the paper considers the problem of preserving water quality of rivers, in the channel and floodplain part of which gold deposits are developed by open-pit mining. As a result of the study we have developed the simplest engineering solutions for the design of environmental hydraulic structures. Designs of these structures were implemented in the project of Korolevskoye alluvial gold deposit in Transbaikalia. The operation of these structures during the washing of gold-bearing sands in the floodplain part of the Amazar River prevented the contamination of its water by industrial wastewater. The...
the paper considers the educational process built with the help of practice-oriented technologies. It brought academic railway disciplines studied by higher education students closer to their future profession. Necessary conditions for purposeful formation of competitiveness of participating students as future specialists were created. Students master the profession of railway engineer not only from textbooks and drawings, but directly including in its simplest forms. The students, participants of this educational process have formed: system thinking; developed skills of teamwork in the mode o...
the chapter is devoted to the study of river ice formation factors and determination of their parameters in natural conditions. Hydrodynamic pressure in ice hillocks affects the stability of structures. The authors consider the modes of frost formation, establish the processes of intensive formation of ice in the upper and lower parts of the stream, and propose calculation dependences for practical application.
