Dunin V. Influence of industrial explosions on durability of constructions of buildings in the conditions of Kryvyi Rih

The aim of the work is experimental and analytical studies of the impact of industrial explosions in the iron ore quarries of Krivoy Rog on the boundaries of their sanitary protection zones, which are located in the immediate vicinity or cover residential areas of the city. In the dissertation, for the first time, new experimental research data on the effect of industrial explosions on the technical condition of buildings and structures on the border of the sanitary zone of the iron ore quarries of OJSC SevGOK, RU GOK Krivorozhstal, OJSC TsGOK and OJSC YuGOK, integral vibration diagnostics. For the first time, a methodology for assessing the life of buildings and structures has been developed, including three parts: (1) experimental studies of the dynamic response of buildings or structures to explosive effects, as well as visual inspection; (2) mathematical modeling of the object under study; (3) systematic integration of research results and their final analysis. The numerical method for processing the results of experimental studies of the response of buildings and structures to seismic effects from industrial explosions has been improved. Participated in the development of two regulatory documents of the Ministry of Regional Development of Ukraine DBN В.1.1-12:2014 "Construction in seismic regions of Ukraine" and DSTU-N B V.1.2-17: 2016 "Guidelines for scientific and technical monitoring of buildings and structures", which were put into effect. Scientific and methodological developments of the dissertation work were introduced at OJSC YUGOK in the study of the influence of industrial explosions on buildings and structures at the border of the sanitary protection zone of the quarry.
