Jinchuan Nickel Mine is one of the large copper sulfide nickel deposit in world. Because the buried depth of the ore is larger，the ground stress is higher and the stability of the ore and rock masses is poorer，it is one of the most difficult deposits to mining in the world. According to the mining technical conditions of Jinchuan deposit，a lot of researches have been carried out since the mine was built. At first，this paper provides a brief overview on engineering general situation of Jinchuan mine，then summarizes the filling mining development in Jinchuan mine. On this basis，it further expounds the research results of filling technology obtained in Jinchuan mine. Based on a large number of research on engineering geology and mining method test，the downward layered cemented filling mining method was used. Research development on filling mechanism，multipurpose use of solid waste，filling slurry rheological properties and pipe reduction conveying etc. had been obtained. Especially the paste filling technology that was the first time to be used in our country，was studied and filling system was reformed， the paste filling had reached design production capacity smoothly. Finally it points out the current situation and existing main problems in filling mine and puts forward key technical problems to solve in order to realize the safe，efficient，economic and environmental mining in Jinchuan Nickel Mine.
