摘　　要：倾斜薄—中厚矿体的开采是矿山面临的难题之一。通过调查河西金矿地质条件及岩体质量分级,判定矿岩为中等稳固。依据矿体形态、矿岩稳固程度,进行采矿方法优选。确定采用机械化上向水平分层尾砂胶结充填法,并进行矿块布置以及采切、回采、充填等工艺设计。实践表明,河西金矿采用机械化上向水平分层尾砂胶结充填法,采场矿石生产能力达180 t/d,损失率8.00%,贫化率10.00%,作业安全性和工作效率得到提升。The mining of inclined thin-medium thick ore bodies is one of the difficulties faced by mines.By investigating the geological conditions and rock mass quality classification of Hexi gold deposit,it is determined that the ore rock is medium stable.According to the shape of the ore body and the stability of the ore rock,the mining method is optimized.It is determined that the mechanized upward horizontal layered tailings cemented filling method is adopted,and the process design of ore block layout,mining,mining and filling is carried out.The practice shows that the ore production capacity of the mechanized upward horizontal layered tailings cemented filling method is adopted in Hexi Gold Mine reaches 180 t/d,the loss rate is 8.00%,the dilution rate is 10.00%,and the operation safety and work efficiency are improved.
