Abstract: Low-temperature highly icy frozen rocks (up to minus 7.0°C) and productive formations with temperatures up to 55.0°C under high temperature gradient values (3.3°C/100 m) and small depth, in Bovanenkovo oil-gas condensate field, create conditions for heat transfer from the reservoir to the wellhead with subsequent impact on the surrounding permafrost, including their warming and …

One can add to these intervals the misinterpretation of geophysical well logging, as a result of drill mud colmatation into the formation or …

The first stage of development of oil fields is associated with the use of natural energy of the …

Coal mining and thermal power plants (TPPs) are two multi-activity-centred coal-based sources that affect the ambient air quality of the region. Among five air pollutants under consideration, the annual average concentration of PM10 and PM2.5 …

Object: The purpose of this study is to develop …
Read moreAbstract: At present, the research on enterprise performance of domestic and abroad mainly focuses on the enterprise’s operating efficiency. The research based on environmental costs assessment of enterprise performance, especially the measurement method, is still lacking. In this paper, the environmental costs of the coal industry enterprises are divided according to the life cycle of …

What are the focus and requirements of organization in the multi-project? Where are the links to organization objectives? Further the aim is to provide a organizational methodology for the risk management in multi-project …

The key to improving the performance is measuring it with a suitable method and then compare it with the standard one to assess the current status of performance. With the increasing effect of …
Read moreAbstract: In the mining industry, the rock breakage by drilling and blasting plays a vital role as it facilitates not only fragmentation of rock mass but also controls consequent mining operation. In order to increase the production capacity or prolong the life of the deposit, the expansion of mine is unavoidable. However, when the mines …

Read moreAbstract : Operators of opencast heavy earthmoving machinery (HEMM), during their 8-hour shift duration, are regularly succumbed to the high level of whole body vibration (WBV) amplitudes. Due to long and continuous working in the field, the operators of HEMM may yield to adverse health effects and results in hazardous conditions if the magnitudes repeatedly …
