【美国能源信息管理局网站2012年5月9日报道】2012年5月9日,美国能源信息管理局(EIA)公布了2011年美国国内铀生产报告。现将该报告内容简要介绍如下:钻孔2011年,美国在铀资源勘探工作中共钻孔5441个,钻孔总长度约为330万英尺。在铀资源开发工作中共钻孔5156个,总长度300万英尺。因此,在铀资源的勘探和开发工作中共钻孔10597个(见图1),比2010年(7209个)增加了47%;总长度为630万英尺(见图2),比2010年(490万英尺)增加了31%。2011年勘探钻孔活动的总支出为5360万美元,比2010年(4460万美元)增加了20%。
[US Energy Information Administration website reported on May 9, 2012] On May 9, 2012, the United States Energy Information Administration (EIA) released the 2011 domestic uranium production report in the United States. The report is summarized as follows: Drilling In 2011, the United States drilled a total of 5441 holes in uranium resources exploration with a total drilling length of about 3.3 million feet. In the development of uranium resources, a total of 5,156 drilling holes, a total length of 3 million feet. As a result, a total of 10,597 holes were drilled in the exploration and development of uranium resources (see Figure 1), an increase of 47% over 2010 (7209 cases); the total length was 6.3 million feet (see Figure 2) Million feet) increased by 31%. The total expenditure on exploration drilling in 2011 was 53.6 million U.S. dollars, up 20% over 2010 (44.6 million U.S. dollars).
