摘　　要：为查明邹家山矿床4号带深部铀成矿特征,在系统收集资料基础上,利用Surpac软件构建矿体三维模型,开展探采对比研究。结果表明,铀成矿位置对岩性没有选择性,鹅湖岭组碎斑熔岩的底部、打鼓顶组流纹英安岩的上部以及组间界面均有矿体发育。邹家山矿床成矿构造为北东向和北西向,其中-130 m以上矿体受北东向邹家山-石洞断裂控制,矿体整体呈北东向;-130 m以下矿体以北西向为主,其次为北东向、南北向,矿体受北西向、北东向构造联合控制,且两者连通的情况对成矿更加有利。深部铀矿体赋存在组间界面附近,组间界面滑塌部位与邹家山-石洞断裂构造复合部位是深部铀矿的重要富集场所。In order to find out the deep uranium mineralization characteristics of No.4 zone of Zoujiashan deposit,based on the systematic collection of previous data,Surpac software was used to build a three-dimensional model of orebody and carry out exploration and mining comparative study.The results show that the uranium mineralization location is not selective to lithology,and there are ore bodies in the bottom of the porphyritic lava of the Ehuling Formation,the upper part of the rhyolite dacite of the Daguding Formation and the intergroup interface.The ore-forming structures of Zoujiashan deposit are NE and NW direction,and the ore body above-130 m is controlled by the Zoujiashan-Shidong fault of NE direction,and the whole ore body is NE direction.The ore body below-130 m is mainly NW-trending,followed by NE-trending and SN-trending.The ore body is jointly controlled by NW-trending and NE-trending structures,and the connected NW-and NE-trending structure are more favorable for mineralization.The deep uranium deposits occur near the intergroup interface,especially the collapse site of intergroup interface and the composite site of Zoujiashan-Shidong fault are the important enrichment sites of deep uranium deposits.
