Development of Methods to Improve Stability of Underground Structures Operation

Sustainable development is an integral part of the modern world. However, sustainable development is impossible without rational, environmentally and economically efficient use of resources. In the process of construction and operation of underground structures (mines, subway stations, subway parking lots, etc.) there are many factors that cannot be taken into account at the design stage. These factors have a negative impact on the durability of use, economic profitability of operation, etc. In this paper, the authors used the theory of system analysis to form and optimize the factors affecting underground structures. They identify the relevant regularities and interrelationships. They determine the list of the most important factors based on the peculiarities of a particular object of study. They build a conceptual and then a mathematical model. In the practical part of the study, the authors model the temperature field formed in a horizontal mine. They compared the obtained results with the modeling results presented by others and showed the effectiveness of the proposed methodology. A distinctive feature of this work is the proposed methodology for assessing the factors affecting sustainable development. This methodology is universal and can be applied to assess the sustainable development of any management object.
