| 摘 要： | 新塘铜矿大凹子矿段,开拓方式为平硐开拓,生产规模为3万t/a,是个小型矿山。矿山原采用浅孔留矿法、有底柱分段崩落法进行开采,随着开采深度的增加,有底柱分段崩落法不再适用该矿山的开采,故选用浅孔留矿法和分段凿岩阶段出矿空场法进行开采。试采结果表明,选用的采矿方法方案,降低了损失贫化率及劳动强度,提高了矿山生产的安全性及经济效益。

| Abstract: | The development way of Daaozi ore section of Xintang copper mine is flat adit development with production scale of 30000 t / a,which belongs to small-scale mine.The mine originally adopted short-hole shrinkage method and sublevel caving medium-deep hole exploit.With the increasing of mining depth,sublevel caving medium-deep hole is not suitable for the exploitation of this mine,thus short-hole shrinkage method and sublevel drill and benching ore removal and open stope method are adopted by this mine.The mining test shows that the adopted mining methods can reduce ore loss and dilution rate,improve the mine production safety,reduce labor intensity and increased economic benefit as well. |
