天然电场选频法在水文地质工作中的应用

Natural electromagnetic field frequency selection is a kind of geophysical exploration method which use earth electromagnetics field as its work field source. This method can find groundwater , basement fracture zone, subterranean cavitation etc. through a handy, quickly and effective way. The method suits for complex landforms, which is more quickly, laborsaving than normal geophysical exploration method, which confirm its widespread applications in engineering geophysical exploration. The authod apllied this method to his hydrogeological work, analyzed the hydrogeological feature in the research area, which provided the foundation for diggings exploitation.
