Abstract：The characteristics of the linear location and the Geiger¢s location method are analyzed；and a new location method by combining the two location methods is given. With the multi-channel digital microseismic monitoring system in Shizhuyuan mine，the blasting with three location methods is proposed；and the results by making a blasting test at the assigned location are compared. Some conclusions are drawn as follows：the combination of the linear location and the Geiger¢s location method can solve the problem of low accuracy for the linear location；and the choice of initial value for the conventional Geiger¢s location method can be optimized. In addition，the efficiency of the iterative solution can be improved；and the singular result with an inaccurate initial location value when singular matrix happens in the locating process with the Geiger¢s method can be achieved.
