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 realize the accurate positioning of the events in Daqing telemetric seismic network, the paper analyzes the actual situation of the network and establishes the intra-network P-wave velocity model and compiles the corresponding first-arrival P-wave travel timetable according to the model. Using the first P wave positioning method, and achieved good results. Three blasting experiments show that the minimum positioning error is only 57.7m when the offset distance is more than 10km.
