Abstract: The rapidly development economy demands a great deal of mineral resources while some medium and large-sized mines are facing the drying-up challenges. And an increasing number of them will have to shut up, making China more and more dependent on mining resources import. Thus it is critical for them to seek replacement resources.This paper deals with the problems concerning the exploration and exploitation, studying the positive sides and feasibilities of replace-ment resources for crisis mines. The solutions include making use of the fundemental documents, applying new theories and techniques, searching new deposits and new minerals, and the comprehensive use of the resources.
