Microseismic Monitoring Technique (for short MS）It is a new cross-disciplinary and cross-industry technology developed from seismic exploration industry in recent years. Mainly used in coal mines, metal mines, highway tunnels, oil depots, rock slopes and other safety areas. The microseismic monitoring technology is to use microseismic sensors to monitor the vibration caused by rock mass rupture or other objects, receive the data through the microseismic monitoring sub-station, and process the data by the ground data processing server. The location, magnitude, energy, seismic moment, inelastic deformation and focal mechanism of rock mass microfracture are obtained. Then the stress-strain state of surrounding rock is analyzed in combination with seismological principle, and the purpose of monitoring and warning of coal and rock mass stability is achieved.
