摘要

The proposed method for the seismic and acoustic investigation of geologic abnormalities in mine workings consists in exciting seismic sounding signal in the mine working, receiving the sounding signal in the opposite working, at least at two points that are spaced from each other by the distance of no less that one fourth part of the distance between the mine workings, determining the ratio between the values of the high-frequency components of the gain-frequency characteristics in the frequency range that includes at least one third part of the whole signal frequency spectrum. The geologic abnormality is detected If the said ratio exceeds the value of the gain-frequency characteristic of background signal by a factor more than two.
