The analysis of technological failures at energy facilities of the Kemerovo region is given. It shows their dependence on the time of the year, the cities where the energy facilities are located, and the type of power plant. Statistical data on the distribution of technological failures (TF) due to various reasons are provided.The analysis of technological disturbances of energy enterprises of the Kemerovo region is given. Their dependence on the time of the year, cities where energy enterprises are located, as well as the type of energy enterprise is indicated. The statistical data on the distribution of technological disturba nces for various reasons are presented.
The Smart Grid system become to apply all over the world. It provides significant efficiency increasing of power supply networks by supporting its balanced load. The key design features of each Smart Grid system depend on individual characteristics of particular power supply network which are determined by the structure of its electrical energy consumers. Relating to Kuzbass open-pit coalmines it is necessary to take into account the nonstationarity of its power supply scheme, the strict requirements of power supply reliability and the high capacity of consumers. This article is connected with the "Kedrovskiy" open-pit coalmine and describes its power supply scheme and the structure of its consumers. The downtimes and electrical equipment failures are analyzed and the connection between the number of emergency downtime and the number of working excavators is found out. The load of "Kedrovskiy" power distribution network is calculated for the strip mining operation. The results show power distribution network under consideration does not provide the effectiveness functioning and the implementation of Smart Grid is a good decision. There are the structure and design calculation of proposed Smart Grid in the article. It is finally depicted that Smart Grid" system decreases the downtimes of electric equipment and increases the power supply reliability.
The article discusses the risks and factors of electrical safety that affect the working person. Electrical injury, in comparison with other types of industrial injuries, is a relatively small percentage, however, in terms of the number of injuries with severe and fatal outcomes it takes the leading place. That is why the utmost attention must be paid to the issues of electrical safety. You need to understand how electric current affects the human body, the conditions for falling under dangerous voltage, measures to protect against electric shock. The article is of great practical importance both for those interested in electrical safety issues and for employees of enterprises in the mining and energy industries.
The national project “Ecology” sets to bring up to date the ecological policy of the environment-geared laws of the Russian Federation which must preserve biodiversity and afford the involvement of all participants in the process. Revegetation, as part of the program, sets to restore disturbed lands to a condition suitable for their use in the national economy and prevent their anthropogenic impact on the adjacent areas. The quality of reclamation works is not always at an adequate level, which creates difficulties in the remediated lands development. This is a consequence of insufficient information at the design stage, specifically data on the composition and properties of the soil cover and worked-out rock mass, lack of special technical support for the implementation of remediation measures at the proper level, the landscape of the deposit is not taken into account during the work with disturbed soils. Intensive use of the studied territories of the Sartakinsky, Karakansky and Mokhovsky fields both in agricultural and mining industries led to changes in the natural biocenos. This paper presents the study of soil-agrochemical characteristics (granulometric and structural structure of soil, the humus content, hydrogen index, the content of food elements, hydrolytic acidity, the sum of absorbed bases, absorption capacity, etc.) on different genetic horizons of zonal soils of Mokhovsky coal mine, and specifically unbroken soils of Mokhovsky, Sartakinsky and Karakansky fields on possibility of their use at carrying out of biological reclamation.
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.
