Chen Zongtuan; Zhang Jilin; Xu Maizhi (Institute of Marine Geology,Qingdao,266071)  
After a brief review of the history of exploration and research of deep-sea solid mineral resources milning,the authors discuss the prospect from several aspects:the status and problems of exploration and metallurgy,environmental and social problems in deep sea mining and the relatioliship between international laws and deep-sea mining.The authors hold that the exploration methods and mining and metallurgic technology are mature enough for the deep-sea mining today.Technologically speaking,the commercial mining would come true within about 30 years. However, in consideration of international laws, environmental poltltion and national relationship, the commercial mining would perhaps come true by themiddle of next century.
