Abstract: According to the basic algorithm of source location，a Matlabbased positioning procedure of the source was establishedThe Microseismic monitoring data of practical projects were used for source positioningThe 3D groups of the location were displayedThe positioning results and the actual source location are compared with the results by Siroseis software to verify the practicality of the procedureThe microseismic monitoring technology and its research status were researchedThe arrival time of P wave was the main parameter to discuss the microseismic waveformThe way of data optimization grouping and its impact on the positioning accuracy were discussedThe microseism location algorithm and its process and outcome of the realization were introduced in detail，and the reason of the location error was described.
