摘要
为了实现对大庆遥测地震台网网内事件的精确定位，分析了台网的实际情况，建立了网内Ｐ波速度模型，并根据该模型编制出相应的初至Ｐ波走时表。采用初至Ｐ波定位方法，取得了很好的结果。３次爆破实验表明，在炮检距均大于１０ｋｍ的情况下，最小定位误差仅５７．７ｍ。
In order to exactly locate microseismic events observed in the area Daqing Telemetered Seismic Network,we analysed the real situation of the network,set up a Pwave speedmodel,and calculated the corresponding travel time table by on the basis of the model.Using the locating method of the preliminary Pwave,we have gained good results.Three explosion tests,which the distance between the points of explosion and the points of determinations are over 10 km,indicated that the smallest location error is only 577 meters.
