摘　　要：甚低频电磁法是一种轻便快速的方法。在1:50000水文地质调查中,结合航片解译,用该方法查明区域构造分布,作为水文地质调查的前期工作是有效的。在基岩裂隙水勘探中,采用详细的甚低频测量,加上少量的激电测深,可提供裂隙密集带位置、产状,并进行含水性分析,为布钻打井提供有用信息。Abstract The extremely low-frequency electromagnetic method is a rapid techni que requiring only portable devices. In 1:50,000 hydrogeological survey, this method, in combination with the aerophoto interpretation, has proved to be effective in investigating regional structures at the early stage of hydrogeolo gical survey. In the exploration of fissure water in bedrock, the adoption of detailed extremely low-frequency survey, together with some IP sounding work, can reveal locality and attitude of the fissurecrowded zone and conduct water abundance analysis, thus providing valuable information for drilling.
