摘要
铀资源是重要的战略物资,也是核能发展的重要保障,被称为"军工基石、核电粮仓"。砂岩型铀矿目前已成为国际上主要开采的矿床类型,也是我国铀资源的主要类型。二连盆地砂岩型铀矿与煤在空间上具有一定的成生联系。论文通过二连盆地准达赖地区煤田勘查钻孔资料的筛选,进行二次开发,对自然伽玛异常钻孔进行钻探查证,取得较好的找矿成果,分析了煤田钻孔与验证钻孔吻合度、煤田钻孔放射性与验证钻孔铀品位相关性等问题,为该区后续开展砂岩型铀矿找矿工作提供了重要依据,同时为其他煤田勘查区开展砂岩型铀矿调查工作部署提供了参考和范例。
Uranium resource is an important strategic material and an important guarantee for the development of nuclear energy. It is called " the cornerstone of military industry and the granary of nuclear power". Sandstone type uranium deposits have become the main type of uranium deposits in the world and also the main type of uranium resources in China. The sandstone type uranium deposits in Erlian Basin are related to coal in space. In this paper,through the screening of the drilling data of the exploration of the coal field in the quasi Dalai area of Erlian Basin,the secondary development is carried out,and the drilling verification of the natural gamma abnormal drilling is carried out,and good prospecting results are obtained. The problems such as the coincidence between the drilling and the verification drilling,the correlation between the radioactivity of the drilling and the uranium grade of the verification drilling are analyzed,which provides a heavy basis for the subsequent exploration of sandstone type uranium deposits in this area It also provides a reference and example for other coal exploration areas to carry out the investigation of sandstone type uranium deposits.
