低频电磁法是一种寻找良导性矿体的普查手段.国外早在四十年代就已广泛采用了,并且得到良好的地质效果.多年来我国科研单位和地质院校为开展此方法,曾研制了多种低频电磁法仪器,由于种种原因都未能得到推广.近二年,我队应用武汉地质学院研制的DDW-1型无参考线虚分量仪,在几个矿区作了试验,取得较好的效果.实践表明:该方法理论比较成熟,仪器轻便灵活,工作效率高,成本低,并有对异常分辨能力强和不受接地条件限制等优点.
Low-frequency electromagnetic method is a kind of census method to find good conductivity ore body, which has already been widely used in foreign countries as early as the 1940s and got good geological effect.For many years, our country’s research institutes and geology colleges have carried out this method. Developed a variety of low-frequency electromagnetic method instruments, due to various reasons have not been promoted.In the past two years, our team using the DDW-1 developed by Wuhan Institute of Geology without reference imaginary component instrument, made a test in several mines to obtain Good results.Practice shows that: This method is relatively mature theory, light and flexible instruments, high work efficiency, low cost, and has strong ability to distinguish anomalies from ground conditions and other advantages.
