高频电磁波法在低吸收剖面上探测良导电金属矿,已有不少成功的例子。但是有效地用于高吸收剖面勘查导电性差的小矿体,在我国这是第一次。本文介绍部分成果。这是地质部物探所和武汉地质学院物探系共同协作,从77年开始在新疆某铬矿区所做的试验工作。该矿区的低导电铬矿(井下直流电阻率大于500欧姆·米)产在高导电(井下直流电阻率值小于50欧
High-frequency electromagnetic wave method in the low absorption profile to detect good conductive metal ore, there have been many successful examples. However, it is the first time in our country to effectively use the small ore body with poor conductivity for high-profile survey. This article describes some of the results. This is the Geophysical Institute of Geology and geophysics of Wuhan Institute of Geology work together to start from 77 in a chromium ore in Xinjiang to do the test work. The mine’s low conductivity chromium ore (downhole DC resistivity greater than 500 ohm · m) produced in high conductivity (downhole DC resistivity of less than 50 Europe
