Аннотация: Рассмотрены вопросы использования твердых бытовых и про- мышленных отходов, остатков сточных вод для рекультивации открытых горных выработок, а так же условия их захоронения, предотвращающие переход чужеродных загрязняющих веществ в подземные воды, установившихся гидрологических режимов. Применение Остатков сточных вод для восстаноПоказать полностьювления нарушен- ных земель позволяет улучшить плодородие земель и сократить сроки рекультивации. AND PROCESSED WASTE WATER Under discussion are the issues of utilization of solid residential and industrial waste and waste water for reclamation of open pit mines, as well as their disposal conditions toward prevention from the transfer of foreign polluting substances in underground water under sustained hydrological regimes. The use of waste water residue in reclamation of disturbed lands allows enhancing soil fertility and reducing reclamation period. Open pit mines can be used for the disposal of solid residential and industrial waste of hazard class IV-V and untreated and treated residue of waste water for the improvement of biological properties of soil in the course of disturbed land reclamation. Based on the experimental results, the method of combination of actual process stage of open pit mining land reclamation and preparation stage of underlying layers and fertile soil is proposed. The method consists in the stage-wise reclamation of open pit mines, where the first stage is filling of mined-out void with overburden nonhazardous in terms of contamination of underground water, brought from external dumps and overlaid by the partition layer made of water-proof clay, the second stage is filling of the mined-out void with solid residential or industrial waste of hazard class IV-V, with the water-proof clay partition, the second stage is flattening of pitwalls, and the fourth stage is the formation of a fertile layer from production or potentially productive soil. The scenarios of the fertile layer formation, given the availability of various waste, may be out of number and depend on amount of useful substances and selected plants, and on many other factors that condition economic expediency of utilization of the materials.
