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 of discussions to find ways to solve assigned tasks; developed the ability to think independently; increased interest in the profession of a railway engineer. These qualities, necessary for a specialist, were manifested and consolidated by the students who participated in the research work on strengthening the railroad track at 6101 km of the Trans-Siberian Railway.
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 use of a water circulation system in the technological process and the filling of settling tanks with filtration and rainwater gave a positive water balance of the deposit. These measures prevented the impact of gold mining on the Mogocha municipal water intake located near the facility. As a result of technical and biological reclamation of disturbed lands during the development of the deposit, this area may serve as a recreational zone for Mogocha residents. Profitability of production and its economic efficiency are established by economic calculations given in the study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
