Abstract.

Modern the technology to extract and process rock mass have proved studies basic sources ore losses, what act to the technogenic objects: losses commercial ores from the stoping faces, non-commercial, they are not subject to record, oxidized ores which should be stored in a separate storage or dump and dry wastes of a processing plant. Required that ore losses and dilution while mining are determined by following mining, technological and technical parameters of open-pit mining operations. Determined that ore losses in an open pit depend polynomially upon technical characteristics of the equipment being directly proportional to the contact zone angle and inversely proportional to the processing volumes. A technique to process rock mass from hard-rock technogenic media has been developed, it is aimed at recovery of mineral losses, restoration of the environment at the territory of mining enterprises by means of rock mass extraction, its processing and redistribution for the purposes of land recultivation and landscape restoration. Classification of dry ore-containing hard rocks of dumps has been developed; that has made it possible to improve technological scheme of the processing of rock mass from technogenic media, emphasize its variants of use, and specify the required facilities and their productivity. Classification of hard dry dump rock is as follows includes of origin rock mass, reserves purposes, mineral type, rock mass lumpiness and specific magnetic sensitivity. Scientific value of the paper is in determining the effect of changes in the losses in pre-processing dry wastes upon the yield of industrial product and wastes; the effect has demonstrated that the yield of industrial product is in polynomial dependence upon the pre-processing losses while yield of tailings is in the power dependence. Practical implications of the paper are in the fact that the proposed method helps form mesorelief with the properties close to the natural one, it is involves restoration of the initial landscape with the help of opening hard rocks followed, completed by laying water-bearing and potentially fertile layers.

Keywords: open-pit mining, technogenic and disturbed geological environment, mine dump formation, reclamation, restoration of landscape.
