摘　　要：新城金矿矿体赋存在断裂破碎带中,矿体及围岩破碎,开采难度大。为进一步提高采场生产能力,结合矿体赋存状况,提出上向水平分层充填采矿法。该采矿方法采用无轨出矿设备,实现了断裂带中破碎矿体的安全高效开采,有效防止了冒顶、片帮等安全事故。经工业试验,取得了铲运机台效300 t/台班,矿块生产能力220 t/d,以及采矿损失率和矿石贫化率分别为9.93%和7.89%的良好指标。研究成果也可为类似条件的矿山开采提供借鉴和参考。The ore bodies in Xincheng Gold Mine are hosted in fractured and broken zones. The ore bodies and surrounding rocks are broken,thus hard to extract. In order to further increase production of stopes,the paper proposed upward horizontal slicing and filling method for mining considering the hosting conditions of ore bodies. The method used trackless ore-drawing equipment and achieved safe and efficient extraction of ore bodies from fractured and broken zones,and effectively prevented accidents such as roof falling and wall caving. Industrial tests show that the method can achieve 300 t ores per shift for 1 scooptram; produce 220 t/d ore blocks; and the mining loss and ore dilution rate are 9. 93 % and 7. 89 % respectively; the indicators are good. The research achievement can be used as reference by mines that have similar conditions.
