| Abstract: | In view of the problem in the existed uncemented backfill system with classified tailings in Lingnan gold mine,a technical transformation has been conducted adopting a technique of a cemented backfill with whole sand tailings flow with backfill parameters as follows: the concentration of tailings for backfill is 69%±1%, flow rate is at 180 m3/h and an annual capacity of backfill is at 700 000 m3, which resulted in no bleeding occurred in the tailings pulp for stope backfill. Such technical transformation has not only improved mining environment and safety conditions, but also greatly increased the resources recovery. |
