英文摘要	Abstract To deal with the impact of the typical microseismic (MS) location (TMSL) method with the velocity measurement error on location accuracy, a new location method without pre-measuring wave velocity based on particle swarm optimization (PSO), named the TM-PSO method, is proposed. Then, based on the arrival time of the MS source, combining the sensor array and the expression of the TM-PSO method, the convergence and correlation of objective functions of the TM-PSO method are analyzed theoretically. The field test of the Beiminghe iron mine in Hebei province and the headrace tunnel in the Neelum-Jhelum hydroelectric station in Pakistan show that the TM-PSO method has great location effect and stability, which has important practical application value.
