摘　　要：罗辛铀矿山是目前世界上惟一尚在运营中的侵入体白岗岩型铀矿。近10余年来,全球铀市场不景气、铀生产疲软、铀矿勘查投资乏力。铀的市场价格从20世纪70年代末期的111.8美元/kg U急降至90年代中期的22.1美元/kg U。使用地下常规与露采相结合开发的罗辛铀矿山何以能在不景气的铀市场中持续铀生产的呢?加强矿床、矿物、工艺学研究,降低生产成本,改善铀的营销策略等举措不仅使罗辛铀矿山维持着当前的铀生产,而且还可保证其在未来15 a里的持续发展。勘查低成本的铀矿固然重要,但对已有硬岩铀矿加强地质经济学研究,在矿山开发中采用新技术改造传统旧工艺,开发硬岩铀矿也可像罗辛铀矿山那样,取得明显的成效。Rossing uranium mine is the only operating uranium mine in the world where the uranium occurs in intrusive alaskite. In the past 10 years, uranium market regressed in the world, uranium production weakened, expenditures of capital for uranium exploration were insufficient . Uranium spot market price rapidly decreased from $ 111. 8/kg U in late 1970' s to $ 22. I/kg U in mid-1990' s. Why can Rossing uranium mine mined with traditional underground and open pit operation can keep running even in low price conditions of uranium market? Augumenting research on the deposit, mineral and technology, decreasing production cost and improving selling strategy can not only maintain Rossing s uranium production at present, but also ensure sustainable development in the coming 15 years. Exploration of low-costed uranium deposits is very important. However, obvious economic benefits can be obtained, as Rossing uranium mine does, by augumenting geological-economical research on the known uranium deposits of hard-rock type and by using new techniques to improve the conventional techniques in the uranium mine development.
