摘　　要：碎石水泥浆胶结充填是近年来发展起来的充填新工艺，充填系统采用水泥浆和碎石骨料分别制备和输送方式，在采场进行混合后充填。铜坑锡矿对该充填工艺进行了试验研究，并获成功，有效地解决了该矿无砂料充填的难题，并取得了良好效果。The wasterock cemented filling is a new technology of backfilling having been developed in recent years. As for the filling system, cement matrix and wasterock aggregates are prepared and transported respectively, then mixed in the stope and filled in situ. The experimental study of this filling technology was made and turned out a success in China′s Tongkeng tin mine. Meanwhile, the filling problem on the shortage of tailings/sand in this mine was settled satisfactorily, and good results were obtained.
