摘　　要：叙述了山西大同数字遥测地震台网的结构及监测能力、台网的功能及技术指标和遥测台技术系统、供电系统、中心系统、避雷系统、中继站、信道等的建设情况 ,分析了山西大同数字遥测地震台网考核运行期间获得的资料 ,结果表明 ,大同数字遥测地震台网在检测地震能力、动态范围、地震处理精度和速度方面优于模拟台网 ,对网内大部分区域及东部网缘区域的地震监控能力可达 1 .5级 ,网内地震响应速度小于 1 0 min。得出该台网可为地学研究及地震预报提供更为丰富的数字地震资料的结论。The structure, seismic monitoring capacity, functions and technical features of network as well as the technical system of station, power supply system, central control system, lightning proof system, relay station and communication channel are introduced. The data from the Telemetric the Digital Seismic Observatory System of Datong of Shanxi Province in the test period are analysed. The results show that the seismic monitoring capacity, dynamic range, and earthquake locating speed of the Telemetric the Digital Seismic Observatory System of Datong of Shanxi Province are superior to the analog seismic network. The minimum earthquakes that can be detected in the most region within the network and around its eastern edge is [WT6BX]M[WT6BZ]=1 5. The time needed for the earthquake location is usually less than 10 minutes. The completion of this network will provide more useful digital seismic data for seismological study and earthquake prediction.
