Abstract: In order to explore the technical conditions for the development of dolomite and limestone deposits for flux in Kejia Village，Dongzhi County，the geological background，deposit characteristics and ore types of the mining area were analyzed. The results show that the dolomite and limestone deposits in this area are stable along the strike and dip，with simple internal structure and excellent ore quality. It is the production place of dolomite and limestone for high-quality flux. The mining area has good prospect re⁃ source potential，and the research results provide reference for subsequent prospecting work in the area.
