Abstract. Mining of open pit exerts a huge negative impact on the environment. Maximal impact is subjected to land, which before mining, as a rule, were used in human activities. Each year, only 80% of total area disturbed by mining operations are restored.

The topicality of the issue is amplified by the fact that the existing technological reclamation scheme can only partially restore a disturbed land in order to use it as it was used before the man-caused disturbance. Thus, agricultural lands which were allotted for and disturbed by mining can be reclaimed only by 50% of the original use. The article presents a new technology of forming dumps with a common surface area, which can improve efficiency of reclamation works at mining a great majority of horizontal deposits.

Keywords: open cast mining, reclamation, dump.
