To ensure the safety of mine production，improve the level of resource utilization and extend the service life of the tailings pond,a full tailing cemented filling system is designed and constructed. Since the system has been put into use for many years，the filling capacity, slurry concentration and filling body strength meet the design requirements，the filling capacity, slurry concentration and filling body strength meet the design requirements, the technological specifications are stable. The successful application of the full tailings cemented filling system in Xitieshan lead-zinc mine has provided key technical support for the safe production of Xitieshan lead-zinc mine, and it has also provided benefits for the green, safe, efficient and economic mining of similar large-scale nonferrous mines in China.
