摘要
通过对云南个旧驼峰山锡矿区地表与坑下开展相对应的大地电磁测深勘查试验,从获得的大地电磁测深之标量(TM)和张量(TE)极化模式对比,得出其坑下物探观测到的电性变化信息与地表物探观测到的电性变化信息具有很大的相似性,从而表明坑下大地电磁测深物探方法在矿山深部找矿,具有很好的应用前景,能降低找矿风险,提高找矿效率。
In the corresponding experiment of magnetotelluric sounding exploration of surface and tunnel of Tuofengshan Sn orefield in Gej iu, Yunnan, according to the polarization model comparison of transverse magneticwave inversion (TM) and transverse electric wave inversion (TE),we have achieved the serious similarity of e-lectric variation information in the tunnel to that on the surface, which shows the magnetotelluric sounding in the tunnel has very good application potentiality in the mine deep prospecting, decrease in prospecting risk and in-crease in prospecting efficiency.
