1991年在魁北克省Rouyn-Noranda地区的Mobrun矿上曾完成了一次用地震电法勘测块状硫化物矿的地下试验。该法的基本原理是地震能量在通过硫化物矿时转化为高频电磁脉冲辐射。放炮激发与电磁辐射之间的延迟为声波到达地震电法转换带间的单程旅行时,因此,如果将其与P波速度结合起来,便能计算出炮点到矿层的距离。50米的矿体内装入 In 1991, an underground test of electrical seismic surveying of massive sulphide ore was completed at the Mobrun mine in Rouyn-Noranda, Quebec. The basic principle of the law is that seismic energy is converted into high-frequency electromagnetic pulse radiation when passing through sulphide ore. The delay between firing excitation and electromagnetic radiation is the one-way travel between the acoustic wave arrival at the Seismic Electro-Mechanical Transformation Zone, so the distance from the shot to the mine can be calculated if combined with the P-wave velocity. 50 meters of ore body into
