  • 上向水平分层充填采矿法回采技术改进及应用……贾旭峰,赵龙,任绍勇,万博闻
  • 摘 要:江西金山金矿体以缓倾斜薄至中厚矿体为主,针对部分10 m以上的中厚矿体,提出了采用上向水平分层充填采矿方法开采,并对凿岩爆破工艺进行改进,提出了一种浅孔凿岩扇形布孔的回采工艺。通过在江西金山金矿的实践表明:该技术可操作性强,采场生产能力由67 t/d提高到124 t/d,降低了采矿成本,保障了作业安全性,增加了企业经济效益。

    Renovationof upward horizontal slicing and filling mining method and its application……JiaXufengZhao LongRen ShaoyongWan Bowen

    AbstractThe ore bodies of Jinshan Gold Mine in Jiangxi aremainly gently inclined thin to medium thick ore bodies.The study came up withupward horizontal slicing and filling mining method to mine part of the mediumthick ore bodies with the thickness over 10 m,and renovated the drilling andblasting process,leading to a short-hole drilling and fan-shaped hole alignmenthigh-efficient stoping process.The practice in Jinshan Gold Mine in Jiangxishows that the process is highly applicable,raising the stope productioncapacity from 67 t/d to 124 t/d,lowering mining cost,guaranteeing operationsafety and improving profitability for enterprises.
