Abstract: Paste filling technology is one of currently the most advanced and difficult technology. Since the end of the 80s and the mid 90s， Jinchuan mine introduced ， filling system constructed and studied of the industrial application. Because the paste backfilling technology is the first time applied in in our country， then there are many problems in the design and engineering application. So that the paste filling system had remained non-normalproduction status for six years since had been used in production. Although research work was conducted continuously and technological transformation was carried out，the problems had not been sloved. Based on the engineering experience that had obtained in preliminary work， research of paste filling technology and system transformation were implemented from 2005 to 2006 and the significant development was obtained. The reforming stytem can regular production and the filling production capacity increases year by year from 2006. The filling amount in 2011 was 200000 m³ which is up to the design production capacity of the paste filling stytem. This paper first introduces briefly the application status of the paste filling technology in our country，then generalizes the research progress and achievement of the tailling paste filling technology in Jinchuan mine. Findly， the development tendency of filling mining in Jinchuan mine.the development trend of filling mining is discussed.
