摘　　要：音频大地电磁法具有探测深度大、横向分辨率高、设备轻便等特点,被广泛应用于煤田、水文、工程及环境地质勘查中。近年来在地浸砂岩型、火山岩型和花岗岩型铀矿探测中,为解决沉积盆地盖层中砂岩层(砂体)的空间分布、厚度和埋深,大致查明火山岩、花岗(斑)岩的分布范围及空间展布,推断盆地基底的起伏形态、埋深,推断断裂构造的展布、规模及特征等铀成矿地质环境方面发挥了重要作用,为铀矿地质勘查工程布置提供了科学依据。Audio magnetotelluric method has lateral resolution and portable equipments, the characteristics of large detecting depth, high in therefore has been widely used in coal, hydrology, engineering and environmental geology exploration. In recent years, in the exploration of leachable sandstone type, volcano rock type and granite type uranium deposit exploration, audio magnetotelluric method has played an important role in solving the problem of spatial distribution, thickness and buried depth of the sedimentary basin cover layer sand （sand body）, roughly determining the spatial distribution and thickness of volcano rocks and granitic porphyry, inferring basement topography, depth, scale and the feature of inference, fracture structure, which provides a scientific basis for the arrangement of exploration engineering.
