Abstract: The eastern mining area of Longshou Mine is located in the active area of fault structure development. Previous geological data show that this area has good prospecting prospects. On the basis of summarizing the previous geological work，through structural analysis and dynamic analysis，the late tec⁃ tonic dislocation process and late magmatic activity law are revealed. The location law of the ore body is de⁃ termined，and four“ ore prospecting ”models are constructed. At the same time，the geological and techni⁃ cal work extended to the whole process of production and construction，and the exploration work is carried out in the development project of the eastern mining area of Longshou Mine. New branch rich ore bodies are found in the upper and lower plates of the main ore body，which effectively guides the efficient develop⁃ ment of the subsequent exploration work.

Key words: tectonic analysis, juvenile motion, location law, prospecting
