摘　　要：为了充分利用矿产资源,提高储量级别,延长矿井服务年限,对戴坊萤石矿矿体周围成矿有利地层、控矿构造及成矿热液来源进行了技术论证,并结合矿区外围地面踏勘、85 m水平以下井巷工程揭露成果,对戴坊萤石矿成矿地质特征及找矿方向进行了研究。结果表明:矿体周围具有良好的成矿地质条件,动力变质岩的形成在时间上、空间上、成因上均与萤石矿的形成密切相关,断裂破碎带中的动力变质岩是寻找隐伏萤石矿体的良好标志。在上述分析的基础上,将矿区外围划分为3个重点找矿工作区,即85～-80 m水平、矿区外围北部800 m、矿区外围南部1 000 m,供区内后续找矿工作参考。In order to make full use of mineral resource,increase reserves and prolong mine service life,the technical argumentation of favorable strata for mineralization,ore-controlling structures and source of metallogenic hydrothermal is done,based on the ground reconnaissance results of the mining area periphery and the disclosure results of sinking and driving engineering below 85 m level,the metallogenic geological characteristics and prospecting direction of Daifang Fluorite Deposit are studied.The results show that the metallogenic geological conditions around the orebodies is appropriate,the formation of dynamic metamorphic rock is temporally and spatially associated with fluorite ore mineralization,besides that,the genesis of dynamic metamorphic rock is closely related to the formation of fluorite deposit,the dynamic metamorphic rock in fracture zone can be an outstanding prospecting indicator for concealed fluorite orebody.Based on the above discussion results,three key prospecting areas around the mining area are confirmed,which are 85^-80 m area, 800 m in the north and 1 000 m in the south of mining area periphery.
