The problems of underground exhaustion processes on the example of iron ore deposits of Kryvbas are studied. As objects Kryvbas deposits of different geological and mining types were selected. The methodology for forecasting of the costs for post-liquidation development of licensed areas, which is based on the experience of European countries has been proposed. These ones are with the most evident signs of intensive development and exhaustion of mineral resources. Valiavkinske Banded Iron Formation deposit is characterized by extraction intensification and dangerous changes of geological environment. The Pivdennyi Quarry with reserves of previously lost rich ores has most of exhaustion phase signs with prolongation of extraction in complicated mining conditions. The ecological-geological and geological-economic indicators of intensive exploitation of mineral deposits are compared and formulas for environmental costs calculations on objects are given.
