| A mircroseismic monitoring system suitable for underground microseismic monitoring based on DSP technology is developed and several important aspect of implementation of this technique are studied in this paper. Seismic wave's property is studied and seismic sensor's selection and setup are discussed at first. Then, several parts are designed include the prep-amplifier , low pass filter data acquisition of the core of system and the serial interface between DSP and PC. Finally,the disquisition presents some measures of anti-interference.
