电法勘探是利用岩石、矿石的电学性质(或称“电参数”)的差异,来調查地下地质情况和寻找有用矿产的一种物探方法。电法勘探包括的具体方法最多,現有并在生产中应用了的电法,如果詳細加以划分,就有四十多种。因为岩石、矿物的电学性质包括許多方面(导电性、电化学活动性、电极化特性、介电性等等), Electro-prospecting is a geophysical method that uses the difference of electrical properties (or “electrical parameters”) of rocks and ores to investigate underground geological conditions and find useful minerals. There are more than 40 kinds of electric methods that include the most specific methods and the existing ones that are used in production. Because of rock, the electrical properties of minerals include many aspects (electrical conductivity, electrochemical activity, electrical polarization, dielectric properties, etc.)
