ECONOMIC-MATHEMATICAL MODEL OF RAW-MATERIALS RESERVE REPLACEMENT ON THE BASIS OF RAW-MATERIALS POTENTIAL


Dadykin V.S.

The basic model of raw-materials reserve replacement is the dynamics of utilization and development of the mineral resource base determined by the interaction of the extractive industry, which reduces known reserves, and geological exploration revealing new deposits. The consumption of minerals forms the demand for their extraction, which is ensured by the repayment of the equivalent mass of reserves. The balance in the system "consumption - production" is determined by a direct and rather severe impact of economic factors. Excess of production over consumption causes, as a rule, a fall in prices for mineral products and leads to a reduction in production (primarily in low-margin fields). Mining under all conditions depletes the mineral and raw materials base and thereby creates a demand for its reproduction, which is satisfied by geological exploration. They provide an increase in industrial reserves from previously identified low-grade reserves (exploration). The preparation of facilities for exploration is carried out through general search and assessment of reserves and forecast resources. Keywords: geological and economic monitoring, raw-materials potential, mining zone, geological exploration, industrial and raw-materials unit, industrial and raw-materials object. Highlights: • with the aim of eliminating the existing imbalance in the growth of stocks and their consumption, it is necessary to develop the economic-mathematical model designed to estimate the level of reserves reproduction; • subsoil use objects - it is advisable to classify potential sources of raw-materials reserve replacement according to the level of liquidity, i. å. opportunities to be operationally involved in the sectors of the national economy; • the most important task for the near future is to develop the mineral resource base (SME) at the expense of forecasted facilities (and their resources) in the areas of existing mining enterprises.
