Ecological Systems and Devices Annotation << Back FEATURES OF THE DEVELOPMENT PROCESSES OF TECHNOGENIC POLLUTION OF WATERCOURSES BY FINE POWDERS IN THE DEVELOPMENT OF ALLUVIAL SYSTEMS IN WATERSHEDS OF MAJOR RIVERS Yu.P. Galchenko, V.I. Lebukhov The paper discusses the processes of formation of technogenic pollution of natural watercourses in the development of mineral powders fl uvial placers in catchment systems of large rivers. It is shown that the environmental consequences of conducting mining operations are determined not only used geotechnology, but also structural features of the river system, the nature of the distribution in the extractive industries and its particle size distribution of mineral slurries formed during mining. First established that the sedimentation stability of the particles in the aqueous medium increases not only as a result of the concentration of particles, but also the seasonal water temperature drops. A new method for quantifying the cumulative assessment of the development process of accumulation tonkodisperspersnyh suspensions in an aqueous medium at teamwork contiguous mining companies. The intensity of the process of accumulation tonkodisperspersnymi suspensions increases in direct proportion to the number of enterprises and reduce the order of the watercourse in the river system. Keywords: Placer deposits; drainage system; the order watercourse tonkodisperspersnye slurry cumulative savings; environmental impacts. Contacts: Е-mail: schtrek33@mail.ru Pp. 03-08.
