ARES-5/E - Seismic-acoustic system for rock-burst hazards assessment


Assessement of rock-burst hazards in the longwall area.

The task of the ARES-5/E system is converting the velocity of mechanical vibrations of rock-mass into electrical signals by means of SP-5.28/E
geophones which are fastened on anchors situated in the walls of top and bottom roads. Then the signals are sent to the surface, to the surface mining geophysics station, where they are digitally processed and computerinterpreted.
