MONITORING OF THE INFRASOUND BACKGROUND LEVEL IN GUBKIN, BELGOROD REGION

Abstract

Instrumental observations of the level of the infrasound background in the frequency band of 1–20 Hz from working equipment during the export of ore from the Lebedinsky and Stoilensky quarries are described. More than 130 units of basic mining equipment operate in the quarries every day, which are a source of intense infrasound vibrations. The measurements were carried out between June and October 2022 and 2023. The conducted studies have shown that an increase in the number of mass explosions in 2023 and, as a result, the intensification of ore export, led to an increase in the infrasound background by 4–9 dB compared to 2022. However, its value does not exceed the maximum permissible levels for residential areas of 75–90 dB.
