【摘要】 利用南丹大厂矿区地震监测台网的数字波形记录资料,采用波形对比方法,分析大厂矿区人工爆破与天然地震波形特征。分析结果表明,爆破与地震在P波平均周期具有不同的特征,可为今后区分该大厂矿区爆破与天然地震提供判定判据。。更多还原

【Abstract】 By using comparison method of waveform, with digital waveform recordings of seismic monitoring network of the Dachang mining area in Nandan, the paper analyzes the characteristics of waveform of its artificial blasting and natural seismic. The results show that that the blasting and the earthquake has different characteristics in some aspects, such as symbol distribution of P-wave first moving,the average period of the Pwave and so on, to distinguish with accurate criterion between the region bursting and natural earthquakes.更多还原
