Taoshan is an important location of granitic type of uranium orefield in our country，with abundant uranium resources. But it is diseconomy with the routine mining since the uranium ore bodies show small in size and vein or swarm veinlike in shape with low grading according to the existing data. In this paper, a boldness conceiving of searching buried rich and big uranium ore and its prospecting direction in Taoshan area is put forward from the gained geological exploration achievements combining with the up to date metallogenetic theories, such as deep source metallogenesis, small rock mass metallogenesis and stretch structure metallogenesis.
