摘　　要：在下向分层采矿过程中 ,利用高水固结充填 ,其接顶效果好 ,充填体凝固时间短 ,早期强度高 ,若通过提高进路回采高度来减少分层个数 ,可节省假底施工费用 。In underhand cut-and-fill mining, high water content consolidation filling is used, which offers excellent fill-roof contact, short consolidation time and high early strength. If drift height is enhanced, the total number of slices can be reduced, this will cut down the cost for construction of artificial bottom structure, thus raise mining productivity and stope capacity.

关 键 词：下向分层回采 高水固结充填 接顶效果 回采工艺 充填工艺 经济效益
