A tungsten mine uses breast stoping method,leaving a large amount of pillar resources that are difficult to recover.In light of that,the paper proposed mining environment reengineering technology to recover point pillar.Based on the occurrence status of point pillar in goafs,the ore blocks are pided,retaining walls are constructed at the bottom structure and ore block boundary to fill the goaf as a whole and change the stress status of the goaf.When the curing period of the filling body is due,the filling body is first excavated from the bottom pillar position.If the ore pillar is encountered,the excavation still conforms to the standards of cut uphill until the cut uphill is through with the upper middle section roadway and the ore pillars yet to recover are recovered by wall brushing in retreat ways.The technology has achieved good effect of ore pillar recovery.
