Wuyi, Yongkang, Dongyang and other counties are main fluorine producing region in Zhejing province or all over our country. Because of thinking little of management in mining, land subsidence and other geologic calamities have been happened frequently in producing or ceased mines, and they have become the best grievous and potential geologic calamity. This paper introduces the methods and effect for using the high density resistivity method to prospecting exhausted area of Heyetang Fluorite Mine in Wuyi county; suggests that this method can be used for necessary means in prospecting of exhausted area; and points out that the α-system and α 2- system are best systems, A-M-system and other systems can also be used for selective or cooperated with others.
