摘　　要：选取乌鲁木齐遥测地震台记录的部分天然地震与新疆工业化爆破项目中的部分爆破资料,通过波形振幅比AS/AP以及记录在P波垂直向的初动符号的对比,总结出了识别爆破与地震的依据。工业化爆破振幅比的比值比较稳定,且小于天然地震振幅的比值,而天然地震受多种因素的影响,振幅比的比值变化范围大。工业化爆破波形记录的初动向上为"+",而天然地震产生的地震波的初动符号具有四象限分布的明显规律。Choosing the earthquakes from Urumqi telemetry seismic network and explosions datum from the industrial explosions in Xinjiang, we summarized the different features between explosion and earthquake by contrasting their amplitude ratio and first motion of P wave in vertical direction. The amplitude ratio values of explosions are stable, and less than the value of earthquakes; While the range of amplitude ratio values of earthquakes is large, because they are effected by many factors. The first motion of explosions are all up, While the earthquakes are distributed in 4 quadrants.
