The paper presents preliminary research conducted to determine the thermal condition of the main belt conveyor transporting coal from the longwall. The results show the thermal condition of the conveyor and in the further stage are used to effectively diagnose possible causes of damage to the belt conveyor’s drive unit. The tests were performed on the conveyor whose operation is strategic to the mine. The research comprised a thermal imaging camera that allows taking contact-free measurements. The main purpose of a thermal imaging measurement is to detect changes in thermal conditions without the need to stop the conveyor belt. The paper presents the methodology and discusses the manner of performing underground measurements as well as a procedure for processing the results. The final conclusions concerning the technical condition of the drive unit were based on the results and their analysis.
The purpose of the software development presented in the article is to obtain detailed information about the surface of the walls in wells necessary for more efficient and safe drilling and casing of the wellbore. The developed software of the automated system “LogPWin” allows obtaining a clear idea of the mine itself, as well as reducing the time spent on processing and analyzing the model obtained during the logging process. A software product developed as a result of the work provides visualization of data coming from an acoustic profiler, giving a visual and informative idea of the object of study. The program gives detailed information about the surface of the mine’s walls through 3D modeling. It possesses the possibility of rotating and scaling the object; there is also a color palette that can be changed depending on the incoming data. The program can be applied in the oil and gas industry and mining, as well as when drilling wells for other purposes. The program interface is quite clear and simple. The structure of the program is made in such a way that it allows obtaining data for building an object not only in real time, but also through interaction with a ready-made .txt file.
Sustainable development is a symbiosis of technological and social progress, as well as responsible environmental management, should not rely on old industries that actively consume non-renewable natural resources, but on new, convergent-technological ones. In this paradigm, the environmental safety of future generations is formed by structural shifts in the economies of advanced countries caused by the expansion of technological convergence. Technological convergence -the result of accelerating scientific and technological progress in the 21st century -has a transformative effect on the economies of developed countries, forming a new type of sectorial genesis. It is not related to the deepening of sectorial specialization or inter-industry cooperation within the framework of the evolution of basic technologies, but to the emergence of technologies of a fundamentally new type, formed as a result of the merger of know-how from different industries. The structural shifts arising from technological convergence do not have the historical analogues and forms of regulation developed by industrial policies of developed countries. The article outlines the key statements of the the impact of convergent technologies on the structural base of sustainable development.
The transition to an industry that implements a closed production cycle (resource recycling) is in demand due not only to the growing environmental problems of the industrial economy, but also due to the prospect of diffusion of Industry 4.0 technologies. Opportunities, on the one hand, to involve secondary raw materials in production to reduce material costs and operating costs, on the other hand, to use the potential of information technology, are revealed in the system of interaction between the state, science and production, as well as the entire society, called "Tripple", "Quadruple" and "Penta" Helix of innovative development. The importance of
The life cycle of mines lasts from several years to several decades. The closure of the mine occurs when its recourses are completely extracted, or mining is no longer profitable within its leasehold. Most regulatory authorities all around the world require the plan of mines and open-pits closure even before the mining begins, as it must be determined that the site would not pose a threat to the environment or society in future. Depending on the location, the site of mine or open-pit may be used in alternative way after closure or restored to the pre-operational condition. Local authorities increasingly require financial assurance that the funds needed to close mining enterprises will also be available in emergency situations. Special attention is paid to the environmental insurance intended to limit liability related to pollution elimination after mining activities at abandoned fields are over. In close connection with environmental insurance is post-mining – the development of alternative use of mining sites after the closure of mines and open-pits.
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.
