Abstract.

The operation of mining enterprises leads to the disturbance of the land surface, the violation of aquifers and adjacent areas contamination. In mining regions there are high levels of environmental objects pollution, which significantly impairs on population life conditions. That is why there is a need to improve the technological schemes of land technical and biological reclamation that has been affected by the long-term mining of mineral deposits.

An original approach is proposed to determine the sequence of mining technology land reclamation technology in the process of horizontal deposits development (pit building, mining deposit and before pit closure). Research of the reclamation works technology in time is carried out according to the three schemes that were first proposed in this article. The calculated formulas for determining the areas of land that are violated by mining operations and the area in the internal dumps that are consistently restored to a condition suitable for agriculture using are given. An example of the proposed approach practical realization to modelling the processes of extraction of chernozem, potentially fertile loamy loams and their placement on internal dump according to conditions of the Nikopol manganese-ore basin is given. The measures complex aimed at the restoration of land disturbed by surface mining and their return to a suitable condition for agriculture sector is substantiated.

Implementation and application of the developed technological solutions will reduce the negative impact of mining on the environment at the mineral deposits development. The developed methods of choosing technologies for protecting ground water during mining minerals can improve the ecological condition of mining regions and contribute to the sustainable functioning of the mining industry in Ukraine.

Key words: mineral deposits, mining land reclamation, chernozem, loam, external dumps, internal dumps, stages of deposit development.
