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.
