FIELD: mining.
SUBSTANCE: station consists of stationary and external housings. Unit of seismic receivers, analogue amplifiers, low-pass filters, remote digital recorder and correct time unit are arranged in stationary tight housing. Stationary housing is equipped with ballast and installed on the frame. External housing is made in the form of sphere inside which there arranged is central computer, hard disk unit, hydrophone, unit of hydroacoustic communication channel, hydrophysical module, ballast opening connection, timer of opening connection, flashing beacon, radio beacon, external communication connector and power source. External housing is connected to stationary housing by means of cable rope. Stationary and external housings are located from each other at distance of 50-100 m.
EFFECT: improving prediction accuracy of abnormal phenomena; enlarging functional capabilities.
