Abstract:
Purpose. To decrease influence of occurrences of ecological hazards formed by induced earthquakes in an industrial region on the man and environment.
Methodology. Determination of the rate of displacement of soil or structural elements during induced earthquakes is based on multichannel recording of short-term processes occurring in geological environment followed by the analysis of amplitude-frequency parameters. For instrumental measurements, the vibrating graph I-00-2, the magnetographer NO-68, the seismic sensors SM-3, СВ-20, АТP-1М were used. The calibration of the seismic channel was carried out dynamically on the vibration stand VUT-300/6. Consequences of manifestations of environmental hazards were determined by visual observation and determination of geometrical parameters of damage, as well as medical control and population surveys.
Findings. Based on the system analysis the structure of the monitoring system of distress during induced earthquakes was considered, which includes detection of sources, instrumental measurements of parameters of their influence on objects, detection of defects, public opinion poll. According to the results of instrumental measurements of the rate of displacement of soil and elements of constructions of buildings in the event of induced earthquakes of various origins, their impact on the state of ecological security in the Kremenchuk industrial region is determined. Mechanical damages to residential and industrial building structures and temporal health disorders of inhabitants were detected. Explosions at careers and transport highways as sources of induced earthquakes were studied. Exceeding of possible level of vibrations is fixed in residential and industrial building, located in the zones affected by these sources. A system of technical solutions as for decreasing influence of ecological hazards is offered. In particular, artificial change of parameters of environment is foreseen in direction of passing of mechanical waves to objects of the different purpose.
Originality. Scientific principles of improving the states of ecological safety at influence of induced earthquakes got their further development by working out the system of technical measures as a result of the ecological monitoring, in particular, change of parameters of environment between the source of danger and object which it influences on.
Practical value. The use of research results will help to ensure the constructive integrity of buildings of different purposes and comfortable living conditions of the population.
