Treatment of mined-out areas and stoping practice for residual ors in upper and lower walls in Sandaowanzhi gold mine

Residual ore recovery is an effective way to make full use of mineral resources and to prolong mine life.With ores left in mined-out areas as well as on upper and lower walls after stoping high-grade gold ores in Sandaowanzhi deposit,the paper introduces the technique of backfill in mined-out areas and stoping of residual ores in upper and lower walls.Treatment of mined-out areas and stoping of residual ores not only eliminate potential safety hazard but also improve the efficiency of resource utilization,as a result of which more economic profits are achieved.
