铀矿开采是一个相当年轻的采矿部门,近20年来发生了明显变化。目前各矿开采的矿石,含铀量波动范围很大,介于0.03％(贫矿床)～6.0％(加拿大新近开发的富矿床)。计划建设的矿山,矿石含铀量有的高达10％以上。近些年来,铀的需要量减少,加拿大和澳大利亚发现了富铀矿床并相继投产,美元兑换率不断下降,一些国家对建设核电站作了政策性的限制,这些都使铀矿开采的结构起了很大变化。
Uranium mining is a fairly young mining sector, with noticeable changes in the last two decades. At present, the ore mined in various mines has a wide range of uranium content, ranging from 0.03% (lean deposit) to 6.0% (recently developed rich ore deposit in Canada). Plans to build mines, ore containing uranium as high as 10% or more. In recent years, the demand for uranium has been reduced, the enriched uranium deposits have been discovered in Canada and Australia and put into operation one after another, and the U.S. dollar exchange rate has been declining. Some countries have made policy restrictions on the construction of nuclear power plants, which have led to the structure of uranium mining Great changes.
