镇江铁矿地下爆破振动测试分析

Observation and Analysis of the Explosion Earthquake at Weigang Underground Iron Mine

通过对镇江韦岗铁矿地下爆破振动速度测定 ,探索了质点峰值振速衰减规律 ,研究了振动频率、纵波速度和振动持续时间 ,并作了频谱分析。

By observing and detecting the explosion vibration velocity at Weigang Iron mine in Zhengjiang city, the damping laws of the particle peak velocity, the vibration frequency, the longitudinal propagation and its duration have been presented. Applying the explosion earthquake wave measurements, the frequency spectrum has been also analyzed.
