To enhance the positioning accuracy of seismic source in underground mining and solve the problem of spatiotemporal changes in the wave velocity field caused by excavation disturbance and complex structures, seismic source relocation with real-time inversion of wave velocity field as a prior was proposed, which combined ray tracing and quasi-Newton iteration algorithm to realize dynamic update of wave velocity field and high-precision positioning of seismic source. The validity of this method was verified by synthetic monitoring and field testing. The synthetic monitoring results showed that compared to the least squares procedure, the real-time inversion resulted in the average positioning accuracy enhanced by 49.8% and the accuracy of wave velocity inversion exceeding 95%. In the field testing, a 180 m×180 m to-be-filled area in mining operation was taken for imaging target. Compared to the least squares procedure, this method brought the average error in positioning reduced by 7.074 m, and the accuracy of wave velocity inversion in each region exceeding 95%. The research indicates that this method not only is suitable for seismic source positioning in microseismic monitoring, but also can be used as a geophysical method for detecting passive imaging of goaf areas.
