Mass transfer of dispersed particles in water filtration in macro-grained media

Abstract: Mass transfer of dispersed particles in filtration of water in waste dump is considered. The established dependences between filtration parameters and structural characteristics of suspensions and filtration media are used to predict degree of water purification and to identify parameters of filters manufactured from mining wastes.

Justification of Open Pit Mining Technology for Flat Coal Strata Processing in Relation to the Stratigraphic Positioning Rate

Abstract: The article describes a problem of considering the coal strata bedding for the scheming of dragline mining technology for open pits developing flat seams. For three flat coal seams strata processing the main criterion defining the choice of technology of their processing is the stratigraphic positioning rate for the middle coal seam. It is the ratio of the upper and lower interbeds height. Based on the fact that it is possible to process coal strata with two methods—the consequent and the simultaneous ones, it is necessary to define the limits of the effective using of these methods. The consequent method (with the shift of upper overburden cut) provides alternating explosion and excavation of the upper, and later—the lower interbeds with transferring the rock into internal dump. The simultaneous method is based on synchronous blasting and transfer of the upper and the lower interbeds. It is important that this method does not provide overburden cut shift. As the result the detailed analysis of the methods of excavation and re-excavation of rock array under dragline mining method allows optimizing technical and economic indicators of three flat strata processing. The research results are presented on the example of Southern Kuzbass (Kemerovo region, Russia) coal deposits being developed by several open pit mines.

Convergent and Nature-Like Technologies as the Basis for Sustainable Development in the 21st Century

Abstract: The global challenge of the 21st century is associated with the need to ensure the sustainable development of modern countries. The basic condition for such development is an adequate amount of energy and resources. This means using not oil and gas only but supplies of drinking water, arable land, forests, and other mineral resources are being rapidly depleted. The industrial civilization, in only 200 years of its existence, has put the world on the threshold of a resource collapse. The reason for the current crisis situation is the antagonism of nature and the technosphere created by man. Technical progress has violated the natural resource turnover – a peculiar metabolism of nature, creating technologies that are hostile to it. These technologies, being torn from the natural context, are in fact bad copies of individual elements of natural processes and are based on a highly specialized model of science and industry-specific technologies. Consequently, the transition to sustainable development requires a radical technological modernization of the economy, in particular, widespread diffusion and inter-sectoral transfer of convergent and nature-like technologies.
