摘　　要：针对某金矿原采矿方法损失贫化大的难题，研究推荐机械化上向水平分层全尾砂胶结充填采矿法盘区回采工艺，在试验盘区生产时，180～194m矿体采用“一”字形同步回采，盘区稳定性良好，采场生产能力为150t／d，并节约采准工程257m；194m以上矿体采用“品”字形回采，中间采场超前相邻采场5个分层，采场生产能力为100t／d，取得高效、低贫损的良好效果。According to the high loss and dilution of original mining method in a gold mine, mechanize upward horizontal slice stoping and cemented backfilling with whole tailings was proposed to stope the panel. During the mining in the tested panel, 180-194 m ore body was mined with ＂-＂ glyph panel mining sequence, which achieved good panel stope stability and production capacity of 150 t/d, as well as saved 257 m of mining quasi engineering. The orebody above 194 m was mined using ＂8＂ glyph panel mining sequence, and the middle stope was ahead of the neighboring five slices. Finally, panel production capacity reached 100 t/d with high efficiency, low loss and low dilution.
