Remote sensing of the Earth as a part of research of assessing the volume of technogenic raw and the environmental situation during the exploitation of placers

Abstract

It is known that one of the main nowadays problems of subsoil use is the depletion of reserves. Every year many researchers pay attention on mining waste as a source of replenishment of the resource base. Disputes on the prospects of processing technogenic raw materials are relevant. The object of research is the technogenic neoplasms, which were the result of dredging and hydraulic processing of placer gold. The paper presents the results of assessing the prospects and places of application of information technologies, in particular, the analysis of Earth remote sensing data in the design and organization of work to involve technogenic placers in operation. It is shown that these technologies are able to increase the efficiency of work and reduce labor costs at the stage of preliminary study of potential development targets.Possibilities of detailing the infrastructure facilities of the mining and processing complex are considered. It is proposed to use the vegetation index at a non-traditional time for vegetation research in order to isolate coniferous trees on the formed secondary phytocenoses. An area assessment of the technogenic raw materials of the Kerba gold-placer cluster has been carried out. The analysis of the methodological approach based on remote sensing data is carried out. Aspects of natural vegetation restoration in the post-exploitation period are covered. Optimal combinations of raster data channel combinations for the study of the territory within the boundaries of the object under study are proposed.
