Design of a data-acquisition system for underground microseismic monitoring based on ADS7852;

Analysis to the field application effect of inner well microseismic monitoring technique;

Application of correlation filter in processing of microseismic data;

Application of Microseismic Monitoring Method in Disaster Prevention of Underground Mine;

Study of Microseismic Monitor System based on Virtual Instrument;

Research on micro seismic monitoring and measurement of overburden strata movement variation law in outcrop seam mining;

Micro seismic phenomenon is an important information before fracturing of rock mass;studies of micro seismic characteristics of the fracturing process of rock mass are of important significance for prediction of fracturing and destabilizing of rock mass and guaranteeing the safety of mine production.

Method of coherent filtering in frequency domain and polarization filtering in time domain for micro-earthquake data;

The paper adopted the technique of micro seismic monitoring.

Four fundamental methods are introduced,namely well temperature,ground potential survey,microearthquake and radioactivity isotope,which were used to monitor the fracture geometry of fractured coalbed methane wells in North China.
