铀矿地质勘查
中国铀矿地质勘查工作始于 20世纪 50年代，至今已累计投入钻探工作量 4000多万米，完成了近 1/3国土面积的高精度航空放射性调查，查明 370余个铀矿床。在新一轮全国铀矿资源潜力评价中，预测铀矿资源潜力超过 280万吨，显示出巨大的找矿潜力。 20世纪 90年代中期以来，中国铀矿找矿重点转向砂岩型铀矿，并在北方沉积盆地取得了重要突破，实现了新增铀矿资源储量翻番。伊犁、鄂尔多斯、二连、松辽、吐哈、巴音戈壁等盆地探明了一批大型、特大型铀矿床，其中鄂尔多斯盆地东北部已成为中国首个十万吨级铀矿资源大基地。目前，中国 23个省（区）发现有铀矿资源，以内蒙古、江西和新疆铀资源最为丰富。
Uranium Exploration
Uranium exploration in China started in the 1950s. The total drilling completed thus far amounts to more than 40 million meters. High-precision aerial radiological surveys of nearly 1/3 of the country’s land area have been completed, and more than 370 uranium deposits identified. The latest evaluation of potential uranium resources across the country predicts a total of more than 2.8 million tons of uranium. Since the mid-1990s, the prospecting for uranium has shifted to sandstone-type uranium deposits and important discoveries have been made in sedimentary basins in northern China, doubling the identified reserves of uranium resources. A number of large or extra-large uranium deposits have been found in Yili, Ordos, Erlian, Songliao, Turpan-Hami and Bayingebi basins. The northeastern part of Ordos Basin is found to be home to China’s first known 100,000-ton uranium deposit. Uranium resources have been discovered in 23 provinces (autonomous regions) in China, of which the Inner Mongolia Autonomous Region, Jiangxi Province and Xinjiang Uyghur Autonomous Region have the most abundant deposits.
