摘要
对南芬露天铁矿生产爆破产生的地震波进行现场测试 ,获得了大量有效的人工爆破震动数据。通过对这些数据的时域和频域分析 ,研究了人工爆破地震的振动速度、频带、主振频率和衰减时间等参量的变化规律 。
A great number of effective artificial blasting-caused vibration data were obtained through the on-site testing of the seismic waves caused by the production blasting at Nanfen Iron Open-pit Mine. Based on the analysis of time domain and frequency domain of the test data, the change laws of the parameters of man-made blasting-caused seism such as the vibration speed, frequency bandwidth, dominant frequency and dying-away time were studied. The effect of man-made blasting on underground tunnel was also analyzed.
