岩石破裂时产生电磁脉冲的观测与研究
ELECTROMAGNETIC RADIATION GENERATED BY THE ROCK RUPTURE DURING AN UNDERGROUND EXPLOSION
-
摘要: 在大型的人工地下爆破试验中,距爆点960m处,记录到三组电磁脉冲信号,其中伴随地表岩石破裂时电磁脉冲的主能谱约为200Hz,与我们在隋县观测的结果相近.Abstract: Thr.ee groups of electromagnetic pulses were recorded 960 m away from the point of explosion. The principal power-spectrum is about 200 Hz, which corresponds to the rupture of the surface rock of the earth. This is similar to that observed at Suixian (in Hubei province).
