摘　　要：文章是以伊犁、东胜、二连、相山、诸广南部5个一类铀矿大基地为研究对象,开展多学科、多技术方法联合攻关和综合研究成果的展现,建立了建造间古河道型铀成矿模式,深化了“叠合复成因铀成矿理论”,创建了相山火山岩型铀矿5种类型矿体空间定位样式,丰富发展了铀成矿理论;突破了深部有利成矿砂体识别技术,实现了砂岩型铀矿1000 m以浅成矿环境探测;优化发展了火山岩型铀矿深部有利成矿空间识别和花岗岩型铀矿成矿构造识别技术,实现了热液型铀矿1500 m以浅成矿环境探测;构建了5个一类铀矿大基地预测评价系统,预测了成矿远景区224片,预测潜在资源量近75万t,实现了5大基地新层位、新区域、新深度铀资源找矿的突破。The research team focused on five uranium mining bases that including Yili,Dongsheng,Erlian,Xiangshan,and southern Zhuguang,carried out multidisciplinary,multi-technical,and comprehensively research,and established the paleochannel type uranium metallogenic model,improved the“superimposed polygenetic uranium metallogenic theory”,constructed five spatial patterns of Xiangshan volcanic type uranium district,and enriched the uranium metallogenic theory.In addition,the research team has optimized the recognition technology of deep favorable metallogenic sand bodies of sandstone type uranium deposit,realized the epi-metallogenic environment detection of sandstone type uranium deposits that are shallower than 1000 m,developed the deep favorable metallogenic space and uranium metallogenic structures of volcanic and granite type uranium deposits,and realized the exploration technology of metallogenic environment of hydrothermal type uranium deposit less than 1500 m,which has significantly enhanced the exploration ability.The research team has constructed the prediction and evaluation systems for the five large-scale uranium mining bases of class I,proposed 228 prospecting areas,with a predicted resource amount of nearly 750000 tons,and made a breakthrough in new exploration horizons,new exploration areas and new exploration depth of uranium resources in five bases.
