Abstract: Microseismic Source location software is mainly based on the TDOA location algorithm using P -wave or S-wave travel time measured by detectorThe polarization analysis is often used to the seismic waveform noise eliminating measured by detectorIn fact，the microseismic source can be determined according to the three-component of p-wave vibration in the space stationOnly the direction of one ray can be obtained from station sites to the position of source，according to the principle of the same direction of vibration and propagation of p-wave to determine the space location of the station sites from the vibration sourceIt is clear that the intersection in all directions-ray position is the focal pointIn Combination of the advantages of Matlab software in the matrix calculation，polarization analysis can reflect the advantages of the calculation speed and positioning accuracy with relatively strong practical applicationAccording to the simulation algorithm，the polarization analysis method can be used to locate the position of micro-seismic events within the range of accuracy，thus providing another research direction for the positioning method
