Kohtieva O. Ensuring safety in the construction of defence and industrial complexes in disused mines and workings.

The thesis is devoted to ensuring safety during the construction and operation of underground structures in existing coal mine workings, taking into account the risk-based approach to assessing occupational hazards. Recent events in Ukraine dictate new directions and areas of research. Human security is a right guaranteed by the Constitution of Ukraine and other legislative acts and documents. Military operations on the territory of the state prompt even greater attention to safety not only in production, but also in the everyday life of every person. The world has long been interested in underground construction for various reasons. One of them is the safety of human existence during man-made or other events. Underground space and underground construction can be such a safe space. However, in addition to threats of anthropogenic and other nature, it is necessary to be confident in the safe condition during the construction and operation of an underground structure. This paper presents for the first time a methodology of a risk- based approach to monitoring the condition of an underground facility on the example of a workings under a standart scenario of events and in the state of boundary conditions under the influence of dynamic forces from the outside, which is necessary to identify and prevent dangerous situations during the work of employees when reusing workings intended for the placement of military-industrial facilities in them. The terms of use are determined and appropriate recommendations for monitoring and using the underground space are proposed. Together with the Institute of Geotechnical Engineering of the National Academy of Sciences of Ukraine, with the direct participation of the author, methodological recommendations were developed and approved for determining risks and assessing the risk of loss of stability of underground workings intended for the placement of industrial and defence facilities in order to ensure safe operation and safe use of underground space as a defence and industrial facility.
