摘 要:铀是重要的能源矿产和战略资源,在成熟市场经济国家里,能源矿产勘查属商业性矿产勘查活动。铀勘查活动风险大、回报高,成熟市场经济国家用法规、纳税、环保等规则规范铀勘查活动。中国今后也将把煤炭、油气、铀、油页岩、煤层气等能源矿产放在商业性矿产勘查的首位,了解成熟市场经济国家铀勘查活动的现状十分必要。Uranium is an important energy mineral and strategic resources. In countries of completed market economy, energy mineral exploration belongs to commercial mineral exploration. Because uranium exploration is higher in investment risk and rebound, the countries of completed market economy regulate uranium exploration by using laws, paying taxes and protecting environment. China will put the exploration of coal, oil and gas, uranium, oil shale, gas in coalbed in the first place in commercial mineral exploration. Therefore, it is quite necessary to understand uranium exploration industries in countries of completed market economy.
