of coal mine
economic activities in specific mining, geological, and technological conditions.
Originality of the research is in the fact
that it is expedient to use an
indicator of economic reliability, which synthesizes the capacity of links, economic
level of technical and economic indicators, and the amount
of remaining deposits, as a complex component of the level
of an unprofitable mine. The mentioned indicators determine the residual life of the
mine. Their physical content is not identical;
and it is the fact
that helps (in terms of
their joint use) obtain more complete estimate than when using any single indicator.
Practical implications. Practical significance includes actual assessment of the state of
Donbas coal enterprises and determination of marginal break-even indicators, which has made it
possible to elaborate recommendations for attracting financial resources.
Keywords: coal mines, coal-mining
region, break-even, modelling, diversification, potential, reserves
