Additions and amendments have been made to the methodological foundations of a comprehensive assessment of the environmental impacts caused by mining industry complexes:
      Methodical recommendations have been developed on making predictions of ecological zoning in the conditions of open and underground mining of mineral deposits;
    Methodical recommendations have been made on predicting environmental impact consequences within the specific ecological zones using a substantiated system of indicators;
      Methods and an algorithm have been developed for an appraisal of the economic damage to stocks of materials and capital equipment, to natural resources and population, caused by mining industry complexes as a result of their impact on the environment.
    The performed research plays an important role in substantiating administrative decisions on improving the ecological situation in mining regions.

   For mining industry complexes, the new aspects of the environmental impact assessment are as follows:
• Classification of environmental impacts have been done
• Predictions have been developed depending on specific ecological zones
• The appraisal of the economic damage caused by allocation of lands and by the environmental pollution outside the allocated lands is conducted
within specific ecological zones using the methods of direct costing and indirect assessment
• Assessment of economic losses due to the environmental damage is based on the assessment of decreasing value of natural resources
• Cost assessment of social consequences is based on the risk theory.
