Abstract:A qualified cemented rockfill system has been developed in Xinqiao Pyrite Mine according to the key techniques and parameters of cemented rockfill derived from the model test of large stope. The cemented rockfill technique adopted has strengthened the safety of mining and reduced the fill cost about 4.2～5.0 million Yuan per year. The researching result provides a good example for the similar mines to use the technique.
